Cruise Control In Cars Explained (And How To Safely Use It)

car cruise control meaning

Have you ever wished you could set your car's speed and just sit back and relax while driving on a long stretch of highway? If that's the case, then cruise control is just the ticket you've been searching for—and the good news is, it's a standard feature in most cars these days!

Cruise control is a handy feature for drivers that allows you to maintain a constant speed without having to keep your foot on the gas pedal. In this post, we'll explore how cruise control works, its benefits, and how to use it safely to make your driving experience more comfortable.

Understanding Cruise Control

Cruise control, also known as speed control, is an electronic system that allows you to maintain a specific speed without manually controlling the accelerator pedal. The system uses sensors and electronic components to control the throttle and keep your car moving at a desired speed. First introduced in the late 1950s, cruise control has since become a standard feature in most modern vehicles you see on the road today.

How Does It Work?

At its core, cruise control involves a series of sensors that monitor the vehicle's speed and a control unit that regulates the throttle. When the driver sets the cruise control to a specific speed, the system adjusts the throttle to maintain that speed. If the car begins to slow down because of an incline (e.g. going up a hill), the system will open the throttle to accelerate. Conversely, if the car starts to speed up due to a declin (e.g. going downhill), the system will close the throttle to decelerate.

Modern cruise control systems also come with additional features like adaptive cruise control (ACC), which uses radar or cameras to detect vehicles ahead and automatically adjusts the speed to maintain a safe following distance (more on this BELOW).

The History of Cruise Control

The invention of cruise control can be traced back to the late 1940s and early 1950s, when engineer Ralph Teetor developed the first-speed control system. This innovative feature was designed to help drivers maintain a steady speed, reduce fatigue while driving, and improve fuel efficiency. Over the years, cruise control technology has undergone significant advancements, leading to the development of sophisticated systems like adaptive cruise control.

Types of Cruise Control Systems

Today, drivers can choose from a range of cruise control systems, each with its own unique features and functionalities.

Conventional Cruise Control

Conventional cruise control is like your old reliable friend. It's pretty basic and doesn't have any fancy bells and whistles. You just set the speed you want, and it'll keep your car cruising along at that speed, no problem. It's perfect for those long drives on open highways, but it doesn’t automatically react to other cars on the road.

So, if the car in front of you slows down, you'll need to step in and adjust your speed manually. This trusty system comes standard on most cars and is great for saving some fuel on those long road trips .

Adaptive Cruise Control (ACC)

Now, if conventional cruise control is your old reliable friend, then Adaptive Cruise Control (ACC) is like that friend's tech-savvy younger cousin. ACC isn't just maintaining your set speed, it's also keeping an eye on the car in front of you. If that car slows down, ACC slows your car down to keep a safe distance .

It's like having an extra set of eyes on the road, making highway driving a breeze. Plus, some ACC systems can even handle stop-and-go traffic, bringing your car to a full stop and then picking up speed again when traffic gets moving.

Predictive Cruise Control

Predictive Cruise Control is like the fortune teller of cruise control systems. It uses GPS and map data to see into the future and predict what's coming up on the road, like hills or curves, and adjusts your speed accordingly. This means you get a smoother ride and better fuel efficiency, but it all depends on the quality of the GPS and map data. If that's a bit out of date, your fortune-telling cruise control might not be so accurate. It's usually found in more high-end vehicles where top-notch fuel efficiency is a focus for the engineers.

Cooperative Adaptive Cruise Control (CACC)

And then we have Cooperative Adaptive Cruise Control, or CACC. This is like the team player of cruise control systems. It allows cars to talk to each other, coordinating their speeds to maintain a safe distance. It's like having a well-coordinated team of cars all working together to make the traffic flow smoother and reduce congestion. Picture it like a synchronized dance on the highway, where every car knows its place and keeps the right distance. This tech is still pretty new, but it's got a lot of potential. Imagine a future where traffic jams could be a thing of the past.

Remember, these systems are here to make your drive smoother and safer, but they're not a replacement for your attention. No matter how fancy your cruise control is, these systems can be greatly influenced by external conditions like weather and traffic, and they should always be used as aids, not replacements, for attentive driving.

Common Cruise Control Symbols and Indicators

Understanding the various symbols and indicators associated with cruise control is important for safe and effective usage. These symbols typically appear on the dashboard (or on the side of the steering wheel) and may include a speedometer icon, "SET," "RES" (resume), and "CANCEL". Be sure to consult your vehicle's owner's manual for specific details and explanations of these symbols.

Benefits of Using Cruise Control

Cruise control offers several benefits to drivers, especially during long road trips or highway driving.

Fuel Efficiency

One of the main advantages of using cruise control is improved fuel efficiency. By maintaining a constant speed, cruise control helps reduce fuel consumption, leading to better gas mileage. Rapid acceleration and deceleration, on the other hand, can lead to increased fuel consumption.

Comfort and Convenience

Cruise control allows drivers to take their foot off the accelerator pedal, reducing fatigue and improving comfort during long drives. It also helps drivers avoid unintentionally exceeding the speed limit by setting a maximum speed.

When used correctly, cruise control can contribute to safer driving. By maintaining a steady speed, it reduces the likelihood of erratic driving behavior and potential accidents. However, it is important to note that cruise control shouldn't be used in certain conditions, such as heavy traffic or slippery roads .

Troubleshooting Common Cruise Control Issues

Occasionally, you may encounter issues with your cruise control systems. Common problems include cruise control not engaging or disengaging unexpectedly. Possible causes may include a faulty brake light switch, malfunctioning sensors, or issues with the control module. If you experience any problems with your cruise control, it's best to have a qualified technician diagnose and repair the issue for you.

Cruise Control and Road Etiquette

Practicing proper road etiquette while using cruise control is essential for a safe and pleasant driving experience. Here are some tips on how to use cruise control courteously:

  • Avoid using cruise control in heavy or congested traffic, as it may hinder your ability to react quickly to changing conditions.
  • Be mindful of other drivers when setting your speed. Avoid setting a speed that's significantly slower or faster than the flow of traffic.
  • If you are in the passing lane and using cruise control, be sure to adjust your speed or temporarily disengage the system to allow faster-moving vehicles to pass.
  • Always signal your intentions, such as lane changes or exiting the highway, even when using cruise control.

The Future of Cruise Control Technology

Cruise control technology plays a vital role in the development of autonomous vehicles, or self-driving cars . In autonomous vehicles, cruise control systems work together with other advanced driver assistance systems (ADAS) to enable the vehicle to operate without direct driver input. These systems include lane-keeping assist, automatic emergency braking, and collision avoidance systems.

As autonomous vehicles become more sophisticated, cruise control technology is evolving to support higher levels of automation. For example, some autonomous vehicles are equipped with advanced cruise control systems that can navigate complex traffic scenarios, merge onto highways, and even change lanes autonomously.

While fully autonomous vehicles are still in the developmental stages, the integration of cruise control technology is a big step toward creating safer and more efficient transportation systems.

As automotive tech continues to advance, cruise control systems are becoming more intelligent and capable. Here are some potential developments we can expect to see in the future of cruise control technology:

  • Integration of artificial intelligence (AI) to improve decision-making and responsiveness in adaptive cruise control systems.
  • Enhanced connectivity and vehicle-to-vehicle (V2V) communication, enabling cars to share information about traffic conditions and coordinate their speeds for smoother traffic flow.
  • Greater customization and personalization options, allowing drivers to set preferences for cruise control behavior, such as following distance and speed adjustments.

Overall, the future of cruise control technology holds promise for creating a more seamless and enjoyable driving experience, with a focus on safety, comfort, and sustainability.

Debunking Myths About Cruise Control

Let's address and debunk some common misconceptions about cruise control:

Myth : Cruise control can be used as a substitute for driver attention.

Fact : Cruise control is a driver assistance feature, not a replacement for attentive driving. Drivers should always remain alert and ready to take control when necessary.

Myth : Cruise control increases the risk of accidents.

Fact : When used appropriately, cruise control can contribute to safer driving by maintaining a steady speed and reducing erratic driving behavior.

Cruise control is a valuable feature that can enhance your driving experience by providing comfort, convenience, and fuel efficiency. Remember to use it safely and appropriately based on driving conditions, and always stay attentive while on the road.

cruise control

Cruise control is an invaluable feature on Ameri­can ­cars. Without cruise control, long road trips would be more tiring, for the driver at least, and those of us suffering from lead-foot syndrome would probably get a lot more speeding tickets.

­Cruise control is far more common on American cars than European cars, because the roads in America are generally bigger and straighter, and destinations are farther apart. With traffic continually increasing, basic cruise control is becoming less useful, but instead of becoming obsolete, cruise control systems are adapting to this new reality -- soon, cars will be equipped with adaptive cruise control, which will allow your ­car to follow the car in front of it while continually adjusting speed to maintain a safe distance.

In this article, we'll learn how a conventional cruise control system works, and then we'll take a look at adaptive cruise control systems that are under development.

What Cruise Control Does

Cruise control acceleration and deceleration, controlling the cruise control, adaptive cruise control.

car cruise control meaning

The cruise control system actually has a lot of functions other than controlling the speed of your car. For instance, the cruise control pictured below can accelerate or decelerate the car by 1 mph with the tap of a button. Hit the button five times to go 5 mph faster. There are also several important safety features -- the cruise control will disengage as soon as you hit the brake pedal, and it won't engage at speeds less than 25 mph (40 kph).

The system pictured below has five buttons: On, Off, Set/Accel, Resume and Coast. It also has a sixth control -- the brake pedal, and if your car has a manual transmission the clutch pedal is also hooked up to the cruise control.

  • The on and off buttons don't actually do much. Hitting the on button does not do anything except tell the car that you might be hitting another button soon. The off button turns the cruise control off even if it is engaged. Some cruise controls don't have these buttons; instead, they turn off when the driver hits the brakes, and turn on when the driver hits the set button.
  • The set/accel button tells the car to maintain the speed you are currently driving. If you hit the set button at 45 mph, the car will maintain your speed at 45 mph. Holding down the set/accel button will make the car accelerate; and on this car, tapping it once will make the car go 1 mph faster.
  • If you recently disengaged the cruise control by hitting the brake pedal, hitting the resume button will command the car to accelerate back to the most recent speed setting.
  • Holding down the coast button will cause the car to decelerate, just as if you took your foot completely off the gas. On this car, tapping the coast button once will cause the car to slow down by 1 mph.
  • The brake pedal and clutch pedal each have a switch that disengages the cruise control as soon as the pedal is pressed, so you can shut off the cruise control with a light tap on the brake or clutch.

car cruise control meaning

The cruise control system controls the speed of your car the same way you do -- by adjusting the throttle position . But cruise control actuates the throttle valve by a cable connected to an actuator , instead of by pressing a pedal. The throttle valve controls the power and speed of the engine by limiting how much air the engine takes in (see How Fuel Injection Systems Work for more details).

In the picture above, you can see two cables connected to a pivot that moves the throttle valve. One cable comes from the accelerator pedal, and one from the actuator. When the cruise control is engaged, the actuator moves the cable connected to the pivot, which adjusts the throttle; but it also pulls on the cable that is connected to the gas pedal -- this is why your pedal moves up and down when the cruise control is engaged.

car cruise control meaning

Many cars use actuators powered by engine vacuum to open and close the throttle. These systems use a small, electronically-controlled valve to regulate the vacuum in a diaphragm. This works in a similar way to the brake booster , which provides power to your brake system.

car cruise control meaning

The brain of a cruise control system is a small computer that is normally found under the hood or behind the dashboard. It connects to the throttle control seen in the previous section, as well as several sensors. The diagram below shows the inputs and outputs of a typical cruise control system.

A good cruise control system accelerates aggressively to the desired speed without overshooting, and then maintains that speed with little deviation no matter how much weight is in the car, or how steep the hill you drive up. Controlling the speed of a car is a classic application of control system theory . The cruise control system controls the speed of the car by adjusting the throttle position, so it needs sensors to tell it the speed and throttle position. It also needs to monitor the controls so it can tell what the desired speed is and when to disengage.

The most important input is the speed signal; the cruise control system does a lot with this signal. First, let's start with one of the most basic control systems you could have -- a proportional control .

In a proportional control system, the cruise control adjusts the throttle proportional to the error, the error being the difference between the desired speed and the actual speed. So, if the cruise control is set at 60 mph and the car is going 50 mph, the throttle position will be open quite far. When the car is going 55 mph, the throttle position opening will be only half of what it was before. The result is that the closer the car gets to the desired speed, the slower it accelerates. Also, if you were on a steep enough hill, the car might not accelerate at all.

Most cruise control systems use a control scheme called proportional-integral-derivative control (a.k.a. PID control). Don't worry, you don't need to know any calculus to make it through this explanation -- just remember that:

  • The integral of speed is distance.
  • The derivative of speed is acceleration.

A PID control system uses these three factors -- proportional, integral and derivative, calculating each individually and adding them to get the throttle position.

We've already discussed the proportional factor. The integral factor is based on the time integral of the vehicle speed error . Translation: the difference between the distance your car actually traveled and the distance it would have traveled if it were going at the desired speed, calculated over a set period of time. This factor helps the car deal with hills, and also helps it settle into the correct speed and stay there. Let's say your car starts to go up a hill and slows down. The proportional control increases the throttle a little, but you may still slow down. After a little while, the integral control will start to increase the throttle, opening it more and more, because the longer the car maintains a speed slower than the desired speed, the larger the distance error gets.

Now let's add in the final factor, the derivative . Remember that the derivative of speed is acceleration. This factor helps the cruise control respond quickly to changes, such as hills. If the car starts to slow down, the cruise control can see this acceleration (slowing down and speeding up are both acceleration) before the speed can actually change much, and respond by increasing the throttle position.

Two companies are developing a more advanced cruise control that can automatically adjust a car's speed to maintain a safe following distance. This new technology, called adaptive cruise control , uses forward-looking radar , installed behind the grill of a vehicle, to detect the speed and distance of the vehicle ahead of it.

Adaptive cruise control is similar to conventional cruise control in that it maintains the vehicle's pre-set speed. However, unlike conventional cruise control, this new system can automatically adjust speed in order to maintain a proper distance between vehicles in the same lane. This is achieved through a radar headway sensor , digital signal processor and longitudinal controller . If the lead vehicle slows down, or if another object is detected, the system sends a signal to the engine or braking system to decelerate. Then, when the road is clear, the system will re-accelerate the vehicle back to the set speed.

The 77-GHz Autocruise radar system made by TRW has a forward-looking range of up to 492 feet (150 meters), and operates at vehicle speeds ranging from 18.6 miles per hour (30 kph) to 111 mph (180 kph). Delphi's 76-GHz system can also detect objects as far away as 492 feet, and operates at speeds as low as 20 mph (32 kph).

Adaptive cruise control is just a preview of the technology being developed by both companies. These systems are being enhanced to include collision warning capabilities that will warn drivers through visual and/or audio signals that a collision is imminent and that braking or evasive steering is needed.

What is cruise control in a car? Meaning and how does it work?

Cruising on the highway can be a lot of fun. However, it demands maintaining a constant speed for a long time. To achieve that, you need to press the accelerator pedal continuously, which can get tiring after a while. That’s when the cruise control feature of your car comes into play. So, what exactly does it do and how does it work? This article explains cruise control in a car and how to use it in different driving conditions. So, without stepping on the ‘brake’ pedal, read on!

Cruise Control in a Car

What is cruise control in a car?

It is a system that accurately maintains the speed set by the driver without any external intervention. It automatically controls the speed of a car and only allows the vehicle to hit a speed set by the driver. It does not allow the car to cross that speed limit. This feature has become common among modern cars. You can even find this feature in the top-spec variants of some of the affordable hatchbacks and sedans.

How does the cruise control system work?

Cruise control in a car replicates the inputs of a driver to control the vehicle’s speed. But instead of pressing the accelerator pedal, it uses a different mechanism to maintain a constant cruising speed.

Initially, the system used a cable to control the accelerator (throttle valve). You can find these mechanisms in older cars. It adjusted the vehicle's speed by engaging the throttle with the help of an actuator that is controlled by a cable. The throttle valve is responsible for the power and speed generated by the engine. So, depending on the speed set by the driver, the system automatically adjusted the throttle position.

But with the advent of technology in the automotive industry, the cruise control system in modern cars entirely relies on electronics. Instead of a cable, the system now communicates with the throttle via various sensors connected to a computer (ECU - Electronic Control Unit). So, when you set a speed, the ECU calculates the throttle position and engages the throttle wirelessly.

The system constantly maintains the speed set by you (driver) irrespective of road conditions. For example, if there’s an incline ahead, cruise control adjusts the throttle accordingly to maintain the same speed.

How to use cruise control?

Before engaging the cruise control in a car, remember that the system is not intended to be used in adverse weather conditions. For example, you may refrain from driving the car at cruising speeds when it’s raining heavily. The low visibility and unpredictable road conditions make it unsafe to drive at such speeds. So, always be mindful of the weather condition and your surroundings before engaging the system.

Here are the steps to use cruise control.

Step 1 - Before activating cruise control, build up speed by accelerating the car. However, do not cross the speed limit of that particular road/highway.

Step 2 - Once your car reaches the desired speed, activate cruise control. Generally, the system activation button will be on the steering wheel. However, locating the exact button when the vehicle is parked is better to avoid any distractions while driving.

Step 3 - Next, you can take your foot off the accelerator pedal. If you have set the cruise control correctly, the car should maintain the cruising speed.

Step 4 - Keep your eyes on the road as it is very easy to get distracted when the car is accelerating automatically.

Step 5 - If you wish to accelerate when the cruise control is engaged, you can press the ‘+’ button on the steering wheel to briefly engage the accelerator pedal.

Step 6 - To decelerate, press the ‘-’ button on the steering wheel. You can also tap on the brake pedal. However, as a safety precaution, almost all cars will deactivate the cruise control as soon as you press the brake pedal.

The buttons to activate cruise control or accelerate/decelerate may vary from one car to another. So, do check the owner’s manual before fiddling around with the system. It’s better if you are familiar with the controls before driving the vehicle, as it will avoid unnecessary distractions.

How to install cruise control in a car?

Can you install cruise control in a car? The answer is both yes and no. You may install an aftermarket kit if it’s an old car that does not rely on electronics to control all the engine-related functions. But installing such a kit becomes almost impossible in modern cars due to the complex electronics.

It is a complex process to install the system in new cars as you have to fiddle with electronics, and it also requires the fitment of hardware. So, it can only be done during the time of car manufacturing. Moreover, if you try installing an aftermarket kit, you may void the warranty offered by the OEM (Original Equipment Manufacturer). On top of that, it is not recommended to go for an aftermarket cruise control kit as it may compromise safety.

Newly launched cars are equipped with cruise control except for a few entry-level models. So, instead of investing in retrofitting a system, it's better and safer to spend that money on buying a car with a built-in system.

Adaptive cruise control

The new technology also allows the system to automatically adjust the car's speed depending on the speed of the vehicle ahead. This feature is known as adaptive cruise control. It ensures that the car maintains a safe distance from the vehicle ahead despite the constant change in speed of the vehicle moving ahead. It is instrumental in highways or during rush hour traffic and reduces driver fatigue.

It is also a level 1 autonomous driving system. The system uses radar sensors to calculate the speed and distance of the car ahead. For instance, if the vehicle in front of you slows down/speeds up, a car with adaptive cruise control will reduce speed/accelerate automatically without any external inputs.

You can find this feature in premium cars. But gradually, it is trickling down to not so expensive cars as well. Adaptive cruise control is a part of an advanced driver assistance system.

Pros and cons of cruise control

Cruise control makes driving easy and convenient, and at the same time, it also takes care of safety. But like every other feature, it has its own set of advantages and disadvantages, which are elaborated in the following section.

Below are some of the pros of the cruise control system.

Reduces driver fatigue: The primary role of cruise control is to maintain a constant speed without you having to step on the accelerator pedal. That means you can rest your right foot and can stay relaxed. It is helpful when you drive long distances on highways where you need to maintain a constant speed for long durations.

Improves fuel economy: When maintaining a constant speed, the engine will not get stressed as it need not change the intensity of operation. To put it in a simple way, when the engine runs at constant RPMs (Revolutions Per Minute) , it consumes less fuel. Hence, when driving long distances on highways, the cruise control system can improve fuel economy.

Helps to drive within the speed limit: You may drive at normal speed on busy urban roads. But when you hit the wide and smooth highways, you may end up crossing the speed limit. You may not even realise that you have crossed the speed limit until you glance at the speedometer. Cruise control can help you in this regard as you can easily set a speed limit and let the system do the work. The system will not allow the car to go over the speed set by you.

Increase/decrease speed with a click of a button: Typically, you use the accelerator and brake pedal to increase/decrease the speed of your car. But when the cruise control is engaged, you can even use the buttons to do the job for you. However, ensure that you are familiar with the functions of the buttons, as it may feel unnatural in the beginning. It is best to practice using the buttons in a safe environment before using them on public roads.

Works well with automatic cars: Cruise control works best with automatic cars as you need not worry about changing gears. The ECU or the onboard computer shifts the gears automatically when there is a change in speed and works well when cruising automatically. It means you only need to focus on steering the vehicle.

As mentioned earlier, cruise control also has some cons, which are listed below.

Limited use on Indian roads: Cruise control is suited for wide and long highways where drivers follow the rules. Although India has some excellent highways, many drivers may disregard rules which creates an unpredictable environment. Also, cattle, dogs and other animals may venture into public roads and make the situation even more tricky. Hence, it may be challenging to cruise at high-speeds.

Hampers reaction time: As mentioned above, the roads in India are unpredictable. You may have to perform emergency braking to avoid any obstacles on the road. When driving with manual controls, your right foot will be on the accelerator pedal, and it is easy to move your foot to step on the brake pedal in an emergency. But, when using cruise control, your right foot will be resting on the floor of the car, and it may take a bit more time to reach the brake pedal. This difference in reaction time may be the difference between you avoiding an obstacle or crashing into it.

Can induce drowsiness: If you use cruise control for long durations, you may end up feeling drowsy. Since the car is accelerating at a constant speed, your alertness level may drop in the long run. Hence, it is recommended that you manually control the vehicle once every 10-15 minutes when using the automatic cruising feature on highways.

Cannot use at night: Cruise control is of no use during night drives as the visibility is poor. Even with well-lit roads, the visibility is not as good as daylight. So, allowing the car to maintain a constant speed may be a safety concern, even on roads that are familiar to you.

It does not work well with manual cars: In a manual car, you have to change gears by yourself. The cruise control will handle the acceleration/deceleration, but you still need to shift the gears manually to maintain the optimum RPM. It can be irritating at times when you need to slow down and accelerate immediately. It may not be a dealbreaker, but it kind of refrains you from experiencing the full potential of the automatic cruising system.

Cruise control vs adaptive cruise control: Key differences

The below table highlights the key differences between cruise control and adaptive cruise control.

What is the difference between cruise control and speed limiter?

Sometimes you may get confused between cruise control and speed limiter as both are related to the car's speed. Refer to the table below to understand the difference between both the systems.

List of cruise control cars In India

Cruise control is a feature that we can see in a lot of cars. Gone are the days when this feature was limited to premium vehicles. Even vehicles with affordable price tags are equipped with intelligent features. Here’s the list of popular cars with the automatic cruising system.

List of adaptive cruise control cars in India

Adaptive cruise control is the more advanced version of the standard automatic cruising system. Currently, this system can be seen only in premium cars in India. Below is the list of popular cars with adaptive cruise control.

Frequently asked questions

Here are some of the most commonly asked questions related to cruise control in cars.

No, it is not a standard feature in cars. However, almost all vehicles costing above Rs. 5 lakhs are equipped with cruise control.

It is not advisable to install an aftermarket cruise control kit in your car as new vehicles have complex electronics. Moreover, installing such a kit involves a complicated process, and it may also void the warranty provided by the car manufacturer.

Typically, the cruise control button is located on the steering wheel for easy access. However, the location of the button may vary depending on the make and model.

Yes, you can use cruise control in a manual car. However, you need to manually control the gear shifts when the vehicle slows down or accelerates when the system is engaged.

What is Cruise Control

Cruise Control Explained – All You Need to Know

Zutobi

Cruise control has come a long way since first invented and patented by Ralph Teetor in 1950, who originally named it the “Speedostat”. Chrysler Corporation was the first manufacturer to offer the groundbreaking mechanism as an option on several of its luxury vehicle models nine years later. Today, cruise control is rapidly becoming the standard on all new vehicles, providing drivers with increased convenience on their daily drive.

As you’re learning how to operate a vehicle , understanding cruise control will help increase your comfort behind the wheel and knowledge of driving.

What is Cruise Control?

Cruise control is an electronic device within your vehicle that controls the speed of your vehicle. It allows the driver to maintain a constant speed of 25 mph without holding their foot on the accelerator. Although the feature has been around for 70 years, automotive manufacturers continue to improve upon the technology to provide drivers with increased comfort, luxury, and convenience whenever they’re behind the wheel.

cars driving on a freeway with little traffic

Different Types of Cruise Control

There are 3 types of cruise control systems.

  • Speed Limiter
  • Adaptive Cruise Control
  • Semi-autonomous Cruise Control

What is a Speed Limiter?

A speed limiter will limit how fast the driver can accelerate behind the wheel. All modern vehicles contain a standard speed limiter capping speed between 120 mph and 180 mph depending to protect the vehicle’s engine and discourage reckless driving. However, an additional limiter can be added as an option in many European-made cars, as well as Tesla, Ford, and Nissan. Drivers are still required to keep their foot on the pedal to keep their vehicle in motion, but will not be able to accelerate past a predefined speed limit.

What is Adaptive Cruise Control?

Adaptive cruise c ontrol uses sensors around the vehicle’s exterior to maintain speed while keeping a safe following distance from the car ahead. The system will slow you down and speed you up as the flow of traffic fluctuates throughout your commute, removing a lot of the stress from daily driving. However, adaptive cruise control may not work well in bad weather or protect you from sudden movements, so you will want to always keep your full attention on the road.

What is Semi-autonomous Cruise Control?

Luxury automakers such as Tesla and Audi are implementing the newest rendition of cruise control on their latest vehicle models – Semi-autonomous Cruise Control. It works largely the same as adaptive cruise control, but assists drivers with lane guidance and steering. There are several variations of semi-autonomous cruise control that include additional convenience features for the driver.

How to Use Cruise Control – 6 Step Guide

These are the steps to using cruise control effectively.

  • Observe weather conditions
  • Build speed
  • Engage cruise control
  • Set cruise control
  • Watch the road and steer
  • Brake to disengage

1 – Observe weather conditions

As mentioned, cruise control may become inconsistent in rainy, snowy, or otherwise hazardous conditions. If you must drive in this situation, it may be a better idea to do so manually. Cruise control works best on a clear day with constant traffic flow.

2 – Build speed

Accelerate to your desired speed as you prepare to activate cruise control. US highways have posted speed limits between 55 mph and 75 mph. Do not attempt to set cruise control when you are traveling over the speed limit.

3 – Engage cruise control

Once you’ve reached your desired speed, engage the cruise control. This step will vary widely based on your vehicle make and model, however, many cruise control settings are accessible from the steering wheel controls. Check your owner’s manual for further information.

4 – Set cruise control

After turning on cruise control, you’ll need to set your desired speed. Many systems set the cruise control at the current speed, while others require you to manually set one. You can increase and decrease this speed as needed without interrupting the mechanism.

5 – Watch the road and steer

Watching the road is essential when cruise control is engaged. Cruise control is not a substitute for a human driver and will require supervision at every step. If you are using a semi-autonomous system, you will not need to steer but will need to keep at least one hand on the wheel for safety measures.

6 – Brake to disengage

When cruise control is no longer needed, or you need to quickly make a maneuver, simply apply pressure to the brakes to disengage the system. Once deactivated, you will be in full control of your vehicle once again.

When NOT to Use Cruise Control

While cruise control is a convenient feature for modern drivers, it is not perfect for all circumstances. In fact, utilizing the system can be quite dangerous if you’re not careful. Be sure not to use cruise control under these conditions.

Heavy Traffic

Heavy, or stop-and-go traffic is not ideal for safely using cruise control. When engaging cruise control on the highway, ensure your lane is clear and there are no vehicles stopping ahead.

Wet or Icy Conditions

You need to be driving slowly while on wet and icy roads. While cruise control keeps a constant, predetermined speed, it takes away a lot of the manual control needed to stay safe when it’s raining or snowing.

City Driving

While driving through the city, you’ll face a number of stop lights and stop signs that will require manual braking. This action will automatically disengage cruise control.

Winding Roads

Winding roads require more attention than straight, flat streets. Cruise control systems, even adaptable cruise control, may not always detect these streets correctly, causing accidents.

Fatigued Driving

Driving while fatigued is never a good idea, but even less so while using cruise control. Utilizing the system may add to your fatigue, as you give your vehicle more control of the journey. If you’re even the least bit tired, you should never turn on cruise control.

As you can see, cruise control is a great way to relieve much of the stress that comes with everyday driving. The constant rate of speed can also drastically improve fuel efficiency for longer drivers. Cruise control has had a positive impact on the driving industry for 70 years and shows no signs of disappearing anytime soon.

We’re sorry we don’t support the car you are looking for. Please enter its make, model, and year below so that we can add support for it.

Operating Cruise Control

Step 1 Locate your car's cruise control switches.

  • Check your car's operating manual if you are unable to find the cruise control switches.

Step 2 Study the layout of the switches.

  • Many cars have additional buttons to increase or decrease speed (marked by a +/-) when using cruise control.

Step 3 Drive your car until you reach your desired speed and hit “SET.”

  • For some car models, cruise control will not operate below a certain speed, such as 40 miles (64 km) per hour.

Step 4 Stop cruise control whenever you need to.

  • To stop cruise control briefly (such as when a car in front of you brakes), just press the brake as you normally would.
  • If you are driving a manual, you can also disengage cruise control by pressing the clutch.
  • If you are completely done using cruise control, you can press the “OFF” or "ON/OFF" switch.
  • If your car has a cruise control “CANCEL” switch, you can also press that to stop it.

Step 5 Resume cruise control, if you want.

  • If your car has a +/- button for cruise control, press this when you want to raise or lower your car's speed.

Using Cruise Control Safely and Efficiently

Step 1 Reserve cruise control for the open road.

  • Using cruise control on busy streets can also be dangerous. Since you yourself are not in complete control of your car, you may be paying less attention. You might brake or react to other cars more slowly than normal, increasing the chance of an accident.

Step 2 Avoid using cruise control in hazardous conditions.

  • Wet or snowy roads
  • Hilly, steep, or mountainous areas
  • Winding roads

Step 3 Stay focused on the road.

Does a PHEV like the 2024 Mazda CX-90 Hybrid make sense in rural Canada?

What is cruise control a comprehensive guide.

When the system is set, cruise control will maintain a steady speed for your vehicle

Article content

Your vehicle’s cruise control system unlocks numerous benefits at the touch of a button — but according to web search data, drivers still have plenty of questions about what it is, what it does, and how it works.

What is Cruise Control? A Comprehensive Guide Back to video

Below, we’ll answer some of the most popular Internet search questions about cruise control, so you can make the best use of this important system.

What is Cruise Control?

With cruise control, your vehicle will maintain a steady speed when the system is set.

What is adaptive cruise control?

With adaptive cruise control, the vehicle will also automatically slow down and speed up to maintain a safe position in traffic.

How does cruise control work?

Cruise control work with a manual transmission just the same way it does with an automatic.  Drivers set their cruising speed with a button press, and the system works the throttle automatically to maintain the desired cruising speed as evenly as possible. In some vehicles with a manual transmission, pressing the clutch pedal to shift gears turns the cruise control off, requiring an additional button press to reengage it after a gear change.

In other cars with a manual transmission, pressing the clutch pedal simply pauses the cruise control system a moment, allowing drivers to complete their gearshift. When they’ve released the clutch, the cruise control picks up where it left off — no additional button press required.

Is cruise control more fuel efficient?

Yes.  Increasing your vehicle’s speed uses fuel. While cruising, even a highly competent driver who isn’t using cruise control will tend to slow down and speed up in a repeated cycle, possibly several times per minute. Though fluctuations in speed may be slight, they do cause your engine to use more fuel than required. Point is, the more time you spend at a steady speed, the less fuel your engine needs.

For most drivers, using cruise control on the highway at 80 km/h can reduce fuel consumption by about 20 per cent. For drivers who find difficulty in maintaining a steady speed and frequently experience big fluctuations, using cruise control can cut fuel use by over 40 per cent.

Depending on what you drive and how fast you drive it, using cruise control could save you between $4 and $20 per hour — based on information from Natural Resources Canada that shows most drivers who don’t use cruise control on the highway will tend to experience a 10 km/h speed fluctuation about three times per minute.

Drivers who have the most difficulty managing their cruising speed could be using 60 per cent more fuel than they need to.

Is cruise control bad for your transmission?

No.  Your vehicle’s engine, transmission and other components are designed to work hand-in-hand with its cruise control system and are extensively tested and integrated with one another for trouble-free performance.

Using cruise control also reduces wear and tear on both your engine and transmission by running things more smoothly and steadily, and reducing workload on both components.

Can you add cruise control to a car?

Yes.  Depending on the year, make and model, cruise control may be available for add-on or retrofit. Professional installation is recommended, and you’ll want to talk to a professional about the specific availability of parts and integration for your vehicle.

In many cases with modern cars, it’s generally easier and more cost effective to just opt for a unit equipped with cruise control from the factory. Cruise control is widely available as standard equipment on most modern vehicles.

Can cruise control get stuck?

Yes , but it’s extremely rare. Older cable-based cruise control systems seem more prone to this rare problem, in which the cable can slip or bind, making the throttle stick into position. More modern vehicles with electronic throttle and monitoring systems make this problem even less likely.

If the cruise control on your car fails to disengage when you want to slow down, slip the vehicle into neutral to disconnect drive power from the wheels, pull over, and address the situation.

However, chances are, you’ll never experience this problem.

When should cruise control be used?

Any time you’re trying to drive at a constant speed.  Whether around town at 60 km/h, in a residential area at 40 km/h, or out on the highway at 105 km/h, switching the cruise control on makes for a smoother and more fuel efficient drive that’s easier on your engine and transmission. it can also help you do your part to maintain the steady and efficient flow of traffic.

Most cruise control systems can be engaged at speeds above 30 km/h.

When should cruise control not be used?

Any time you can’t safely drive at a steady speed.  If the road surface is snowy, icy, slushy or very wet, you’ll want to think twice about switching your cruise control on.

In older cars, having your cruise control engaged on a wet or icy road could allow the vehicle to accelerate or experience wheelspin when driven wheels encounter a low-traction surface. Here, the cruise control system maintains throttle pressure, even in situations where it should be released instead. This could lead to a loss of control.

In more modern vehicles, electronic monitoring is used to automatically disengage cruise control when one of the following happens:

  • one or more wheels slip
  • one or more wheels leave the surface of the road after a major bump or dip
  • the wipers are set to the maximum speed setting in heavy rain

Use your judgement. Safely navigating certain slippery or dangerous driving conditions requires careful manual control of your vehicle’s throttle, and in these situations, you’re best to leave the cruise control off.

What causes cruise control to kick off?

If the cruise control in your vehicle suddenly kicks off, a few things may be to blame.

Sometimes, cruise control disengages automatically when the vehicle’s automatic wipers detect heavy rainfall, or when a wheel spins or (briefly) leaves the surface of the road after a big bump or dip. In other situations, there may be a problem with one or more sensors or switches, including the brake pedal switch, throttle position sensor, or one or more wheel speed sensors.

Your modern cruise control system relies on various sensors and switches to do its job properly. As a failsafe, any problem with these sensors can cause the cruise control system to go offline. If you notice this happening regularly, have your vehicle diagnosed by a professional.

Will the cruise control work with an ABS light on?

Probably not.  Your car’s Antilock Braking System works hand-in-hand with your cruise control system, and any fault with the ABS system will typically take your cruise control offline until it’s fixed.

An ABS warning light in your instrument cluster can indicate one of several major problems or malfunctions, so be sure to have a professional investigate as quickly as possible.

Will cruise control apply the brakes?

No, but adaptive cruise control will.  Standard cruise control (simply called cruise control) holds your vehicle’s speed as constant as possible once set. More advanced adaptive cruise control systems use camera or radar-based sensing to determine the traffic situation in front of your vehicle, and can automatically apply the brakes to maintain a pre-set following distance.

With cruise control, drivers need to brake to slow down as they close in on a slower vehicle in traffic. With adaptive cruise control, the system makes these braking inputs automatically, and the vehicle speeds back up to its pre-set cruising speed once traffic clears.

Before you buy, be sure to determine which type of cruise control system is fitted to the car you’re considering.

What is Super Cruise?

Super Cruise is a next-level driver assistance feature available on certain GM vehicles.

With Super Cruise, the vehicle uses special GPS hardware and sensors to accurately compare its position to a 3D map of pre-qualified highways .

On these pre-qualified highways, Super Cruise allows drivers to go hands-free for extended periods as the vehicle automatically maintains its cruising speed, adjusts that speed for changing traffic conditions, and even precisely follows the curves in the road. It can even make hands-free lane changes.

Super Cruise is not an autonomous system, and in order for it to work, drivers need to keep their eyes on the road — there’s even a camera that monitors the position of the driver’s eyes to make sure they’re focused on the road ahead.

What is Cruise Control and How Does it Function in a Car?

What is Cruise Control and How Does it Function in a Car?

A Quick Overview

Driving on long stretches of highway can be tiring, especially when trying to maintain a constant speed. Cruise control alleviates this by allowing drivers to set and maintain a desired speed without continuous use of the accelerator pedal. Understanding how cruise control functions can help drivers make the most of this convenient feature.

What is Cruise Control?

Cruise control is an automotive feature that enables drivers to set a desired speed for their vehicle. Once activated, the cruise control system maintains the set speed without the need for constant pedal input. It helps drivers maintain a steady pace on long trips, providing convenience and reducing the likelihood of unintentional speed fluctuations.

How Does Cruise Control Function?

Cruise control systems may vary slightly among different vehicle models, but they generally function using the following components and controls:

1. Set Button

To activate cruise control, the driver typically presses a “Set” button or engages a switch on the steering wheel or dashboard. This action captures the current speed of the vehicle and sets it as the target speed for the cruise control system to maintain.

2. Speed Control

Once the cruise control system is activated, the driver can adjust the speed using speed control buttons. These buttons allow the driver to increase or decrease the set speed in small increments. By pressing the appropriate button, the driver can fine-tune the desired speed for their comfort and road conditions.

3. Resume Button

The “Resume” button, also known as the “Accel” button, allows the driver to restore the previously set speed after it has been canceled or temporarily interrupted. When the driver presses the “Resume” button, the cruise control system accelerates the vehicle to the previously set speed.

4. Cancel Button

The “Cancel” button, often marked with the symbol “CRUISE” or “OFF,” deactivates the cruise control system. Pressing this button disengages the system and allows the driver to regain full control over acceleration and braking. It is important to note that the brake pedal can also automatically deactivate cruise control when pressed.

Advantages of Cruise Control

Cruise control offers several advantages to drivers:

  • Reduced Driver Fatigue: Cruise control allows drivers to maintain a steady speed without continuously pressing the accelerator pedal, reducing fatigue on long drives.
  • Improved Fuel Efficiency: By maintaining a consistent speed, cruise control can help optimize fuel efficiency by reducing unnecessary acceleration and deceleration.
  • Avoiding Speeding: Cruise control helps drivers adhere to speed limits by maintaining a set speed, preventing unintentional speeding due to variations in foot pressure on the accelerator pedal.

Limitations of Cruise Control

While cruise control provides convenience, there are limitations to consider:

  • Traffic and Safety: Cruise control should be used only in appropriate situations. It is important to remain vigilant and be ready to take control of the vehicle when necessary, such as in heavy traffic or hazardous road conditions.
  • Hilly Terrain: Cruise control may struggle to maintain a constant speed on hilly terrain, as it cannot anticipate changes in elevation. In such situations, the driver may need to manually intervene and adjust the speed accordingly.

What is cruise control?

Cruise control is a technology in cars that allows drivers to maintain a constant speed without keeping their foot on the accelerator. The feature is commonly used during long drives on highways or other open roads.

How does cruise control work?

When cruise control is activated, the driver sets a desired speed for the car to maintain. The car’s engine and transmission work together to maintain that speed without any input from the driver.

Is it safe to use cruise control while driving?

Yes, cruise control is generally safe to use while driving. However, drivers should remain attentive and ready to take control of the car at any moment. It’s also important to note that cruise control should not be used in hazardous weather or road conditions.

What are the benefits of using cruise control?

Using cruise control can improve fuel efficiency by helping drivers maintain a consistent speed and reduce unnecessary acceleration. It can also reduce driver fatigue during long drives by allowing them to rest their feet.

Can all cars have cruise control installed?

Not all cars come with cruise control as a standard feature, but many newer cars do have this option available. Additionally, aftermarket cruise control systems can be installed on most cars.

Can cruise control be dangerous?

Cruise control can become dangerous if the driver becomes too reliant on it and fails to remain attentive. Additionally, using cruise control in hazardous conditions, such as heavy traffic or inclement weather, can be dangerous.

Does cruise control work on manual transmission cars?

Cruise control can be installed on manual transmission cars, but it requires a more advanced system than the one used for automatic transmissions. Manual transmission cruise control systems are typically more expensive and less common.

What is Cruise Control in Car? How to Use? Parts, Types, Benefits

Cruise control in automobiles may be a feature you may notice in several new cars. The feature permits you to effortlessly drive at a homogenous speed, particularly on long routes that have minimum or no frequent turns and stops. Whether or not you drive a sedan, an SUV, or the other car, your feet would like some rest while driving for an extended time.

This can be wherever the controller system takes over. The cruise control system delivers optimum convenience by protecting the accelerator of the car at a preset speed, sanctioning the driving force to require their foot off the pedal and sit comfortably.

A fleet manager should take into account the cruise control feature, in particular, when expanding their fleet when considering the addition of modern vehicles with a host of gadgets and gizmos.

As compared to earlier cruise control systems that clumsily maintained the vehicle’s speed at about the same level, the adaptive cruise control automatically adjusts its speed based on traffic conditions and road proximity.

What is Cruise Control? Definition

An automated system lets a driver set a speed without external assistance. It regulates the speed of a car automatically, allowing the car to reach the speed set by the driver.

what cruise control car how use parts types benefits

You can find this feature even in some of the top-spec variants of some of the affordable hatchbacks and sedans. This feature prevents the car from exceeding the speed limit.

Function of Cruise Control

When a car is equipped with cruise control, the driver can control the speed using the brake pedal. Instead of pressing the accelerator pedal, cruise control uses a different mechanism to keep a constant speed.

You can still find older cars that use cable-controlled accelerators. An actuator controlled by a cable engages the throttle to increase the vehicle’s speed. Depending on the drive speed, the system automatically adjusts the throttle valve position based on the power and speed generated by the engine.

  • The cruise control system in modern cars is entirely dependent on electronics due to technological advancements in the automotive industry.
  • Instead of a cable in the new system, various sensors connect to a computer ECU or Electronic Control Unit, which calculates the throttle position and engages the throttle wirelessly.
  • No matter the road conditions, cruise control keeps you at the speed you choose. For instance, if there’s an incline ahead, the throttle will adjust accordingly to allow you to maintain the same speed.
  • When fatigue affects your reaction time, you may not be able to avoid danger if you use cruise control. Cruise control not only steers your car but also applies your brakes on most cars.

Parts of Cruise Control

Vehicle speed sensor.

When the set button is pressed, the cruise control module attempts to maintain the vehicle’s speed as a result of information provided by the Vehicle speed sensor over the network.

Cruise Control Switch

Basic control switches have on or off, set or accelerate, and resume buttons.  The control switch is the electric switch that’s accustomed to controlling the assorted functions of the cruise control system. once the cruise control is activated, the vehicle can maintain the set speed or acceleration while not the motive force has to tread the accelerator pedal.

Brake Switch

Brake switches communicate the driver’s intent to slow down, and the current speed is reactivated using the resume function.

When you press the brake pedal, the stoplight switch turns the brake lights on.

It is an integral part of your braking system and lets the driving force behind you recognize that you’re retardation down. It additionally incorporates a direct influence on your ABS, controller system, and more.

Throttle Position Sensor

The throttle position sensor, or TPS, indicates the angle of the throttle plate to the PCM. The greater the angle is the greater the engine rpm will be. Some cruise control systems are throttle-activated, controlled by engine vacuum to a spring-loaded solenoid.

The actuator is typically controlled by a module and is an electromechanical system. A vehicle’s engine management system usually controls an electronic actuator.

How Does Cruise Control Work?

The driver activates this system with the help of steering mounted controls. Normally, switches like ON, OFF, SET, or ACCL are available.

They differ greatly from manufacturer to the manufacturer; since ON and OFF represent activation and deactivation, while SET or ACCL control actual speed.

Hence, the system determines the vehicle speed from the speed of the driveshaft. However, the vehicle must reach that speed before setting.

The throttle can also be set at a specific location using the wheel speed sensors. Additionally, most manufacturers use vacuum-operated actuator mechanisms to hold the throttle in place.

When the driver touches the brake or clutch pedals, nearly every cruise control system will be disabled. That means that these systems are programmed so that they will turn off when a driver touches them.

It is true that electronics, when cruising down a mostly level highway, tend to avoid the little speed-ups or slow-downs caused by an inattentive mind or a weary accelerator ankle.

The changes in momentum lead to wasted fuel since force equals mass times acceleration. Using cruise control is particularly advantageous on primarily level terrain as well as long, steady grades up or down.

If you’re driving on a highway traversing rolling hills, you would be better off maintaining a steady speed. As a result, it allows your vehicle to slow down by about 5 or 10 mph when climbing & accelerate by about the same amount when decelerating.

It is also important to be aware that most of the gas-saving hints here apply to extending the range of an electric vehicle. However, a lot of the energy an electric car expends climbing a hill is recovered by regeneration on the way down as you can leave the cruise on.

Types of Cruise Control

While cruise control isn’t something you can innovate on, car companies have come up with adaptive cruise control and advanced adaptive cruise control.

Adaptive Cruise Control

A camera, radar, laser array, or a combination of these three installs in the car’s front for adaptive cruise control. That continuously checks for traffic and can detect if there is an approaching car.

After this, the system will adjust the speed of your car so that instead of closing on a slower-moving car, it will follow it at a set distance controlled by the driver. The car will keep matching the speed of the car in front until it changes lanes, exits the road, or if the driver moves.

Advanced Adaptive Cruise Control

The advance adaptive cruise control adds the extra layer of ensuring that the driver is never speeding by adjusting the speed limit to match the speed limit of the road they’re driving on. It is typically paired with lane-keeping assistance as well as autonomous emergency braking.

A highly advanced system will be able to follow cars at high speeds on a motorway as well as crawl autonomously in a stop-and-go traffic queue. Automatic transmissions usually pair with these systems to prevent excessive or under-revving by an inattentive driver. The cruise control is normally disengaged when the clutch is engaged & the gears are changed in manual transmissions.

Can you manually install cruise control in your car?

Installing an aftermarket kit in an old car that did not rely on electronics to control all the engine-related functions may possible. But in modern cars with complex electronics, it becomes difficult to install such a kit.

New cars require a complex process for installing the system as you have to deal with electronics along with fitting hardware. Therefore, the process can only be carried out during the manufacturing process.

The installation of an aftermarket cruise control kit may also void your warranty provided by the Original Equipment Manufacturer, and it is not recommended since it could compromise safety.

The majority of newly launched cars come with cruise control, with the exception of a few entry-level models. Instead of spending that money on retrofitting a system, buying a car with a built-in system makes more sense.

Can you think about replacing Cruise Control to Adaptive Cruise Control?

You can choose from a variety of adaptive cruise control systems. A small unit mounts behind or in front of the grille. A laser system is used in some cases.

ACC can be changed from standard cruise control using some systems, while other systems use stereoscopic cameras. Depending on the system you choose, you will be able to change. Depending on the manufacturer, some models come with kits you can install.

For example, you will need to modify the bumper or grille to accommodate the system. Additionally, you might have to modify the vehicle’s electrical system and other key components as well.

Is Cruise Control healthy for your engine?

Cruise control is truly helpful for your automotive as a result it cuts back on manual acceleration. Additionally, to straining the motive force on extended trips, manual acceleration also can modify the engine over time.

Abrupt acceleration from a dead stop can create the engine and transmission work more durable than usual. Several controller systems share equivalent sensing element inputs because of the car’s transmission. This leads some folks to believe victimization the options an excessive amount of effects on the engine.

How anyone can diagnose Cruise Control?

A quick diagnosis can be to hold the pedal up with the highest of your left foot at constant time as you’re participating the controller whereas on a take a look at drive. If the cruise control tries to set, then the brake switch can presumably be adjusted. Adjustment of the brake switch is extremely common.

Benefits of Cruise Control

Despite the various edges it offers, your drivers could also be hesitant to use controllers because the perceived loss of control is redoubtable if they’re unacquainted with such a system. Admittedly, they in all probability won’t build abundant use of the system on inner-city routes, however once they move long distances on the country like Germany roads or major highways, cruise control will be a useful asset.

Reduce Fuel Consumption

If you maintain a constant speed, the engine won’t be stressed since its intensity will not change. In a nutshell, the engine consumes less fuel when it runs at constant RPMs.

Therefore, a cruise control system can reduce fuel consumption when driving long distances on highways.

Speed Control with ease

If you have cruise control engaged, you can use the buttons instead of the accelerator or brake pedals to increase or decrease your car’s speed. Be sure to familiarize yourself with the function of all the buttons before using them on the road, as it may feel unnatural at first. Practice using them in a safe environment before using them on the road.

Accident less driving

When driving on urban highways, you may not realize that you have exceeded the speed limit until the speedometer shows that you have crossed it. You may drive at a normal speed when traveling on busy urban streets, but when you hit wide and smooth highways as you may exceed the speed limit.

You can use cruise control in this regard as you can easily set a set speed limit and let the system do the work. The system won’t allow the car to exceed its set speed.

Automatic car Uses

With automatic cars, cruise control works best because you don’t have to worry about changing gears. The onboard computer or the electronic control unit automatically shifts the gears when the speed changes. That means you only need to focus on steering.

Driver Fatigue Reduction

You can have cruise control while driving long distances on highways if you need to maintain a constant speed but don’t want to have to step on the accelerator. That means your right foot can stay relaxed and you can stay relaxed.

Proper Control

There are few things as frustrating to a driver & their family and friends as obtaining a dashing ticket. Cruise control, of course, permits the vehicle to stay to a prescribed speed, eliminating the danger of acquiring such a fine.

Drawbacks of Cruise Control

Less reaction time.

It is possible to have to perform emergency braking to avoid obstacles on the road. It is easy to move the foot of the right foot to step on the brake pedal if you are driving with manual controls. In an emergency, your foot will be on the accelerator pedal.

If you’re using cruise control, your right foot will rest on the floor of the car, meaning it will take a bit more time to reach the brake pedal. The difference in reaction time may dictate whether or not you avoid an obstacle.

Risky in Night Drives

Even on well-lit roads at night, the visibility is poor, so cruise control is of no use during a night drive. So, maintaining a constant speed may be hazardous in night, even on roads you’re familiar with. Plus, some drunken drivers would violate the on road rules and may come on your car’s path at night. Cruise Control might not detect it, so you should keep eyes open while you driving at night.

Less Anticipation in Hill Roads

In terms of saving fuel, control works best wherever the tract in all fairness flat. However, on roads with major accent descents, control cannot anticipate the road ahead the means an alert driver can.

An alert driver can recognize that the simplest way to save fuel is to be as light-weight on the accelerator as potential, whereas keeping the automobile during a gear as high as possible for the terrain to cut back engine revs.

Within the case of undulating terrain, the alert driver will enable the car to hurry up slightly on down-hills, and carry that momentum through to uphill sections, while not manually change down a gear one or two.

In control mode, the automobile’s laptop will merely instruct the car to take care of a particular speed, and on down hills this will truly mean the car is braking, whereas on the subsequent uphill it’ll then not benefit from momentum that a driver can have dialed in.

Do not use in manual transmission car

Cars with manual transmission require that you change the gears manually. Cruise control takes care of acceleration and deceleration, but you must shift gears to maintain the optimum RPM.

You may occasionally have to accelerate and slow down instantly, which can be annoying. While it’s not a deal breaker, it does prevent you from experiencing the full capabilities of automatic cruising.

Shifting Problem in Hill Road

Of course in extreme up-hills, the motive force ought to downshift a gear or additional to keep up momentum. Here it’s a judgment turn whether or not to easily pull down the accelerator tougher to maintain speed, or keep a relentless accelerator position and manually downshift to a lower gear.

Tests with fuel flow meters have found that, generally, it is higher to bit by bit depress the accelerator to maintain speed on up-hills, however to not labor the engine during a high gear. It is important to downshift one gear at the optimum point when speed drops off uphill, so that the engine remains in its optimum power range, and at that point you will slowly ease off the gas to keep speed within the lower gear.

In Cruise Control, the car’s electronic management units are prioritized to maintain that set speed despite fuel usage, or gear selection, and this may mean that it’ll actually use additional fuel than necessary, in an undulating terrain.

High Speed issue in Highways

There are some excellent highways, but many drivers fail to follow the rules, creating an unpredictable environment. Although cruise control can work well on wide, long highways with drivers who follow traffic rules, it does not work well on narrow highways with drivers who disregard traffic rules. Additionally, cows, dogs, and other animals may wander onto public roads, making for a challenging situation when cruising at high speed.

Alternatives of Cruise Control

Cooperative adaptive cruise control.

It is important to distinguish between cooperative adaptive cruise control and automated truck which represents an intermediate step towards a long-term vision of closely-coupled automated trucks.

In the first place, only the truck speed control will be automated with Cooperative Adaptive Cruise Control, using vehicle-to-vehicle communication to complement forward sensing. It is still the driver’s responsibility to steer actively, maintain lane, monitor traffic conditions, and monitor the roadway.

Secondly, instead of using a constant-distance gap control strategy, a constant-time gap control strategy has been incorporated into cooperative adaptive cruise control, where the distance between vehicles is proportional to the speed.

The reason for that is a string of trucks configured with Cooperative Adaptive Cruise Control is called a string rather than a platoon. A major focus of this report is describing the various Cooperative Adaptive Cruise Control operational concept alternatives at the level of individual vehicles and their drivers. The four major operational concepts are string formation; steady-state cruising, string split maneuvers, and faults or abnormal operating conditions.

Dynamic Radar Cruise Control

Conventional cruise control helps you control your speed and enjoy your ride while driving. However, when you are constantly forced to change your speed, especially on busy highways, the feature is hardly worth it. As with conventional cruise control, Dynamic Radar Cruise Control allows vehicles to travel at a constant speed set by the driver on highways.

Additionally, Dynamic Radar Cruise Control helps maintain a preset distance to the preceding vehicle by automatically adjusting your vehicle’s speed when the preceding vehicle is traveling at a slower speed. When your vehicle’s system determines no hazards ahead, it automatically returns to your previously set speed.

Tips to use Cruise Control in car

Weather checking.

When the roads are safe, a car’s cruise control is designed to be used in clear weather. When using cruise control on a long drive, it’s important to keep in mind the effect of the climate. 

It is extremely dangerous to switch to cruise control in rainy or snowy weather.  As a result, the driver must make cautious decisions based on his judgment in such weather. When you travel & keep an eye on the weather conditions, read the forecasts, and assess the risks.

Pay Attention

When driving a car with cruise control, you must remain alert so that you can enjoy the ease it provides. Stay alert because the vehicle isn’t completely under control. It is not an artificial intelligence system, despite its usefulness. A major accident cannot be predicted by a computer, but you are the only one who can prevent it.

Traffic and Road Consideration

On roads with little or no traffic, the cruise control should be engaged in a car.  The cruise control won’t limit your car’s speed if your car is too close to another vehicle. Because of this, it’s best not to use cruise control on roads with heavy traffic. 

Gain Proper Knowledge of Cruise Control before Operating

Prior to using cruise control on the road, you should understand how cruise control works in a car. Newer car models have buttons on the steering wheel for activating the cruise control mechanism. Older cars have stalks to operate the system, but most newer models have buttons on the steering wheel.

You should also set speed limits once the cruise control mode is on. You must be able to adjust the speed of the cruise control if you have an advanced car model. Thus, make sure you are aware of all the features that your car offers and how to utilize them when required.  

Do keep your pedal

During long drives, cruise control is incredibly helpful for resting your right foot. However, it is essential that you always keep your foot on the accelerator or brake pedals so that you can react instantly whenever you need to slow down or increase your speed.

When you are driving a car that has adaptive cruise control that maintains a safe distance between you and the vehicle in front of you, you should always have your foot on the brake. It is better to give yourself an added sense of safety when you and your vehicle are on the road.

It is not safe to rely on safety features like autonomous braking, as they are meant to be used only in emergencies.

Don’t go for High Speed

On the highway, cruise control should not exceed 100 km/h because it is illegal and dangerous. You ought always to adhere to speed limits; so for example, you shouldn’t go beyond 100 km/h with your cruise control.

Pay attention on your Surroundings

If your car has cruise control or its adaptive form, that does not mean you are free to let it drive. You will still have to control the steering and other inputs. That is why you need to remain aware of your surroundings.

Even though you can rest while driving when you activate your cruise control, you must still be aware of the things happening around you. Despite this feature is on, you should not be distracted by your phone while driving and stay focused throughout the long drive. You keep your eyes on the road, not your phone.

Do not idle on Left while activating Cruise Control

You already know that the leftmost lane has been reserved for overtaking as it is not supposed to use for any other purpose. Hogging this lane will slow down traffic because there will always be someone faster than you.

It is illegal to hog the leftmost lane for any reason, but the most important is the following: in an emergency, the leftmost lane is the emergency lane. Those who need to speed should always be able to pass so it can always be clear of vehicles.

Keep a safe distance on car in front

You need to maintain a safe distance between your car and the one in front, since most cruise controls cannot detect the car in front and keep a safe distance. That’s why maintaining focus will help you maintain that safe distance.

The difference in space between two vehicles can lead to shorter brake distances, which is risky when you are running 100 km/h. Follow the three-second rule, and keep in mind that the cruise control you find in mass-market cars isn’t as sophisticated as what’s available in Mercedes or other high-end vehicles

Don’t forget to keep your hand on steering wheel

Although it might be tempting to let go of the steering wheel while driving in a straight line, you should not do at all costs. Road-leveling can affect your car’s direction, so keep both hands on the wheel so that you stay within the lane. Moreover, it is always better to have both hands on the steering wheel when abruptly changing directions than to have fewer or none at all.

Frequently Asked Questions

When you may consider using cruise control.

If you are driving on an open road with little or no traffic, you can use the cruise control system. You can relax your legs at a constant speed while driving during long, exhausting hours.  In the same vein, only turn on cruise control if you can maintain the legal speed limit for the entire trip.

Do you know at what speed cruise control works?

If driving on associate degree interstate, the regulation is mostly between fifty-five and seventy miles per hour. This speed varies is right for control. You don’t arrange to set your vehicle’s cruise control at a speed that’s higher than the legal limit.

When should you not using Cruise Control?

Don’t use the controller once it’s raining, snowing, or when there are wet & icy roads in general. Whereas some newer vehicles have options that facilitate your automobile to handle wet roads and rain even while the cruise is on, it is best to be in total control of your car once you are driving in these conditions.

What Is Cruise Control In A Car and How It Works

What Is Cruise Control

According to the research , cruise control reduces the mental workload of the driver. It reduces fatigue and increases the comfort of driving a long distance. It is also good to avoid speed violations and resists the temptation to speed up the car.

Although cruise control can be a great help on long trips by maintaining a consistent speed and freeing up the driver’s hands, it is important to remember that it is not a replacement for a driver’s attention and care. Drivers must still be vigilant in paying attention to the road and their surroundings, and be prepared to take over control of the vehicle if necessary. Additionally, drivers should periodically check the vehicle’s speed to ensure that it is still within the desired range.

Fortunately, on this page, you can learn everything you need to know about cruise control. In this powerful article, you are going to quickly learn what cruise control is in a car.

Cruise Control Icon

Cruise Control also known as speed control or auto cruise is a system that allows you to keep the car at a constant speed without holding your foot on the accelerator pedal. Technically, it is an electronic feature that reprograms the car’s setting to keep the car at a constant speed regardless of pressing and holding the foot on the accelerator pedal.

This cruise control is a kind of driving on auto-pilot mode. It automatically controls the car’s steady speed by taking the control of the throttle body. It comes in cars having a drive-by-wire system where an electronically controlled throttle body is manipulated by a cruise control computer. The cruise control computer is a small computer that you can fit under the hood or in the cabin behind the dashboard.

Two Cable Mechanical Throttle

In the early mechanical linkage throttle body, two cables are used for operating the cruise control, one cable goes to the accelerator pedal, and the second cable goes to the vacuum actuator to operate the throttle body for cruise control.

This vacuum actuator also pulls the cable connected to the accelerator pedal and actuates the throttle butterfly valve. Modern cruise control systems have a memory feature which means, it remembers the last time the cruise control system was canceled.

You can resume the previously canceled speed by tapping on the RES button. With the activated cruise control system, you can override the speed of the car by pressing the accelerator pedal. But once, you take the foot off the accelerator pedal, the cruise control reduces the speed until it reaches the last SET speed.

This is an Alert Some cars do not engage the cruise system below a certain speed, typically less than 40 km/h or 25 mph.

Frequently Asked Questions (FAQs)

The purpose of cruise control is to maintain a constant speed by automatically adjusting the throttle. This can be beneficial for the driver, as it reduces the need to repeatedly adjust the accelerator pedal. Additionally, it may help to improve fuel efficiency and emissions by reducing the amount of time the engine spends idling. However, cruise control is not without its drawbacks – it can lead to overuse of the brakes and increased wear on the tires, and it may not be suitable for all road conditions.

The cruise control feature on a car does not drain the battery. This is because the cruise control system is not continuously running when engaged, but rather it only activates when the car is traveling at a consistent speed. When activated, the cruise control system will automatically adjust the throttle and brakes to maintain a set speed, which takes very little power from the battery. Therefore, engaging the cruise control feature will not cause your car’s battery to drain any faster than if you were driving without it.

What Is Adaptive Cruise Control?

Adaptive cruise control (ACC) is a system designed to help road vehicles maintain a safe following distance and stay within the speed limit. This system adjusts a car's speed automatically so drivers don't have to.

control buttons on steering wheel in a modern car

Adaptive cruise control (ACC) is a system designed to help vehicles maintain a safe following distance and stay within the speed limit. This system adjusts a car's speed automatically so drivers don't have to.

Adaptive cruise control is one of 20 terms used to describe its functions so that you might see adaptive cruise control as the following in advertisements and vehicle descriptions:

  • Active cruise control
  • Dynamic cruise control
  • Radar cruise control
  • Automatic cruise control
  • Intelligent cruise control

ACC functions by sensory technology installed within vehicles such as cameras, lasers, and radar equipment, which creates an idea of how close one car is to another, or other objects on the roadway. For this reason, ACC is the basis for future car intelligence.

These sensory technologies allow the car to detect and warn the driver about potential forward collisions. When this happens, red lights begin to flash, and the phrase 'brake now!' appears on the dashboard to help the driver slow down. There might also be an audible warning.

Advantages of Adaptive Cruise Control

Limitations of adaptive cruise control.

Although there are many advantages to adaptive cruise control, there are still limitations to consider. One of the main faults in this system is the fact that it is not entirely autonomous. The driver of the vehicle still needs to practice safe driving habits that will work in tandem with this technology to produce the best results. Similarly, adverse weather conditions like snow, rain, or fog might confuse the system's sensors, as well as environmental factors such as driving through tunnels.

What Is the Difference Between a Level 1 Autonomous Car and a Level 2 Autonomous Car?

According to SAE International, when a car only has autonomous cruise control , it is considered to be a level 1 autonomous car. In contrast, a vehicle with autonomous cruise control and an additional feature, such as lane control, gets classified as a level 2 autonomous car.

How Much Does an Adaptive Cruise Control System Cost?

According to ExtremeTech, The cost of an adaptive cruise control system will vary depending on how many features you want. If you're going to have an ACC with all available features, you should be willing to pay anywhere between $2000 and $2500. If you are looking for minimal cruise control that would benefit speeds of up to 20-25 miles per hour, these more basic ACCs can cost as low as $500. The good news is that as ACC becomes more common, it will most likely reduce in price.

History of Adaptive Cruise Control

U.S. News says Mitsubishi first introduced adaptive cruise control in Japan in 1992 . This was a lidar-based distance detection system that detected objects that were getting too close. It was labeled as 'Debonair' and it was programmed to provide a warning to the driver about oncoming objects. The main difference was that it was the driver's job to apply the brakes and reduce their speed.

However, two years later in 1995, the Mitsubishi Diamante featured an upgraded approach to the Debonair called 'Preview Distance Control.' Unlike the original technology, this laser-powered system could adjust a driver's speed by downshifting or controlling the throttle. The driver was still responsible for applying the brakes.

From the early 2000s onward, big names in the car industry, such as Ford, BMW, Mercedes, Cadillac, Volkswagen, Infinity, Hyundai, Toyota, and Audi, created their versions of adaptive cruise control in their vehicles. These individual features have evolved into a high-tech system with automatic braking and speed control.

Types of Adaptive Cruise Control

Radar-based systems.

According to eInfoChips, radar-based systems work by placing radar-based sensors on or around plastic fascias to detect your vehicle's surroundings. Each radar sensor works together to create a comprehensive picture of the vehicle's proximity to other cars or potentially hazardous objects. This type of sensor can look different depending on the design and model of the car.

Laser-Based Systems

As mentioned by Electronic Design , this type of ACC system operates out of a large black box typically placed in the grille of your vehicle. It uses laser technology to detect the proximity of objects to your car. It does not operate well during rainstorms and other weather conditions.

Binocular Computer Vision Systems (Optical)

According to ExtremeTech, this is a relatively new ACC system put into use in 2013. It uses small cameras that are placed on the back of a vehicle's rearview mirror to detect front-facing objects.

Assisting Systems

Assisting systems are radar-based add-ons that customers can buy together. These pre-crash systems can offer lane control, brake assistance, cruise control, proximity alerts to objects like corners, and steering power.

Multi-Sensor Systems

According to Fierce Electronics , adaptive cruise control systems sometimes integrate more than one type of sensor to aid in a vehicle's operation. Multi-sensor systems incorporate several different sensor types to provide a driver with advanced information. These sensors might include GPS data equipment or cameras to gather information about a vehicle's geographic environment and proximity to other cars.

Predictive Systems

As mentioned by Autoblog, prediction systems are a type of ACC that uses sensory data to predict the actions of neighboring vehicles. This means that your car might slow down to brace for another vehicle suddenly switching lanes and, in doing so, promotes passenger safety.

Adaptive cruise control is evolving each year. Car companies are continuously making adjustments to this technology and, in doing so, creating more common and affordable options that can be purchased with a new car or added to older car models, making driving safer for everyday people.

Advanced Driver-Assist Systems Make Our Lives Easier (and Safer)

Sadly, millions of people are involved in car crashes every year. According to the CDC, about 90 people die each day in the U.S. as a result of a car crash. However, crash fatalities are decreasing almost every year, even though there are more cars on the road. While the reasons for the decline aren’t clear-cut, advances in overall vehicle safety and advanced driver-assist systems seem to be contributing to the decline.

While most of today’s cars offer multiple driver-assist features, cruise control is still arguably one of the greatest advancements in the history of car technology. Interestingly, the feature was first invented over 60 years ago. Since then, there have been notable improvements that make the latest versions of cruise control safer and much more useful. 

The invention of cruise control, along with its evolution to adaptive cruise control, marked the beginning of what may eventually lead to self-driving cars. Continue reading to learn all about adaptive cruise control.

The History of Cruise Control

Various forms of cruise control were used in cars dating all the way back to the beginning of the twentieth century. However, modern cruise control was invented by American engineer Ralph Teetor in 1948. He secured a patent for the technology in 1950, and it made its way into passenger cars by the 1960s.

Teeter came up with the idea while riding along in a car with his lawyer. As a passenger in the car, he noticed that every time his lawyer talked, the car changed speeds.

Adaptive cruise control’s roots date back to 1992 when Mitsubishi launched a Lidar-based distance-detection system in Japan. However, the technology didn’t adjust the car’s speed on its own, but rather alerted the driver to take action. 

By 1995, Mitsubishi improved the system to adjust the car’s speed on its own via transmission and throttle management, though actual braking was still controlled by the driver. In the early 2000s, many automakers started offering their own, more advanced versions of adaptive cruise control.

What Is Cruise Control?

To most people, this may seem like a silly question. However, to better understand the evolution of cruise control, it’s important to take a look at its basic functionality.

Cruise control is a system designed to automatically control a vehicle’s speed, which the driver must pre-set after activating. It’s most useful for long highway or freeway drives, and/or in areas where there’s not much traffic, or a need to stop often. Cruise control isn’t very useful at low speeds, or in areas where there are many stop signs or traffic lights.

With cruise control engaged, you don’t have to keep your foot on the accelerator pedal or work to maintain a consistent speed. This means you can more easily adjust your seating position, rest your legs and feet, and focus on other aspects of driving. As an aside, keeping a car at a consistent speed typically leads to better fuel economy.

The controls and buttons for cruise control vary among vehicles. Typically, they’re found on either the steering wheel or a stalk on the steering column. The driver holds a steady speed using the accelerator pedal and then “sets” the speed before taking their foot off the pedal. There are also “+” and “-” buttons to change speed incrementally, as well as a button to disengage the feature and/or resume the pre-set speed. Touching the brake pedal immediately turns off cruise control.

Adaptive cruise control (ACC) is a system that helps cars stay within the speed limit or the pre-set speed while maintaining a safe, predetermined distance behind a “leading” car. When the vehicle in front of you speeds up or slows down, the system adjusts the car’s speed as necessary. 

Some advanced adaptive cruise control systems have “stop-and-go” technology – sometimes called traffic jam assist. This means the system will, when necessary, bring the car to a complete stop, wait for traffic to clear or for the leading car to begin moving, and then accelerate again to the speed limit or pre-set speed. The system continues to maintain a safe distance throughout these maneuvers.

While adaptive cruise control is the most commonly used term for this technology, different automakers have different names for it. If you read that a car offers smart cruise control, active cruise control, automatic cruise control, dynamic cruise control, radar cruise control, or intelligent cruise control, be sure to find out exactly what the feature’s capabilities are.

Most importantly, find out if the feature adjusts the car’s speed on its own, and if it has stop-and-go capability. Be sure to test-drive any vehicle before buying or leasing it. Get acquainted with the adaptive cruise control feature during your test drive. Make sure you understand exactly how it works and what it’s capable of before moving forward with the transaction.

How Does Adaptive Cruise Control Work?

Various car manufacturers have different technologies for adaptive cruise control. However, the basic idea is the same. The car uses either a laser or radar to measure the distance to the leading vehicle. These are essentially the same lasers and radars used for features like forward collision warning and automatic emergency braking. They’re also used in vehicles with semi-autonomous technology. For this reason, it’s fair to say that cruise control was the first step toward what may eventually evolve into self-driving vehicle technology.

It’s important to note that some laser-based adaptive cruise control systems won’t function properly in inclement weather and/or if the sensors are wet or dirty. Radar-based systems are largely unaffected by weather or debris. While more systems employ radar than lasers, be sure to find out which technology your car – or the car you’re planning on buying – uses.

Adaptive cruise control isn’t often a standalone technology. Instead, it’s usually part of a suite of safety systems that work together. If a car has adaptive cruise control, it likely also has forward collision warning and automatic emergency braking. Some more advanced vehicles also have pedestrian detection, as well as systems that help keep your car in its lane, or even help steer the car on the highway when adaptive cruise control is engaged.

What Are the Limitations of Adaptive Cruise Control?

Like almost all vehicle safety technologies, adaptive cruise control is constantly improving. However, it’s still not a substitute for a human driver. While adaptive cruise control is meant to reduce stress and make driving easier, you still need to remain aware, engaged, and ready to take over the accelerator and brake pedal at a moment’s notice.

Adaptive cruise control isn’t meant to steer the car, though other complementary safety systems may help with steering as well. Adaptive cruise control systems with stop-and-go technology will monitor the car in front of you and adjust the speed accordingly. Some systems even observe speed limit signs and slow down around tight curves. With that said, if another driver slams on the brakes in front of you, cuts you off, or makes a sudden maneuver, you should immediately take over. Remember, some cruise control systems either won’t operate or shouldn’t be used in inclement weather.

While your car may also have features like automatic emergency braking, you can’t count on those features to do the job for you. Instead, the features are there just in case you don’t react quickly enough.

Should You Avoid Cars That Don’t Have Adaptive Cruise Control?

When searching for a new or used car, you should try to prioritize finding a vehicle with as many of the latest advanced driver-assist systems as possible. This is especially true if you plan to keep the car for many years. 

Safety is of the utmost importance when shopping for a car. As vehicle safety systems are improving rapidly, it doesn’t take long for a car’s safety systems to become dated or even considered obsolete. For this reason, making sure you have the latest advanced driver-assist systems means you’ll be able to keep your car for a longer period of time before its features are no longer consistent with the most up-to-date technologies.

Is Adaptive Cruise Control Worth it?

It depends. While any technology that will make your life easier and safer is arguably worth it, adaptive cruise control can be a pricey option in some cars. You may have to buy a trim above the base and/or add a package. However, in many cars, adaptive cruise control comes standard, usually as part of a full suite of active safety technologies.

When you’re shopping for a car, make sure it comes equipped with as many safety systems as possible. If you have your eyes on a vehicle, and you learn that it doesn’t include a suite of safety systems, find out how much it costs to add them. If it exceeds your budget, you may want to consider a competing model that includes adaptive cruise control and other safety systems as standard.

  • How does cruise control work?

“Connected to the accelerator, cruise control uses an actuator to control the throttle to maintain the pre-set speed. Adaptive cruise control is an enhanced system that manages the speed electronically.”

How Cruise Control Works

While driving on an open road for a long time, it would be pretty tiring to keep pressing the accelerator pedal. Cruise control is a feature that helps reduce such fatigue drivers would feel while driving a long distance. The system imitates the way human drivers drive. But instead of pressing the accelerator pedal, it uses an actuator to control the throttle and helps your car continue cruising at the same speed. 

The cruise control system used in older cars is connected to the accelerator through a cable to maintain the gas pedal in a certain position to keep the pre-set speed.   Whereas the system in newer cars electronically manages the speed through a program without a cable. Instead, a computer connected with various sensors and throttle controls operates the feature through a wireless system. This newer technology can automatically adjust the speed based on how fast the vehicle ahead is going while maintaining a safe distance.   It dramatically reduces drivers’ fatigue since drivers do not have to press and release the accelerator pedal repeatedly. Drivers will find the system particularly useful on highways or roads with traffic jams during rush hour.

Cruise Control vs. Adaptive Cruise Control

Adaptive cruise control is an advanced version of the existing cruise control system. With the conventional system, the vehicle cruises at the speed previously set by the driver without the need to keep pressing the accelerator pedal. On the other hand, the adaptive cruise control system does the same; however, it can also calculate the speed of the car ahead of you by using the data from radar sensors and automatically adjust the speed of your vehicle to keep a safe following distance between the vehicles. If the vehicle ahead slows down, the system detects the reduction of speed and operates the controls to decelerate your car. If the car in front of you changes to another lane, the system gives the engine a signal to accelerate and reach the initially set speed.

5 Road Trip-Ready Sports Cars With Adaptive Cruise Control

A daptive cruise control allows occupants to breathe a little easier at highway speeds. The function maintains speed and following distance to take the guesswork out of highway cruising. However, adaptive systems aren’t limited to posh, top-dollar luxury rides; some fly-by-feel sports cars offer the fire-and-forget driving feature without busting the bank, like the 2024 Ford Mustang and Subaru BRZ. 

These five sports cars will keep it cool on the highway with adaptive cruise control

  • 2024 Ford Mustang
  • 2024 BMW Z4
  • 2024 Nissan Z
  • 2024 Jaguar F-Type
  • 2024 Subaru BRZ

The 2024 Ford Mustang works adaptive cruise control into its Ford Co-Pilot 360 suite, along with pre-collision and park assists. As such, the Blue Oval’s tenured pony car got a little better at being less of a stereotype and more of a budget-friendly grand tourer (GT). 

The BMW Z4 gets a manual transmission option for 2024, along with a smart cruise control system that will maintain distance and speed so you don’t have to. Better yet, with a turbocharged 3.0L B58 inline six-cylinder engine up front, the Toyota GR Supra sibling is one of the fastest cars on this list. 

In addition to the Z4, the sports car segment yields a GR Supra rival with a 400-horsepower 3.0L V6 and a manual transmission option: the 2024 Nissan Z. Better yet, the Z comes with adaptive cruise control to handle long, monotonous trips on the seemingly endless highway system. 

Sure, the 2024 Jaguar F-Type is far from the affordable side of the expansive sports car segment. However, the British nameplate offers the smart cruise control option, whereas the closely comparable C8 Chevrolet Corvette Stingray omits the feature. 

Finally, the 2024 Subaru BRZ might be one of the last words in the world of affordable driver’s cars, but it isn’t exactly spartan. No, the BRZ, along with its mechanical sibling, the Toyota GR86, offers adaptive cruise control for comfy highway cruising, per TrueCar. 

Not every cutting-edge sports car boasts adaptive cruise control

The Subaru BRZ and Ford Mustang offer adaptive cruise control without breaking the bank. However, not every luxe sports car model prioritizes the feature. 

For instance, the 2024 Chevrolet Corvette Stingray goes without the option, despite being a much pricier option in the performance car market. Of course, not every sports car buyer is overly concerned with the smart cruise control system, instead focusing on razor-sharp driving dynamics.
