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. 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.
Cooperative Adaptive Cruise Control (CACC)
All cruise control systems must have the capability to be turned off explicitly and automatically when the driver depresses the brake pedal and often also the clutch. Cruise control systems frequently include a memory feature to resume the set speed after braking and a coast feature to reduce the set speed without braking. When the cruise control is engaged, the throttle can still accelerate the car, but once the pedal is released, it will slow down the vehicle until it reaches the previously set speed. The purpose of cruise control is to maintain a constant speed by automatically adjusting the throttle.
Different manufacturers have different cruise control features
Typically, ACC gets included in a trim level or some sort of optional driver-assistance package on new cars. In our most recent survey, we asked CR members to rate their experiences with the advanced safety and driver assistance systems on their model-year 2017 to 2022 cars. Respondents answered questions about their satisfaction with the systems. If it’s your first time using your car’s cruise control system — or if you’re not 100% sure how to turn on cruise control in your car —the process starts before you crank the engine. Get the car’s manual and learn what each cruise control button does. Different makes and models may have different combinations of buttons or features.

Ultimately, it's not hard to save on fuel if you let your vehicle automatically maintain a steady cruising speed. The new technology also allows the system to automatically adjust the car's speed depending on the speed of the vehicle ahead. 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. The leading edge of cruise control today is adaptive cruise control.
Moreover, installing such a kit involves a complicated process, and it may also void the warranty provided by the car manufacturer. Here are some of the most commonly asked questions related to cruise control in cars. 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.
Set distance for ACC systems
Every ACC system works slightly differently, says Kelly Funkhouser, manager for vehicle technology at CR. Not all systems work at low speeds, so drivers who plan to use ACC in slow traffic should check the limitations of any system they plan to buy. These particular systems will often have the words “traffic jam” or “stop and go” in their name.
Modern cruise control systems have a memory feature which means, it remembers the last time the cruise control system was canceled. 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.

Car Gear Every Driver Needs: A Car Door Step
While knowing how to use cruise control can reduce leg fatigue, it can require more mental concentration. The car will maintain speed even if road conditions change, so you must carefully pay attention to the road and traffic. When you’re using your car’s cruise control feature, don’t forget your defensive driving skills. If you have adaptive cruise control, you may need to set your distance so the system knows how much gap to leave between you and the car ahead of you. Some manufacturers include three settings, while others can have up to five. If you have ACC, the car will automatically brake and accelerate to keep the correct distance while generally maintaining your set speed when possible.
For instance, the cruise control pictured below can accelerate or decelerate the car by 1 mph with the tap of a button. 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). On the latest vehicles fitted with electronic throttle control, cruise control can be integrated into the vehicle's engine management system. Modern "adaptive" systems include the ability to automatically reduce speed when the distance to a car in front, or the speed limit, decreases. Level 2 – To qualify as Level 2, a vehicle must have at least two driver-assistance technologies.
While it offers substantial automation, it still requires driver supervision and isn’t fully autonomous. As always, drivers should consult their vehicle manual to determine which cruise control features are available and how to use them. The steering-wheel controls for some systems have buttons or toggles with labels like “Accel” and “Decel,” while others simply use up-and-down arrows to signify a button’s function.
Most systems do not allow the use of the cruise control below a certain speed - typically around 25 or 30 mph (40 or 48 km/h). It can use radar, laser, binocular computer vision systems, a forward-aimed camera, or some combination of these technologies to track the traffic ahead of your vehicle. It senses when that traffic flow slows or stops, reacting to maintain the preset following distance.
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. The buttons to activate cruise control or accelerate/decelerate may vary from one car to another.
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. 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 driver must manually bring the vehicle up to speed and use a button to set the cruise control to the current speed.
Within cruise control, you can typically also adjust your speed up and down using buttons. 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. BMW offers the Driving Assistant Professional system, which includes features like adaptive cruise control with stop-and-go, lane-keeping assistant, and traffic jam assistant. It’s designed for convenience and safety, providing a balanced mix of automation and driver control.
The systems use lasers, radar, cameras, or a combination of those. If traffic slows to a stop, most ACC systems will bring the car to a complete stop, then bring it back up to speed when traffic gets going again. Others work only within certain speeds and/or might not start to accelerate automatically. Once familiar with your car’s cruise control system, you can try it out. Wait for a moment when it’s appropriate to use cruise control before turning it on. Check that the road is clear, that weather conditions are good, and that you’re on a highway or a road where you won’t have to stop or change speed often.
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. Each system has its strengths and caters to different driving needs and preferences. Tesla’s FSD Beta is at the forefront of autonomy but requires active supervision. GM’s Super Cruise excels in hands-free highway driving, while Ford’s Co-Pilot360 focuses on safety and driver assistance for everyday use.
