The below table highlights the key differences between cruise control and adaptive cruise control. [8] “Everything You Need to Know about Cruise Control,” Dave Johnston, mycarmakesnoise.com/electronics/cruise-control-guide (accessed July 11, 2023). A governor was used by James Watt and Matthew Boulton in 1788 to control steam engines, but the use of governors dates at least back to the 17th century. On an engine, the governor uses centrifugal force to adjust the throttle position to adapt the engine's speed to different loads (e.g., when going up a hill).
The Future of Cruise Control Technology
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 If that's a bit out of date, your fortune-telling cruise control might not be so accurate.

They begin with no automation and wrap up with full automation, including vehicles without pedals or steering wheels. As stated earlier, some systems will bring your vehicle to a complete stop to match traffic flow. Even more intelligent systems can then accelerate as the traffic flow resumes. These are called assisting, predictive, and multi-sensor systems. This is only the case when driving for longer stretches on wide, clear roads, however.
Will cruise control apply the brakes?
The driver must be prepared to resume control in case of an emergency but otherwise doesn’t have command of the car. That is, the driver’s hands can be off the steering wheel and their attention elsewhere. 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.

Remember to use it safely and appropriately based on driving conditions, and always stay attentive while on the road. 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. So, if the car in front of you slows down, you'll need to step in and adjust your speed manually.

Modern "adaptive" systems include the ability to automatically reduce speed when the distance to a car in front, or the speed limit, decreases. Cruise control (also known as speed control, cruise command, autocruise, or tempomat) is a system that automatically controls the speed of an automobile. The system is a servomechanism that takes over the car's throttle to maintain a steady speed set by the driver. Simple to use, all you need to do is turn on the system in your vehicle, reach your desired cruising speed, and set it. The system then assumes control of the accelerator, maintaining the set speed until the driver engages the brake. Using cruise control can improve fuel efficiency by helping drivers maintain a consistent speed and reduce unnecessary acceleration.
Edit your picks to remove vehicles if you want to add different ones. If the cruise control in your vehicle suddenly kicks off, a few things may be to blame. 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.
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.

Add cruise control to one of your lists below, or create a new one. A PID control system uses these three factors -- proportional, integral and derivative, calculating each individually and adding them to get the throttle position. As mentioned earlier, cruise control also has some cons, which are listed below. While wheel alignment and balance both contribute to a smoother ride, the services are quite different.
Is cruise control more fuel efficient?
There continues to be plenty of confusion about self-driving or autonomous systems, what they are, and how they operate. However, the major difference between adaptive cruise control and a self-driving system is, ACC is simply a component of a driverless system. That is to say, ACC provides automatic braking and acceleration in a self-driving system that also includes steering, and sometimes automatic lane changing. As always, drivers should consult their vehicle manual to determine which cruise control features are available and how to use them. 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.
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. Early systems didn’t allow for presetting the maintained following distance. Consequently, a vehicle six or seven car lengths ahead of you moving into your lane became almost an airbag-deploying event.
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. Step 6 - To decelerate, press the ‘-’ button on the steering wheel.
It can also reduce driver fatigue during long drives by allowing them to rest their feet. 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. 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. 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.
