Adaptive cruise control (ACC) is an enhancement of conventional cruise control. ACC makes sure that your car moves at the same speed as the car in front of you. If the car in front of you slows down, ACC can match that speed. When the car in front of you moves out of your lane or speeds up faster than your set speed, your ACC lets your car go back to the speed you set.
How does it work?
Depending on the type of car you have, the controls will be different, but you will usually have to start by setting a cruising speed and a distance from the car in front of you.
Activation/Deactivation
The controls for most systems are on the steering wheel. You can also stop or speed up the car at any time by using the brake or gas pedal.
Choosing the pace
The +/- speed button lets you change the speed. You can also speed up normally until you reach the speed you want. Then you press a button to “remember” the speed in the ACC. Most ACC systems work at speeds as low as 25 mph.
Choosing how far apart
With an ACC system, you can set how far behind the car in front of you you want to be. ACC systems offer different options for the distance between cars, such as “short,” “medium, and “long. As traffic changes, you can change the setting whenever you want. Most driving should be done with a longer setting.
How does it work?
Like regular cruise control, ACC keeps your car going at the speed you set, as long as there is nothing in front of you. A sensor unit is added so that your car can tell how far away the cars in front of it are.
Sensors for speed and distance. ACC uses information from two sensors: a sensor that measures the distance to the car ahead and a sensor that measures your car’s speed to automatically speed up and slow down your car. The information from these sensors is used by ACC to change your speed and keep you at a certain distance from the car in front of you.
Radar-based systems: A look under the hood Let’s look at one type of ACC technology: ACC that uses radar. Some ACC systems send out radar waves that things in front of your car reflect back. ACC uses the distance, direction, and relative speed of the car and the radar reflection to figure out if the car is within the distance you set. ACC figures out where your car is going and then checks to see if any of the cars ahead are close enough.
