What does ACC mean on the bus?

AdaptiveCruiseControl system, also known as intelligent cruise control system, or ACC system for short, is a new generation of driver-assisted driving system developed on the basis of traditional cruise control.

It organically combines the automatic cruise control system CCS with the forward collision warning system FCWS. ACC not only has all the functions of automatic cruise, but also can monitor the road traffic environment in front of the car through sensors such as on-board radar.

Extended data:

The adaptive cruise control system adds the function of preventing automobile collision, that is, it detects vehicles or objects in front or behind the vehicle through the electronic information system to keep the vehicle at a safe distance.

If it is found that the distance from the vehicle in front has reached an unsafe distance, you can reduce the speed by reducing the throttle opening, or perform automatic braking operation to avoid collision. Distance detection can be achieved by ultrasonic, laser beam, radar and other means. The German Mercedes-Benz S-Class 2000 was the first to be equipped with an adaptive cruise control system, and other companies followed suit.
