What does ACC mean on the steering wheel of a car?

1, ACC: it means AdaptiveCruiseControl system, and its English name is adaptive cruise control, abbreviated as ACC.

2. The adaptive cruise control system is mainly composed of adaptive cruise control system sensor, adaptive cruise control system controller, engine management controller, electronic throttle actuator and ABS/ESP brake actuator. Smart cars equipped with adaptive cruise control system can distinguish whether there are bicycles, cars or pedestrians approaching the vehicle through radar and computer, and control the driving state of the vehicle according to the road conditions, completely or partially replacing the driver's operation.

3. When the vehicle is running, the distance sensor radar installed at the front of the vehicle constantly scans the road in front of the vehicle, while the wheel speed sensor collects the speed signal. When the distance between the vehicle and the preceding vehicle is too small, the ACC control unit can cooperate with the anti-lock braking system and the engine control system to properly brake the wheels and reduce the output power of the engine, so that the vehicle and the preceding vehicle can always keep a safe distance.
