What does ACC mean on a car?

[LaClaire]

ACC in a car refers to Adaptive Cruise Control. Here are the specific details about Adaptive Cruise Control: 1. The Adaptive Cruise Control system is an intelligent automatic control system developed on the basis of the existing cruise control technology. The adaptive cruise system uses low-power radar or infrared beams to obtain the exact position of the vehicle ahead. If it detects that the vehicle ahead is slowing down or a new target is detected, the system sends an execution signal to the engine or braking system to reduce the vehicle speed, maintaining a safe driving distance between the vehicle and the one ahead. 2. When controlling vehicle braking, the Adaptive Cruise Control system typically limits the braking deceleration to a level that does not affect comfort. When greater deceleration is required, the ACC control unit will issue audible and visual signals to notify the driver to take active braking measures. 3. When the distance to the vehicle ahead increases to a safe distance, the ACC control unit controls the vehicle to travel at the set speed.
