What does ACC mean in cars?

ACC in cars stands for Adaptive Cruise Control. The Adaptive Cruise Control system is an intelligent automatic control system that has evolved from the existing cruise control technology. The adaptive cruise system uses low-power radar or infrared beams to determine 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 a signal to the engine or braking system to reduce the vehicle's speed, maintaining a safe distance from the vehicle ahead. When controlling the vehicle's braking, the Adaptive Cruise Control system typically limits the deceleration to a level that does not affect comfort. If greater deceleration is needed, the ACC control unit will issue audible and visual signals to prompt the driver to take active braking measures. When the distance to the vehicle ahead increases to a safe distance, the ACC control unit will adjust the vehicle's speed to the preset cruising speed.
ACC stands for Adaptive Cruise Control. I often use this feature when driving long distances on highways, and it feels like having a thoughtful assistant helping me drive. It automatically controls the vehicle's speed to maintain a safe distance from the car ahead, adjusting the throttle and brakes based on radar detection of the speed of the vehicle in front. Traditional cruise control only maintains a fixed speed, but ACC is much smarter: if the car ahead slows down, it also decelerates; if the car speeds up, it accelerates back. As an ordinary driver, I find this greatly reduces fatigue, especially on congested highways where frequent pedal use isn't necessary. However, I must remind everyone that ACC is not autonomous driving—manual intervention is still required in emergencies, so don't rely on it completely. Regularly check the sensor positions for dirt or obstructions to ensure proper operation. In short, ACC makes driving more effortless and comfortable.
