What does ACC mean in a car?
2 Answers
In cars, ACC stands for Adaptive Cruise Control. The Adaptive Cruise Control system is an intelligent automatic control system developed from the existing cruise control technology. During vehicle operation, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects vehicle speed signals. Here is relevant information about ACC: 1. ACC working principle: When the distance to the vehicle ahead becomes too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to apply appropriate wheel braking and reduce engine power output, maintaining a safe distance from the vehicle ahead. 2. ACC usage conditions: The Adaptive Cruise Control system typically activates when the vehicle speed exceeds 25km/h. When speed drops below 25km/h, the driver needs to take manual control. Through system software upgrades, the Adaptive Cruise Control system can achieve 'Stop & Go' functionality to handle frequent stopping and starting situations in urban driving.
ACC in a car generally refers to Adaptive Cruise Control. It is a driving assistance system that uses radar or cameras to monitor the distance and speed of vehicles ahead, automatically adjusting your speed to maintain a safe following distance. More intelligent than traditional cruise control, it reduces manual intervention, especially on highways or in traffic jams, enhancing driving comfort. The first time I used ACC was on a congested highway—it automatically slowed down, making my drive much easier and helping avoid rear-end collision risks. Remember to ensure the system is functioning properly; otherwise, it may fail and pose safety hazards.
