What does ACC adaptive cruise control mean?
2 Answers
ACC adaptive cruise control is an automatic control system whose function is: when the distance between the car and the vehicle in front is too small, the ACC control unit coordinates with the anti-lock braking system and the engine control system to apply appropriate braking to the wheels and reduce the engine's output power, ensuring that the vehicle maintains a safe distance from the vehicle ahead. The automatic control system includes a radar sensor, digital signal processor, and control module. Its working principle is: the system uses low-power radar or infrared beams to determine the exact position of the vehicle in front. 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's speed, thereby maintaining a safe driving distance from the vehicle ahead.
ACC adaptive cruise control is a high-tech feature I frequently use while driving. It automatically adjusts my vehicle's speed based on the preceding car's speed on highways, maintaining a safe distance. For example, if the car ahead slows down, it decelerates accordingly; if the car speeds up, it accelerates—you just need to steer. I find it particularly relaxing on long drives, reducing foot fatigue and accident risks. Especially in traffic jams, it gradually follows the car in front to a stop without requiring frequent braking or acceleration. However, it's not suitable for sharp turns or chaotic road conditions, so I recommend practicing to familiarize yourself with the system's characteristics. Overall, ACC enhances driving comfort and safety, making it one of the essential modern vehicle assists.
