What is the ACC function in sedans?
2 Answers
ACC in sedans stands for Adaptive Cruise Control. The functional components of ACC include: 1. Radar sensor; 2. Electronic control unit; 3. Cruise control switch; 4. Speed setter; 5. Distance setter; 6. Status display; 7. Alarm. The functions of ACC in sedans are: 1. Maintaining longitudinal vehicle movement, where the vehicle alerts the driver and performs active braking intervention in case of collision risks; 2. When the distance to the vehicle ahead is too small, the ACC control unit coordinates with the anti-lock braking system and engine control system to apply appropriate braking to the wheels, ensuring the vehicle always maintains a safe distance from the vehicle ahead.
The ACC function in cars stands for Adaptive Cruise Control, which is different from regular cruise control. Having driven for so many years, I particularly appreciate its ability to automatically adjust speed on highways and maintain a safe distance from the vehicle ahead. If the car in front slows down, my car will also decelerate without me needing to constantly press the accelerator or brake. I remember one time on a long trip when traffic was jammed and frustrating, but turning on ACC made it much easier because the system reacted faster than I could, reducing the risk of rear-end collisions. However, this system relies on sensors like radar or cameras, and if they get dirty or in rainy weather, its performance becomes less stable, so it's important to regularly clean the front of the car. I think ACC significantly enhances driving comfort, especially for frequent travelers, reducing fatigue by nearly half. It's one of the highlights of modern cars.
