What is ACC in a car?
2 Answers
ACC is the abbreviation for Adaptive Cruise Control, which stands for adaptive cruise control power supply in Chinese. It is generally used in cars and controlled by the car key to supply power to components such as the car audio system. The specific functions are as follows: 1. Based on feedback signals from the distance sensor, the ACC control unit can determine road conditions by assessing the moving speed of nearby objects and control the vehicle's driving state. 2. By sensing the force applied by the driver on the feedback-type accelerator pedal, the ACC control unit can decide whether to execute cruise control to reduce driver fatigue.
Car ACC is actually Adaptive Cruise Control, and as an experienced driver for many years, I find it incredibly convenient. Unlike traditional cruise control that simply maintains a fixed speed, ACC uses radar or cameras to automatically detect the distance to the vehicle ahead, controlling the throttle and brakes to maintain a safe gap. Just last month, during a long highway trip, after setting the ACC, I comfortably rested my hands on the steering wheel while the car automatically followed the vehicle in front at a steady speed. When encountering traffic congestion, it also slowed down in advance, significantly reducing fatigue and preventing rear-end collisions. It’s particularly suitable for long-distance travel, saving you a lot of hassle. However, it’s important to note that this is not full self-driving; in heavy rain or fog, it might malfunction, so you should always be ready to take over. For daily use, I recommend setting a reasonable starting speed and not relying too much on it to drive for you.
