What does the ACC adaptive cruise control system mean?
2 Answers
ACC adaptive cruise control system refers to an intelligent automatic control system, which is developed on the basis of the existing cruise control technology. Working principle: During vehicle driving, the distance sensor (radar) installed at the front of the vehicle continuously scans the road ahead, while the wheel speed sensor collects the vehicle speed signal. Maintaining a safe distance: When the distance to the vehicle in front is too small, the ACC control unit can coordinate with the anti-lock braking system and the engine control system to appropriately brake the wheels and reduce the engine's output power, ensuring that the vehicle always maintains a safe distance from the vehicle ahead.
The ACC adaptive cruise system is like giving your car a brain—it automatically follows the lead car's pace on highways. Unlike traditional cruise control, which only maintains a set speed, ACC uses radar or cameras to monitor the distance and speed of vehicles ahead in real time. If the car in front slows down or another vehicle cuts in, the system adjusts your speed to maintain a safe gap and can even apply the brakes automatically. This technology is a real stress-reliever, especially on long drives where rear-end collisions are a constant worry. However, it's not foolproof—it may fail in heavy rain, fog, or on excessively curved roads, so I recommend drivers always stay alert. Overall, ACC makes driving smarter and safer, and it works even better when paired with a lane-keeping system.
