What does ACC on the dashboard mean?
2 Answers
ACC on the dashboard refers to the Adaptive Cruise Control system in a car, which consists of: 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 are: 1. Maintaining the vehicle's longitudinal movement, and when there is a collision risk, the vehicle will alert the driver and perform active braking intervention; 2. When the distance to the vehicle ahead is too small, the ACC control unit can coordinate with the anti-lock braking system and engine control system to apply appropriate braking to the wheels, ensuring the vehicle maintains a safe distance from the vehicle ahead.
I have been driving for ten years, and when ACC appears on my dashboard, it mainly refers to the Adaptive Cruise Control system. This system automatically adjusts the vehicle speed to maintain a safe distance from the car ahead, making it particularly suitable for long-distance driving. When I get on the highway, after activating ACC and setting the target speed, the vehicle will adjust acceleration or deceleration based on radar or camera detection of the car ahead, making my drive much easier and reducing fatigue. However, it's important to note that ACC is not fully autonomous driving; adverse weather conditions like heavy rain or fog can reduce sensor accuracy, so I must always be ready to take over the steering wheel. Additionally, the location of ACC operation buttons may vary across different car models, usually found on the steering wheel or center console—it's best to refer to the manual to learn how to use it before starting. Safety is the top priority; ACC is only an assistive driving feature and cannot replace attention. Ensure the system is well-maintained to prevent malfunctions.
