What is ACC in a car?
1 Answers
ACC stands for Adaptive Cruise Control. Here is a detailed introduction to the adaptive cruise system: 1. The Adaptive Cruise Control system is an intelligent automatic control system developed based on existing cruise control technology. The adaptive cruise system uses low-power radar or infrared beams to determine the exact position of the vehicle ahead. If it detects that the preceding vehicle is slowing down or a new target is identified, the system sends execution signals to the engine or braking system to reduce the vehicle's speed, maintaining a safe distance between the vehicles. 2. When controlling the vehicle's braking, the car's Adaptive Cruise Control system typically limits the braking deceleration to a level that does not affect comfort. When greater deceleration is required, the ACC control unit emits audible and visual signals to alert the driver to take active braking measures. When the distance to the preceding vehicle increases to a safe distance, the ACC control unit adjusts the vehicle to travel at the set speed. 3. ACC can engage in cruise control at relatively low speeds, making it suitable not only for highway conditions but also for urban traffic, alleviating concerns about stop-and-go traffic. The car's sensors monitor the driving conditions of both the preceding vehicle and the host vehicle. After calculation and judgment by the ECU, commands are sent to the actuators to determine the vehicle's driving state—whether to accelerate, decelerate, or disengage from cruise control.
