What is ACC in a car?
1 Answers
ACC stands for Adaptive Cruise Control in automobiles. The following is a detailed introduction to the adaptive cruise system: 1. The Adaptive Cruise Control system is an intelligent automatic control system developed based on the existing cruise control technology. The adaptive cruise system uses low-power radar or infrared beams to obtain the precise 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 speed, maintaining a safe driving distance between the vehicles. 2. When controlling vehicle braking, the Adaptive Cruise Control system typically limits the deceleration to a level that does not affect comfort. When greater deceleration is required, the ACC control unit will issue audible and visual signals to prompt the driver to actively apply the brakes. When the distance to the preceding vehicle increases to a safe range, the ACC control unit adjusts the vehicle to travel at the preset speed. 3. ACC can engage in cruise mode at relatively low speeds, making it suitable not only for highway conditions but also for urban traffic, alleviating concerns about stop-and-go traffic congestion. The vehicle's sensors, based on the driving conditions of both the preceding vehicle and the host vehicle, send commands to the actuators after ECU calculation and judgment to determine the driving state—whether to accelerate, decelerate, or disengage from cruise control.
