Role of ACC

The automatic adaptive cruise control power supply is controlled by the car key, which supplies power for some equipment such as car stereo. ACC can generally enter the cruise at low speed. Besides high-speed road conditions, it can also be applied to urban road conditions, so don't worry too much about the stop-and-go state of traffic jams. According to the distance and speed between the preceding vehicle and the vehicle, the sensor radar of the vehicle will give instructions to the accelerator, brake and gear of the actuator after calculation and judgment by ECU, so as to determine its driving state, whether to accelerate or decelerate, or to quit cruising.
