Adaptive Cruise Control (ACC) in this embodiment is an automotive function that allows the vehicle cruise control system to adapt to traffic conditions by adjusting speed. A radar installed in front of the vehicle is used to detect whether there is a slower speed vehicle on the road on which the host vehicle is traveling. If there is a slower vehicle, the ACC system will slow down the vehicle and control the gap or time gap with the vehicle in front. This operation achieves autonomous deceleration or acceleration without driver intervention if the system detects that the leading vehicle is not on the path of travel of the host vehicle, which will accelerate the speed of the host vehicle back to the previously set speed. However, in actual use, if the user touches the brake pedal carelessly, or the user presses the brake pedal only for reducing the speed but does not actually want to exit the ACC, the user will immediately exit the control as long as the user presses the brake pedal ACC, and the control right of the vehicle is returned to the driver.

After the ACC is activated, a user steps on a brake pedal, the ACC enters a state to be activated, when brake parameters meet ACC activation conditions, the ACC can be automatically activated, the user does not need to manually press an ACC recovery key, user operation is reduced, and the use of the user is facilitated.
