The automobile braking is an important means for ensuring the running safety of the automobile, and in the running process of the automobile, the deceleration intention of a driver can be transmitted to surrounding vehicles and pedestrians through a brake signal lamp to make judgment in advance so as to avoid rear-end collision accidents. The vehicle braking can be divided into general braking and emergency braking, the braking strength of the general braking is smaller, the vehicle is decelerated slowly, and the rear vehicle can generally deal with the braking signal of the front vehicle in time when seeing the braking signal; the emergency braking has the advantages that the braking strength is high, the vehicle is decelerated quickly, and after the rear vehicle sees the braking signal of the front vehicle, enough time and enough braking strength are needed to ensure that the running speed of the vehicle is reduced, so that the rear-end collision accident is avoided. The brake signal lamp in emergency braking is different from the brake signal lamp in general braking, so that the rear vehicle can be timely reminded to act in advance, and rear-end collision is avoided; however, in the existing automobile braking system, the common braking and the emergency braking are not distinguished, and the same braking signal lamp is adopted, so that great potential safety hazards exist, and particularly in the process of high-speed running of the automobile, once the front automobile is braked emergently, the possibility of rear-end collision of the rear automobile is high.

In the patent application, the emergency braking reminding delay function is not provided, if the front vehicle lights an auxiliary brake lamp and the vehicle speed is reduced to a certain value, the brake pedal is released and the vehicle is accelerated to run, the controller exits the emergency braking mode, and at the moment, the rear vehicle is also in possibility of rear-end collision because the vehicle speed of the front vehicle is not yet found. 3.
