Self-adaptive multi-stage braking control method for automatic emergency braking system

The invention discloses a self-adaptive multi-stage braking control method for an automatic emergency braking system and belongs to the technical field of traffic safety. In order to improve performance of an automatic emergency braking (AEB) system of an automobile and give consideration to safety and comfort in the emergency braking process, the invention provides a self-adaptive AEB control algorithm considering a road adhesion coefficient and a vehicle driving state. According to the AEB control algorithm, a safety time threshold value and the braking pressure of two-stage braking are determined by obtaining vehicle state information, front obstacle information and the road adhesion coefficient obtained through estimation; and when the brake triggering condition is met, a brake pressure control signal is sent to a brake executing mechanism, and therefore automatic emergency braking of the vehicle is achieved. According to the control algorithm, the AEB control strategy can be adjusted in a self-adaptive m
