Energy recovery method based on automatic emergency braking of vehicle

The invention discloses an energy recovery method based on automatic emergency braking of a vehicle, and belongs to the technical field of automotive electronics. Comprising the following steps that energy generated in the vehicle braking process is recycled through an energy recycling device, and the recycled energy is stored; the method comprises the following steps: identifying and storing facial expressions and some micro-actions of a driver through a visual camera mounted on a vehicle, acquiring a brake signal through a brake pedal sensor, and analyzing the brake signal twice; the control unit carries out analysis and comparison according to the braking strength signals generated by two times of analysis, and controls the pressure of the wheel cylinder; and the working state and the energy storage condition of the energy recovery device are monitored in real time through the energy recovery monitoring and feedback device. The energy recovery rate is increased on the premise that the safety of emergency b
