Abstract: |
The invention relates to a brake energy feedback control method of electric vehicle, wherein it adjusts the front axle hydraulic brake force Fhf, the back axle hydraulic brake force Fhr, and the motor brake force Fm, that receiving the pressure signal from the brake main cylinder; if ABS works, the motor brake force Fm=0, transferring the Fhf and Fhr to the ABS to be adjusted; if ABS not works, based on if the real brake force Fba meets the brake threshold value F, the sliding rate threshold value S, and the motor torque limit, adjusting, until the brake pedal is released, ending the brake. The invention can avoid dead clamped wheel without road recognition, to obtain high energy feedback efficiency. |
