Abstract
A regenerative braking control strategy based on accelerator pedal travel is proposed for electric vehicle. When the accelerator pedal travel exceeds a certain threshold value, the regenerative braking torque of motor is calculated with fuzzy control algorithm and the process of engine drag braking is simulated. Then the models for motor and battery are created, a dSPACE hardware-in-the-loop comparative simulation is conducted on both the control strategy proposed and that without engine drag braking with the signal of acceleration pedal travel as input. The results show that with the control strategy proposed, the motor torque can well follow the driver's operation requests and the engine drag braking can recover a certain amount of energy.
