Abstract:A fuzzy control strategy based on hydraulic regenerative braking system for the pure electric vehicle was proposed. Comprehensive considering the influences of the depth of the brake pedal, accumulator pressure, battery SOC value on the vehicle braking force distribution,the regenerative braking force was reasonably allocated. Under the premise of ensuring brake safety, the energy was recovered as far as possible, and the energy utilization efficiency was improved. The simulation results show that the fuzzy control strategy based on the hydraulic regenerative braking system improves the energy efficiency of the vehicle energy storage system, reduces the energy loss caused by the automobile brake, and improves the motor efficiency.
