摘　　要：针对纯电动汽车提出一种基于液压再生制动系统的模糊控制策略,综合考虑制动踏板深度、蓄能器压力、蓄电池SOC值等因素对再生制动力分配的影响,并对再生制动力进行合理的分配,在保证制动安全性的前提下,尽可能多地回收制动能量,提高能量利用效率。仿真结果表明:基于液压再生制动系统的模糊控制策略提高了整车能量存储系统的能量使用效率,降低了汽车因制动而带来的能量损失,提高了电动机工作效率。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 bra-king 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.
