摘　　要：分析了并联式液压混合动力系统功率密度大和城市行驶工况制动频繁的特点,综合考虑车辆载荷以及驱动方式对再生制动性能的影响,提出了一种基于安全制动的再生制动控制策略,采用后向建模方法建立了液压混合动力汽车仿真模型,进行了典型循环工况的再生制动仿真研究。仿真结果证明了所提出的再生制动控制策略和系统模型的正确性与适用性,在确保制动安全性的前提下高效地回收制动动能。Based on the analysis of the braking characteristics in the city drive cycle and high power density of hydrostatic drive hybrid vehicles, considering the effects of vehicle load weight and propulsion mode on regenerative braking performance, a regenerative braking control strategy for parallel hydraulic hybrid vehicles （PHHV） was proposed. A backward simulation model of PHHV was built with numerical modeling and theoretical modeling methods. Hydraulic regenerative braking was researched under typical driving cycles using the backward simulation model for PHHV and the results show that the control strategy and the models are accurate and applicable, and the braking energy under the premise of safety brake can be regenerated effectively.
