摘　　要：为了使发动机工作在最佳效率区并可在车辆减速过程中回收制动能量,以提高车辆的燃油经济性,对并联式静液传动混合动力车辆(PHHV)主要部件的设计准则进行了研究,结合静液传动能量再生系统功率密度大的特点,分析了静液传动混合动力车辆在城市行驶工况下的制动特征,针对PHHV提出了一种新的再生制动控制策略.仿真和试验结果表明:所设计的驱动系统参数匹配较为合理,液压再生制动控制系统可以合理地分配液压再生制动转矩和传统摩擦制动转矩的比例关系,在确保制动安全性的前提下高效地回收制动动能.To improve the fuel economy of parallel hydraulic hybrid vehicles （PHHV） by operating the engine in the optimum efficiency range and making use of regenerative braking during deceleration, the design criteria of important components for PHHV were researched. Based on the analysis of braking characteristics of PHHV in the city drive cycle and the high power density of hydraulic transmission, a new regenerative braking strategy tai- lored specially for PHHV was proposed. Based on the Matlab/Simulink software platform, the performance sim- ulation was accomplished under a selected driving cycle. Results show that the parameters of propulsion system are reasonably matched; the proposed hydraulic regenerative braking strategy can reasonably distribute the hydraulic regenerative braking torque and traditional friction b energy of the vehicle under the premise of safe braking and raking torque, which effectively regenerates braking improves the braking performance.
