摘　　要：功率分流装置是混联式混合动力汽车动力系统的核心部件,为了建立完整的整车仿真模型,实现混合动力汽车能量管理控制策略的优化设计,先对混联式混合动力汽车动力系统结构及功率分流装置的结构进行分析,并结合等效杠杆图分析功率分流模式,再针对混联式混合动力汽车复合功率分流装置特有的双行星齿轮机构,运用Simulink软件进行建模,进而得出四轴行星齿轮机构模型及其输入输出模型,为进一步研究混联式混合动力汽车复合功率分流装置的特性提供了重要的仿真试验基础。Power split device is the core component of parallel-series hybrid power system. In order to establish a complete vehicle simulation model and realize the optimal design of hybrid electric vehicle energy management control strategy, the structures of parallel-series hybrid power system and power split device are analyzed. The power split mode is analyzed combining with the equivalent leverage diagram. The model of dual planetary gear mechanism which is a unique structure for parallel-series compound power split device is set up by Simulink. Then the model of four-axis planetary gear mechanism and its input and output model are obtained. It provides an important simulation test basis for thrther studying characteristics of the parallel-series compound power split device of hybrid electric vehicle.
