摘　　要：为提高混合动力汽车的动力性和燃油经济性,简化驱动系统的结构,提出了一种新型多模式驱动的增程式电动汽车驱动系统.文中分析了该系统的各个工作模式及功率流分配;通过台架实验获得了发动机、电机、电池等的工作性能,在Matlab/Simulink环境下建立了关键动力元件(如发动机、主电机、辅助电机和蓄电池)及整车的仿真模型,并对该系统进行了动力性能和燃油经济性能仿真分析.结果表明,相对于Volt系统,文中提出的驱动系统的动力性明显改善,最高车速提高了37.5%,燃油消耗率降低了24.8%.In order to improve the dynamic performance and the fuel economy of HEV（Hybrid Electric Vehicle）and to simplify the structure of driving system,a novel multi-mode driving system is proposed for REEV（RangExtended Electric Vehicle）.Then,all the operating modes and the power flow distribution of the proposed system are analyzed,and the performances of engine,motor and battery are obtained through a bench test.On this basis,a dynamic model of such key power components as engine,main motor,auxiliary motor and the battery and a vehicle simulation model are established by using the Matlab / Simulink software,and the dynamic performance and the fuel economy of the vehicle are simulated.The results show that,as compared with the Volt system,the proposed system improves the dynamic performance significantly,increases the maximum speed by 37.5% and decreases the fuel consumption by 24.8%.
