摘　　要：按照设计要求,以TJ7100轿车为设计原型,针对ISG型混合动力电动汽车(HEV),使用Simulink建立了其动力系统的动态仿真模型,重点研究并制定了相应的电力助动控制策略。在ECE循环工况下对仿真模型进行了动力性和燃油经济性分析,为搭建动力总成试验平台提供了参考依据。结果表明,所制定的控制策略能有效地较低燃油消耗,使电池SOC值维持在一定的范围内。同时,仿真结果与实际情况基本相符,从而验证了所建仿真模型的正确性和合理性。Accordance to the design requirements,based on the design prototype of TJ7100,the power system dynamic simulation model of an ISG hybrid electric vehicle （HEV） was established using simulink focusing on the research and development of the corresponding electric assist control strategy. The analysis of dynamics and fuel economy of the model was carried out in the ECE cycle ,which provides a reference for setup of the powertrain test platform. The results showed that fuel consumption can be ef- fectively reduced by using the strategy developed with the SOC value of the battery maintaining in a certain scope. And the simulation results are basically in accord with the actual situation,which verifies the correctness and the reasonableness of the simulation model.
