基于ADVIOSR软件，对混合动力汽车仿真系统进行二次开发，建立某特定布置形式的复杂混合动力汽车整车仿真模型和相关控制策略模型，并通过循环工况仿真分析汽车的燃油经济性和动力性。

英文摘要：

The simulation system of HEV （hybrid electric vehicle） w/~s redeveloped based on the simu- lation mechanism of ADVISOR. The simulation model of complex HEV with specific arrangement was established, and so was the related controlling strategy model. The fuel economy and power per- formance of the vehicle were analyzed through driving cycle simulation. The results provide a theoret- ical basis for optimized design of HEV powertrain assembly.
