摘　　要：控制策略是混合动力汽车(HEV)的关键技术,直接影响HEV整车性能。文章以整车动力性和燃油经济性为控制目标,分别设计了基于逻辑门限值的电力辅助控制策略和模糊逻辑控制策略,在CRUISE平台上搭建样车ISG混合动力汽车的模型,并分别在UDDS和NEDC 2种工况下进行仿真分析。仿真结果表明,与同类型传统燃油汽车相比,基于电力辅助控制策略和模糊逻辑控制策略的ISG型HEV的燃油经济性都有明显改善,模糊逻辑控制策略更为适合。The control strategy is the key technology for hybrid electric vehicle（HEV）,which directly affects the performance of the whole vehicle.In this paper,the vehicle power performance and fuel economy are the main control targets.The electric assist control strategy based on logic threshold and the fuzzy logic control strategy for ISG hybrid system were designed.Then the ISG-HEV model was built on the platform CRUISE and the simulation was conducted under the UDDS and NEDC operating conditions respectively.It is concluded that compared to the conventional fuel vehicle of the same type,both the electric assist control strategy and fuzzy logic control strategy have improved the fuel economy of the mild ISG-HEV,and the latter is more convenient with ISG parallel HEV.
