控制策略是混合动力汽车的关键技术之一，直接影响整车的性能。在ISG混合动力系统中，发动机和电动机的扭矩耦合在一根轴上。本文详细分析了ISG混合动力系统的结构和基本要求。提出了一种基于ISG混合动力汽车的电动助力控制策略，并制定了模糊逻辑控制策略。基于Advisor软件建立了ISG混合动力系统控制策略的子系统模型，并对ISG混合动力系统的性能进行了仿真。结果表明，该控制策略合理，与常规车辆相比，其动力性和燃油经济性均有所提高。
The control strategy is one of the key technologies for hybrid electric vehicle, for it directly affects the performance of the whole vehicle. In ISG hybrid system, the torque from engine and motor are coupled at one shaft. The configuration and basic requirements of ISG hybrid system are analyzed in detail in this paper. An Electric Assist Control Strategy based on the ISG HEV is proposed and the Fuzzy Logic Control Strategy is formulated. Based on the software Advisor, the subsystem models of control strategy are established, and the performance of the ISG hybrid system is simulated. It concludes that the control strategy is reasonable, and the performance and fuel economy are better comparing with the conventional vehicle.
