ISA型混合动力汽车的控制策略及性能仿真

Control Strategy and Performance Simulation of ISA HEV

在介绍了ISA(IntegratedStarterAlternator)轻度混合动力汽车结构及主要特点的基础上,着重分析了发动机和电机之间的能量匹配以及控制策略。通过实例,利用ADVISOR软件对传统车辆和改装后ISA型混合动力汽车进行仿真分析,结果显示:其燃油经济性和动力性得到大幅提高,污染排放得到有效提高,为该混合动车具体设计提供了理论依据。

After introducing the structure and main characteristics of a mild hybrid system based on ISA （Integrated Starter/ Alternator）, this paper analyses the energy flow management between engine and motor as well as the control strategy. In addition, the conventional vehicle and the ISA HEV retrofitted from conventional vehicle were simulated with ADISOR software, which provided the theoretical foundation for this HEV＇s specific design.
