摘要
分析了并联式混合动力电动汽车(PHEV)动力总成的构成及主要传递参数,阐述了电力辅助控制策略以及控制逻辑的具体实现,建立了PHEV动力总成各子系统包括发动机、电机和电池等的仿真模型,利用建立的仿真软件进行了控制策略及其控制参数的仿真研究。仿真结果表明,电池特性及发动机运行参数对整车的性能有较大的影响,根据不同的控制要求,调整相应的控制参数值,可以达到改善整车性能的目的。
The paper analyzes the construction and main parameters of a parallel hybrid electric vehicle (PHEV) and explains the power auxiliary control strateg y and the specific realization of the control logic. Then, simulation models for the powertrain subsystems of PHEV, which include engine, electric motor and bat tery, are built. Finally, the simulation study on the control strategy is perfor med by the simulation software developed. The simulation result shows that the c haracteristics of battery and the parameters of engine have great effect on vehi cle performance. According to the different control requirements, the vehicle pe rformance can be improved by adjusting the corresponding control parameters.
