一种混合动力汽车动力驱动系统架构及其控制方法研究

The structure and control method research of power train system on hybrid electric vehicles

为了方便整车总布置,同时提高整车动力系统效率,对动力系统设计了一套布置合理的架构;为了充分发挥混合动力公交车的动力性及经济性优势,让发动机、电机、变速箱、离合器等各部件相互协调工作提高整车行驶安全性,同时又兼顾保护电池的功能,特开发了一套科学合理的控制策略。

In order to facilitate the general arrangement,and at the same time,improve the efficiency of power train system,design a set of layout reasonable framework for the power train system;In order to give full play to the hybrid bus,the dynamic performance and economic advantage,let the engine,electric motor,gearbox,clutch and so on various parts coordination work to improve the vehicle running safety,as well as protect the function of the batteries,especially developed a set of scientific and reasonable control strategy.
