摘　　要：为提高整车经济性,提出一种单行星排混联式混合动力系统,并以重型商用牵引车为研究对象,根据动力性指标开展了整车部件关键参数设计,以发动机最优控制为基本原则,制定了整车顶层工作模式及子工作模式的切换规则。最后,利用Simulink编写模式切换策略控制程序,基于Cruise建立整车经济性仿真模型并进行联合仿真,结果表明,采用该混合动力构型的车辆在快运工况和煤炭运输工况下的燃油消耗量均低于传统燃油车。To improve vehicle economy,this paper proposes a single planetary array hybrid system.Taking the heavy commercial tractor as the research object,the key parameters of automotive components are designed according to power performance indicators.The optimal control of the engine is taken as the basic principle,and the switching principles of the top-level working mode and sub-working mode of the vehicle are formulated.The mode switch strategy control program is written using Simulink,and the vehicle economic simulation model is established using Cruise.The results show that fuel consumption of the hybrid vehicle is lower than that of the traditional fuel vehicle in the fast transportation and coal transportation condition.
