摘　　要：文章对增程式混合动力汽车的工作模式进行了分析,并根据其运行模式,利用AMESIM软件搭建了增程式混合动力汽车的仿真模型。以在整个NEDC循环工况运行范围内电池的SOC基本不变的前提下尽量减少燃油消耗量为目标,对控制策略进行了仿真研究。研究结果表明,在较低速段采用纯电驱动,在较高速段进行充电,并将发动机工作点控制在其最佳油耗点附近,能够有效的改善整车的燃油经济性。The operating mode of the Extended-Range Electric Vehicles is analyzed in the paper,And according to the operating mode,the simulation model of the Extended-Range Electric Vehicles is constructed based on AMESIM.In order to reduce the fuel consumption as far as possible with lesser fluctuation of the battery SOC in the NEDC range,the control strategies of Extended-Range Electric Vehicles are studied.The results show it could reduce fuel consumption that the vehicle runs on electric energy of battery in lowwer velocity,and that it charges the battery with the engine running around the point of the least fuel consumption in higher velocity.
