摘　　要：针对插电式串联混合动力汽车,提出了一种基于道路工况和整车功率需求分析的系统匹配方法。建立了混合动力系统的模型,并利用能量流图,对采用不同的能量管理策略时系统的能效进行仿真分析。结果表明,所提出的系统匹配方法可行,采用ON-OFF与负载跟随相结合的控制策略在改善车辆燃油经济性的同时,可提高系统关键部件的效率。A system matching method for plug-in series hybrid electric vehicle is proposed based on the a- nalysis on road conditions and vehicle power demand. A model for hybrid power system is built and a simulation a- nalysis on the energy efficiency of system under different energy management strategies is conducted by means of en- ergy flow diagram. The results show that the system matching method proposed is feasible, and the control strategy combining ON-OFF control with load following scheme can enhance the efficiency of key system components while improve the fuel economy of vehicle.
