摘　　要：设计了电磁功率分流混合动力系统,此系统采用双转子有刷电动机对发动机进行功率分流调节,可同时起到电磁离合器和无级变速箱的作用。在分析系统结构、工作原理和确定整车控制模式的基础上,基于NEDC循环利用整车仿真模型对控制模式进行了验证,并对整车动力性和经济性进行了分析。结果表明:针对电磁功率分流混合动力系统所涉设计的传动控制模式在各种工况下工作正常;采用该控制模式的整车0～100 km/h加速时间为12 s,满足最大爬坡度的指标,符合整车动力性设计的要求;整车的综合油耗为4.75 L/(100 km),与传统车相比节油率达到41.3%。A electromagnetic power-split （EMPS） hybrid electric vehicle was designed. This system with dual- rotor brush motor could be used to modulate the engine power flow, also can be used as electromagnetic clutch and CVT. The system configuration, working principle, the vehicle control mode and etc were analyzed. The control mode was tested under the NEDC based on the vehicle simulation platform. The dynamic and economic performances of the EMPS HEV were analyzed. The results noted that the designed vehicle control mode of the EMPS HEV worked properly under different cycles. The results also noted that the time from 0 km/h to 100 km/h was 12 s and climbing grade was bigger than 17~, these values were all satisfied with vehicle dynamic target. The average fuel consumption under the NEDC was 4.75 L/（ 100 km） , the fuel can be saved was 41.3% compared with the related conventional vehicle.
