摘　　要： 探讨了一种具有两个机械端口和一个电气端口的电磁耦合无级变速系统,该系统不仅能实现无级变速功能,还具备车辆离合器,齿轮传动及启动电机等装置的功能。经对该变速系统的功率流模型的分析可知,基于无级变速系统的功率流数学模型的效率比常规级联式车用电传动系统高。能量分配优化方法在Matlab/Simulink仿真平台上应用于整车仿真,仿真结果表明这种无级变速系统的可行性。 An electromagnetic continuously variable transmission with two mechanical ports and one electrical port （consisting of two concentric permanent magnet machines and two invertors） is discussed. The transmission may replace the clutch, gearbox, generator and starter motor in a vehicle. According to the analysis of the power flow model of this transmission, the efficiency of this transmission is higher than that of the cascade system in vehicle. The optimization energy distribution method of the machines of this transmission is discussed and applied to the simulation of the vehicle with this transmission by matlab/simulink environment. The result of the simulation of the electromagnetic continuously variable transmission for vehicle shows that the application is feasible.
