摘　　要：从整车动力性和经济性角度出发,对电动汽车电机传动系统参数匹配进行了探讨。根据对电机功率的需求,提出了电动汽车电机传动参数的选择和匹配的方法。分析了扩大电机恒功率系数对整车动力性能和经济性能的影响,通过对目标车型的仿真,优化了电机的基本参数。最后通过实车验证该方法的合理性和可行性。From the angle of the vehicle performance and fuel economy, the parameter matching of motor drive system for electric vehicles was discussed in this paper. The selection and matching method of motor drive system were given according to the demand for motor power. The influence of the constant power expansion coefficient on the power and economic performance of vehicle was analyzed, the basic parameters of the motor was optimized through to the target model simulation. Finally the rationality and feasibility of the method was validated by a real vehicle.
