摘　　要：以轮式驱动电动汽车为研究对象,重点研究轮式驱动电动汽车的驱动系统,建立电机和轮胎的数学模型。以直流电机等效电路为基础建立电机数学模型,采用普遍参考的统一半经验指数建立轮胎模型。使用MATLAB软件进行动态仿真,得出电机转矩和轮胎侧向力、纵向力曲线,仿真结果表明模型正确,与理论分析相符。Taking wheel driven electric vehicle as research object, we focus on driving system of wheel driven electric vehicle, and the mathematical models of motor and tyre are established. The motor model is built based on DC motor equivalent circuit and the mathematic model of the tyre is a semi-empirical model. Dynamic simulation is performed by MATLAB and the curves of motor torque, tire lateral force and tyre longitudinal force are obtained. The simulation results show that the mathematical models are correct and the models are consistent with the theoretical analysis.
