【Abstract】 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.更多还原
