To analyze vibration performance of electric vehicle with switched reluctance motor, a filter white noise method was used to describe the road excitations of front wheel and rear wheel based on time correlation between front wheel and rear wheel. A linear model was applied to describe the vertical excitation of switched reluctance motor, and in-wheel motor electric vehicle vibration was determined by a six degree of freedom plane system of vehicle. In the urban driving situation of B grade road and speed range, electric vehicle vibration was studied by simulation analysis under the action of road and switched reluctance motor. The results show that low speed has a big influence on the wheel accelerations and wheel dynamic load, while high speed has a great influence on seat accelerations and suspension dynamic deflections under the presence of the same directional motor eccentricity condition of the front wheel and rear wheel.
