Aiming at the negative effect of a hub motor on the ride comfort of an electric vehicle, a four-degree of freedom vibration plane model of hub motor electric vehicle is established, in order to study the influence of pas? sive suspension and active suspension on the pulse road ride comfort of the electric vehicle. An active suspension control strategy for hub motor electric vehicles is designed, and MATLAB/Simulink control simulation model is developed with the constrained state H∞ control method. The effects of no eccentricity, 10% eccentricity, and 20% eccentricity on the excitation of the hub motor are analyzed. The time history of pulse road vibration response of pas? sive suspension and active suspension of hub motor electric vehicle, as well as the ride comfort evaluation indexes of four cases, are compared. The results show that the eccentricity of the hub motor can produce vibration excitation on the electric vehicle, which not only affects the pulse road ride comfort but also affects the state feedback H∞ control.
