For differential problem of four wheel drive inwheel motor electric vehicle during steering process, the electronic differential control has been studied. The electronic differential control strategy was designed, and the differential reference kinematic model was established. According to the advantages that the four wheel drive torque of the four wheel inwheel motor electric vehicle can be independently control, the four wheel drive torque was allocatedreasonably through the drive torque distributor, which could achieve the actual wheel speed tracking reference wheel speed. The electronic differential system model of the four wheel inwheel motor electric vehicle was established in Matlab/Simulink. The model was verified through the cosimulation of CarSim and Matlab/Simulink. The results showed that the electronic differential control strategy could effectively realize four wheel differential during steering process and improve the handling stability of electric vehicle.
