Abstract：In order to solve the problems of handling stability reduction due to redundancy of control freedom degree of the in-wheel drive electric vehicle,we designed a kind of integrated vehicle driving torque control system which can make electric vehicle adapt to straight-line traction and steering based on logic threshold value theory.The control system considers the effects of axle load transfer,centripetal force and tire side slip while the vehicle is moving to achieve the steering differential control,so that the vehicle can be driven on the ideal road according to drivers expectation.And the influences of the undesired yaw moment can be eliminated to improve handling stability of vehicle in the course of straight-line traction by conducting torque coordination control over driving motor.Simulation results show that the proposed torque control method can improve the control performance of in-wheel drive electric vehicle.
