Two-motor-drive electric vehicles (TMDEVs) have developed significantly in recent years. An important residual problem for this vehicle type is how to coordinate the operation of the driving motors for stable vehicle handling. In order to improve the turning stability of TMDEVs a control scheme, based on the target slip rate of driving wheels, is proposed to distribute the torque of both motors. First a dynamic model of TMDEVs and the tire model are described. Second a control strategy based on the target slip rate using a slide mode control method is specified. Then a dynamic analysis and simulation are conducted. The results show the proposed strategy can make the driving tires achieve the target slip rate and improve the turning stability of this vehicle.
