In order to obtain drive control strategy for multi-motor drive system that take into account both lateral and longitudinal performance of the racing car and at the same time can reconcile the internal conflicts between different strategies. This paper first analyzes the possibility and advantages of coupling multiple control strategies, and discusses the applicability of sliding mode control in multiple control strategies. The drive control strategy is designed for the dual-motor independent drive system, a pedal analysis strategy is built to optimize the control of motor torque by accelerator pedal, the left and right motor torques are reasonably distributed through the electronic differential control strategy, the drive force is reasonably constrained using the traction control strategy, and the coupling is carried out according to the characteristics and logical relationships between the control strategies. Simulation and real-vehicle tests show that the coupled drive control strategies complement each other to further improve the dynamics, stability and handling of the racing car.
