In view of the problems such as large mode-switching impact and unreasonable torque distribution in the dual-motor coupled drive system of electric vehicles, this paper proposes a dynamic coordination control method for the dual-motor coupled drive system of electric vehicles. By establishing a dynamic model, designing multi-mode torque dynamic allocation rules and multi-mode switching coordination control algorithms, the comprehensive effects of improving the vehicle's economy, dynamic response and smooth mode-switching are verified under common vehicle operating conditions and power conditions.
