  • A pure electric vehicle driven by dual motors is taken as the research object and the driving scheme of the driving motor is improved to increase the transmission efficiency of existing electric vehicles. Based on the architecture of the transmission system, we propose vehicle performance parameters and performance indexes of a pure electric vehicle, a time-sharing driving strategy of dual motors. First, the parameters of the battery, motor, and transmission system are matched. Then, the electric vehicle transmission model is built in Amesim and the control strategy is designed in Simulink. With the optimization goal of improving the vehicle’s dynamic performance and driving range, the optimal parameters are determined through analysis. Finally, the characteristics of the motor are tested on the bench. The results show that the energy-saving potential of the time-sharing driven double motor is higher, and the driving mileage of the double motor drive is increased by 4%.
