Abstract: As an energy-saving and environment-friendly vehicle, electric sanitation vehicle plays a vital role in urban life. The research object of this paper is a pure electric driven sanitation vehicle with multiple working modes. In this paper, the dual motor torque distribution strategy, the optimal efficiency shift strategy and the dual motor gearbox cooperative control strategy are formulated. The three control strategies can not only make the driving motor and operating motor work efficiently, but also give full play to the power of the system, so as to realize the economy of the whole vehicle The simulation analysis shows that the power and economy of the new control strategy are improved by 19.7% and 9.8% respectively compared with the original strategy.
