Shift Strategy Development for Electric Bus

This paper studies the shifting strategy based on an electric bus. According to the development performance requirements of the bus, a dynamic shifting strategy and an economical shifting strategy are formulated respectively. Among them, the dynamic shifting strategy is mainly based on the principle of maximum acceleration to formulate corresponding shifting strategy, and the economical shifting strategy is mainly formulated based on the test data of the motor bench and the characteristics of the vehicle speed and efficiency curve under different accelerator pedal depths. Finally, build an AVL CRUISE vehicle simulation model to simulate and analyze the shifting strategy of the electric bus and a test platform for testing. Simulation and test results show that the proposed shifting strategy is feasible.
