The Study on the Gear Shifting Strategy for 2-speed Planetary Transmission of Plug-in Electric Buses

摘要：

　　The shift logic of most automatic shift systems is based on two parameters-vehicle speed and throttle opening.In this paper,two-parameter shift schedule is applied for AT.The shift logic is on the basis of the optimal efficiency of the motor-transmission system.The model is built by Simulink/Stateflow and the simulation is carried up based on the driving cycle.Driving economy can be improved significantly after applying this shift logic for the power system.
