Research on the Shift Schedule of Dual Clutch Transmission for Pure Electric Vehicle

The shift schedule is one of the core contents of main control logic of pure electric vehicle drive control system. With the right shift schedule, the vehicle can obtain good power performance and fuel economy. A shift schedule of dual clutch transmission (DCT) for pure electric vehicle based on powertrain coordination control is presented in this paper. Based on conventional vehicle shift schedule, the DCT shift schedule of pure electric vehicle drive system with powertrain coordination control is analyzed in detail. In order to verify the effectiveness of the shift schedule, some simulations are carried out. The results show the shift schedule of dual clutch transmission for pure electric vehicle based on powertrain coordination control can improve the vehicle power performance.
