Abstract: | |
The shift schedule of automatic transmission plays an important influence on the dynamic performance, fuel economy and the driving range of the vehicle. In this paper we studied the optimizing dynamic performance shift schedule for the three-geared transmission-by-wire. The theoretical model for the optimizing dynamic performance shift schedule was analyzed and the shift point speed is gotten under different accelerator pedal opening. The curve of optimizing dynamic performance shift schedule is developed which could improve the performance of electric vehicle, so as to achieve the purpose of saving energy and increasing the driving range. |
