| Abstract: | Electric vehicle is driven by electric motors and the motor' s efficiency has a direct impact on the vehicle economics. Based on the theory of vehicle dynamics, driving force distribution (DFD) is abstracted to a mathematic model taking the motor' s efficiency into account. The core of optimized DFD strategy is coefficient matrix which is calculated by complex- shape method in optimization theory. The DFD strategy increases efficiency of driving motor system and improves economics of vehicle. |
