英文摘要：

The structure and working principle of the in-wheel motor driving system of electric vehicle （EV） were analyzed. The single controller of XE164-FM was used to control two in-wheel motors according to the requirements about the coordination control of EV＇ s two motors. Therefore, it solved the controlling problem of delay and unreliability for CAN control of EV. Furthermore, the electronic differential and the controlling method of blushless DC motor were introduced. Moreover, the driving system of EV based on XE164 was designed. The results of experiment demonstrate that the method can coordinated control two in-wheel motors conveniently and effectively, and the feasibility and validity of the method are proved.
