摘　　要：提出了电动轮旋转动力学方程和对驱动电机采用转矩指令控制及车轮转速随动的方法,实现电动轮系统的自适应差速。进行了转向行驶、路面不平及不同车轮半径等工况的道路试验,试验结果表明:电动轮汽车在各种工况下都能保持良好的差速性能,具有自适应差速特性。An in-wheel motor rotation dynamic equation, a torque instruction control for drive motor and a wheel speed follow-up technique are proposed to realize the adaptive differential of the in-wheel motor EV. A road test on three working conditions （cornering, driving on rough road and driving with unequal-radius wheels） is also conducted. The test results show that in-wheel motor EVs possess adaptive differential characteristics and can maintain good differential performance under various driving conditions.
