摘　　要：针对轮毂电机驱动的电动汽车的相关转向问题,通过利用机械差速器的原理,提出了诸如“差速不差力”,甚或“自适应”的相关原理,即通常所说的电子差速器。最终通过对两侧驱动电磁、电机转矩的控制,进而达到对驱动电机差速的控制。也就在研发的过程当中,通过MATLAB的仿真技术,最终证明了该设计的可行性。Aiming at the related steering problems of electric vehicles driven by in-wheel motors,by using the principle of mechanical differential,this paper puts forward some related principles such as udifferential speed without differential fbrce^^or even u self adaptationM,which is commonly called electronic differential.Finally,through the control of driving electromagnetism and motor torque on both sides,the differential speed of the driving motor can be controlled.In the process of research and development,the feasibility of the design was finally proved by the simulation technology of MATLAB.
