摘　　要：针对后轮轮毂电机驱动电动汽车前轮转向,驱动轮差速控制问题进行了研究。根据机械差速器原理,分别基于PID控制理论和模糊控制理论,提出了自适应控制策略的电子差速控制器。通过Car Sim与Simulink联合仿真,选取电动汽车中等变车速蛇形试验工况和低、高速双移线工况对差速控制器的有效性进行了仿真验证,仿真结果表明:基于两种控制理论的电子差速控制器实现了基本相同的控制效果,有效保证电动汽车恒、变车速下的行驶稳定性。For the rear wheel in-wheel motor drive electric vehicle front wheel steering, driving wheel differential control problem is studied. According to the mechanical differential principle based on PID control theory and fuzzy control theory respectively, adaptive control strategy for electronic differential controller is proposed. Through the joint simulation of CarSim and Simulink, the double lane change experiment under low or high speed and the slalom experiment at medium variable speed as the experiment situation are selected, the effectiveness of differential controller is verified by simulation, the simulation results show that the electronic differential controller based on two kinds of control theory realized the basically same control effect, effectively guarantee the electric vehicle driving stability at constant or variable sDeed.
