摘　　要：以轮毂电机直接驱动的分布驱动式电动车为研究对象,为解决汽车转向行驶稳定性和主动安全性的问题,对其电子差速控制策略进行研究。将汽车转向时的横摆稳定性和车轮滑动率相结合,基于动力学计算转矩输出,使用模糊控制算法确定变量范围并设计出模糊控制器,采用双移线和方向盘角阶跃两种输入工况,通过CarSim搭建整车仿真联合模型,对两种电子差速控制策略的对比分析及仿真验证。结果表明,采用DYC+S控制策略比采用DYC+T控制策略的性能更加优越,提高了整车的驾驶性能。Regarding the dispersed electric automobile of actuating straightway of in-wheel motor as the object of study,so as to settle the question which the automobile are consistency and active security when it turn to travel,and carry out research on the electronic differential control tactics.when the automobile turn to travel,integrating the yaw consistency with wheel slip rate.While figure out the output of torque on account of kinetics,applying fuzzy control theory to confirm the range of variable,and de-sign fuzzy controller.The automobile emulation alliance model is establish via CarSim with two input cases.The two electronic dif-ferential control tactics are compared and testified.The result display that the property of DYC+S is superior to that of DYC+T,and the driving property of the whole vehicle is enhanced.
