摘　　要：针对轮毂电机驱动式微型电动汽车的电子差速控制,考虑滑转率和轴荷转移的影响,提出了以驱动轮转矩为控制量,以电动汽车内外侧驱动轮滑转率均衡为控制目标,并考虑汽车转弯时轴荷转移的差速控制策略,进行了差速控制实车试验.试验结果表明,所采用的控制策略合理,控制器能够较好地协调2后驱动轮转矩,实现了汽车电子差速控制.A new control strategy of electronic differential system（EDS）is proposed with driving wheel torque as control variable and slip rate equilibrium of two driving wheels as control objective based on mini electric vehicle with in-wheel motors.The experiments have been done in steering mode based on the vehicle prototype.The results show that the control strategy is reasonable,and the controller can effectively accomplish differential control by coordinating the torque of two driving wheels.
