The invention relates to a tracking anti-skid control method of an electric vehicle, the electric vehicle comprises a front wheel speed sensor, a rear wheel speed sensor, an accelerator position sensor and a control unit, and the control unit is connected with the front wheel speed sensor, the rear wheel speed sensor and the accelerator position sensor. When a slip difference value is generated between a front wheel and a rear wheel of the electric vehicle, the control unit judges whether the slip difference value reaches a slip difference rising threshold value or not, if yes, the control unit executes a tracking anti-slip control state, and the current torque value is used as a torque reference value, and a tracking anti-slip algorithm built in the control unit is used for tracking the torque reference value. And subtracting a proportional control quantity, an integral control quantity and an accelerator correction quantity from the torque reference value to generate a tracking anti-skid torque command, and controlling a power motor according to the tracking anti-skid torque.

    本发明为一种电动车的循迹防滑控制方法,该电动车包含一前轮速感测器、一后轮速感测器、一油门位置感测器及一控制单元,该控制单元连接该前轮速感测器、该后轮速感测器及该油门位置感测器。当该电动车的前轮与后轮产生一滑差值时,该控制单元判断该滑差值是否达一滑差上升门槛值,若是,该控制单元执行一循迹防滑控制状态并以当下的扭力值为一扭力基准值,再借由该控制单元内建的一循迹防滑演算法,将该扭力基准值减掉一比例控制量、一积分控制量及一油门补正量,以产生一循迹防滑扭力命令,再根据该循迹防滑扭力控制控制一动力马达。
