The invention discloses a driving anti-skid control method for an extended-range electric vehicle. The driving anti-skid control method comprises the following steps that S1, the whole vehicle is driven to run; s2, the ASR judges the slip rate of the driving wheel; s3, whether the slip rate is higher than a threshold value or not is judged, if yes, the step S4 is executed, and if not, the step S5 is executed. The invention develops a filtering processing algorithm which is safer and more reliable and can improve the driving performance development efficiency of different vehicle types for the extended-range electric vehicle, starts from the safety of control interaction, drives the anti-skid control unit to be closely matched with the whole vehicle control unit, and starts from the control torque path of driving wheel anti-skid rotation. According to the method, an interaction control strategy and a specific filtering algorithm are designed based on a first principle of torque responsiveness of driving anti-skid, and different torque filtering algorithms are started in driving anti-skid activation and non-activation states, so that the safety and robustness of the driving anti-skid function are improved, and the development efficiency of the driving performance of the whole vehicle is improved.
