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.

    本发明公开了一种增程式电动汽车驱动防滑控制方法,包括以下步骤:步骤S1,整车驱动行驶;步骤S2,ASR判断驱动轮滑转率;步骤S3,判断滑转率是否高于阈值,若是则进入步骤S4,若否则进入步骤S5。本发明针对增程式电动汽车,开发了一种更为安全可靠,并且提高不同车型驾驶性能开发效率的滤波处理算法,从控制交互的安全性出发,驱动防滑控制单元与整车控制单元密切配合,从驱动轮防滑转的控制扭矩路径出发,基于驱动防滑的扭矩响应性第一原则,设计交互控制策略和具体的滤波算法,在驱动防滑激活和非激活状态下,启用不同的的扭矩滤波算法,提高了驱动防滑的功能安全性和鲁棒性,提升了整车驾驶性能开发效率。
