The invention relates to an ABS control strategy for a bumpy road surface. The ABS control strategy comprises the following steps: setting the initial slip rate S triggered by an ABS controller; in the vehicle driving state, judging the driving road surface state, if the driving road surface is a conventional road surface, not adjusting the slip rate triggered by the ABS controller, and keeping the initial slip rate S; if the driving road surface is a bumpy road surface, adjusting the slip rate triggered by the ABS controller to be S1, wherein S1 is greater than S. According to the technical scheme, the ABS cannot be triggered when the automobile slightly brakes and passes through a bumpy road surface, and a customer cannot hear the pressurization noise of the ABS and has the feeling of pushing feet by pedals; the insufficient deceleration caused by reduction of the pressure of the wheel cylinder when the ABS is triggered is reduced, and the ABS can be protected from being triggered when a customer slightly steps on a brake on a bumpy road.

    本发明涉及一种颠簸路面的ABS控制策略,包括以下步骤:设定ABS控制器触发的初始滑移率S;在车辆行驶状态下,判断行驶的路面状态,若行驶的路面为常规路路,则不对ABS控制器触发的滑移率进行调节,保持初始滑移率S,若行驶的路面为颠簸路面,则将ABS控制器触发的滑移率调整为S1,S1大于S。通过本技术方案轻微制动下过颠簸路面,ABS不会触发,客户不会听到ABS加压噪音和有踏板顶脚感;减少ABS触发时,由轮缸压力减小引起的减速度不足,并能保护客户在过颠簸路面时,轻踩刹车时,ABS不会触发。
