The invention belongs to the technical field of anti-lock braking system control, and particularly relates to an anti-lock braking system control method and an anti-lock braking system control system. Obtaining a final expected slip rate according to the road condition and the vehicle speed; determining a slip rate grade according to a function triggered by the vehicle; according to the slip rate grade, the final expected slip rate control range is narrowed; according to the method, acceleration and deceleration threshold values of wheels and slip rate control are more effectively combined, and the control range of the slip rate of the ABS is judged by combining road surface types (dry, wet, icing, snowing and the like) provided by a road surface recognition system and judgment logic of an active avoidance system, so that the self-adaptive control capability of the system is improved.
本发明属于防抱死系统控制技术领域,具体涉及一种防抱死系统控制方法及防抱死系统控制系统,通过识别路面情况;根据路面情况及车速获取最终预期滑移率;根据车辆触发的功能确定滑移率等级;以及根据滑移率等级,缩小最终预期滑移率控制范围;实现了将车轮的加、减速度门限值和滑移率控制更有效地结合起来,结合路面识别系统提供的路面类型(干、湿、结冰、下雪等)以及主动避让系统的判断逻辑,判断ABS系统滑移率的控制范围,从而提高系统的自适应控制能力。
