The invention discloses an anti-lock control method for a fault scene of a wheel speed sensor, and the main design conception of the anti-lock control method is as follows: after the fault of the wheel speed sensor is detected, the braking working condition of a vehicle is monitored, and once the emergency braking working condition is monitored, the braking oil pressure corresponding to each wheel is collected; according to the fault number of the wheel speed sensors, if only a single wheel speed sensor breaks down, the brake oil pressure of a wheel coaxial with the fault wheel is compared, and the anti-lock control strategy of the fault wheel is determined; and if a plurality of wheel speed sensors fail, correspondingly adopting an anti-lock control strategy of wheels which are coaxial and/or on the same side with the fault wheels according to the number of different fault wheels. According to the invention, the potential safety hazard when emergency braking occurs on the premise that one or more wheel speed sensors break down and cannot be maintained in time is effectively eliminated, so that the safety and driving experience of the vehicle are remarkably improved.

    本发明公开了一种用于轮速传感器故障场景的防抱死控制方法,本发明的主要设计构思在于,在检测到轮速传感器故障后,监测车辆的制动工况,一旦监测到紧急制动工况,则采集各车轮对应的制动油压;接着根据轮速传感器故障数量,如仅为单个轮速传感器故障,则通过比对与故障轮同轴的车轮的制动油压,确定故障轮的防抱死控制策略;如为多个轮速传感器故障,则根据不同的故障轮的数量,对应采用与故障轮同轴和/或同侧的车轮的防抱死控制策略。本发明有效消除了在单个或多个轮速传感器出现故障且无法及时维修的前提下,当发生紧急制动时的安全隐患,由此显著提高了车辆的安全性及驾驶体验感。
