Brake control system

摘要

There is provided a brake control system for carrying out ABS control in which the brake hydraulic pressure is reduced by a brake unit in accordance with a difference between a pseudo vehicle body speed and each of wheel speeds so as to prevent wheel locking. A control unit is configured to detect an abnormality in output of wheel speed sensors, and to determine the pseudo vehicle body speed in accordance with outputs from the wheel sensors except the wheel determined as being abnormal. The control unit determines whether the abnormal wheel is a drive wheel or a non-drive wheel, and to reset the determination of abnormality under conditions differentiated in accordance with whether the abnormal wheel is a drive wheel or a non-drive wheel. <IMAGE>
