Abstract

PURPOSE: To detect failure caused by a mechanical factor by detecting a differential pressure between each brake flow control valve and each wheel cylinder of right and left front wheels, outputting a pressurization command and detecting that the differential pressure more than a designated value continues during the period of a designated time.
CONSTITUTION: The brake hydraulic pressure generated in a master cylinder 2 by operation of a brake pedal 1 is passed through flow control valves 3 through two systems of pipelines PB, PB' and supplied to the respective wheel cylinders FL, FR, RL, RR of front and rear wheels to form a designated antilock brake control device. Differential pressure between each flow control valve 3 and each wheel cylinder FL, RR of right and left front wheels by a differential pressure switch 7. A brake pressurization command is output, and it is detected that differential pressure more than a designated value continues during the period of a designated time to generate a warning of abnormality. Thus, it is possible to detect a mechanical failure such as stick of an electromagnetic solenoid of the flow control valve.
