Abstract
An improved vehicle wheel anti-lockup brake control system in which a shutdown signal is generated to disable the wheel anti-lockup control system in the event of a malfunction, as determined by the concurrent presence of a wheel slip signal and a low wheel speed signal (generated by the same wheel) for a predetermined period of time sufficient to allow a normally operative anti-lockup control system to correct a slipping wheel before it locks up.
