Abstract
An anti-lock braking control system is described in which the braking pressure cycle is filtered by limiting the minimum time period of each brake pressure cycle. The period from the time a brake pressure release phase is initiated until the next brake pressure release phase is called for is timed. If the time is less than a predetermined value, the brake pressure is held constant until the minimum time period has expired.
