ABSTRACT:
An antilock brake controller provides an adaptive pressure hold period that interrupts the release of brake pressure during the pressure release phase of an antilock braking pressure control cycle of a vehicle wheel by holding the brake pressure constant while the wheel slip rate is below a threshold that is adjusted as a predetermined function of wheel slip for the front wheels and as a predetermined function of wheel acceleration for the rear wheels.
