Beschreibung
Zusammenfassung:	A wheel lock control circuit includes a deceleration switch which effects release of the vehicle brake pressure when the deceleration of the vehicle wheels are greater than a reference deceleration. A portion of the reference deceleration is provided by an adaptive control circuit which is responsive to wheel deceleration to supply a signal representing an estimate of vehicle deceleration. An initial cycle circuit provides an initial high level portion of the reference deceleration to desensitize the system to noise signals and wheel transients. The initial cycle output of the initial cycle circuit is controlled by a portion of the adaptive control circuit which is responsive to wheel deceleration and which has a time constant greater than the deceleration switch so that the initial cycle circuit is effective to desensitize the wheel lock control circuit to system noise and vehicle transients independent of the deceleration switch response to the acceleration and reference signals.
