Zusammenfassung:	A method for checking and controlling the quality of output signals (20) from wheel speed sensors (18) installed on wheels (14) of vehicles (10) equipped with an automatic braking system (12) is disclosed as determining from sensed wheel speeds the deceleration of a wheel (14), timing any period of deceleration the level of which is above a predetermined level, defining any wheel speed sensor (18) associated with a wheel (14) having an indicated deceleration above the predetermined level for a time exceeding a predetermined period as being malfunctioning, excluding the output signals (20) from the malfunctioning wheel speed sensor (18), and replacing the excluded output signals (20) with output signals (20) from a wheel speed sensor (18) installed on an alternate wheel (14).
