Abstract
A method applicable for use in wheeled vehicles permits correction of a vehicle reference speed following a real or apparent deceleration indicated by wheel speed signals, caused for example by a fault in wheel sensing. In order to prevent a brief period of insufficient braking of the vehicle due to an erroneously high vehicle reference speed during a subsequent ABS regulation, wheel slip regulating signals are monitored. If a wheel slip regulating signal appears for a given number of wheels and lasts for a longer period than a predetermined time, an intervention in the normal regulating process is made, and the vehicle reference speed is set to the value of the wheel speed of the wheels associated with a wheel slip regulating signal.
