Abstract
An anti-lock device for vehicle brakes has a wheel generator which emits pulse-type signals whose frequency is proportional to the rotary speed of the wheel. A counter counts the pulses emitted during each of successive time intervals and these pulses are connected to a first memory which stores the count of the immediate preceding time interval and to a second memory which stores the count of the time interval next preceding the intermediate time interval. A logic circuit then produces a wheel speed value which is based on the wheel speed counts of the immediate preceding and next preceding time intervals.
