Abstract
A method for determining an accurate vehicle speed, based upon the wheel speed data, for vehicle antilock systems in which the integrity of each individual wheel speed value is verified before including that wheel speed value in the reference speed calculation. Reference speed is then computed as a function of only those wheel speed values which have been successfully accepted into the calculation.
