Abstract
Antilock control system generates an instability criterion from at least one of slip and deceleration of the wheels and produces control signals for reducing brake pressure at the wheels when the criterion exceeds an instability threshold. The system delays the criterion reaching the threshold, for example by increasing the threshold, when vehicle deceleration increases and when downhill travel is determined. The instability criterion S may be calculated according to S=aV+bL+c.intg.Ldt, where V is the wheel deceleration, L is the wheel slip, and a, b, and c are constants.
