Abstract

In an anti-lock braking system in which pressure is reduced in pulses separated by pressure maintenance phases, the duration of the first maintenance phase is dependent upon the vehicle deceleration and the wheel slip. A second pressure reduction pulse is triggered only when the wheel acceleration is less than a predetermined low threshold.
