Abstract
A wheel anti-blocking control system (ABS), in which, subsequent to a brake pressure drop, the first brake pressure rise pulse .DELTA.P.sub.2 is controlled, in dependence on the preceding brake pressure drop (.DELTA.P.sub.1) and on a quotient defined by the relationship: ##EQU1## in which +.omega..sub.m and -.omega..sub.m are representative of maximum angular acceleration/deceleration of the respective wheel being controlled and .alpha. is a factor somewhat less than unity, and which may vary in dependence on the direction of movement of the vehicle, for example whether the vehicle is moving in a straight path or is moving along a curve. If moving along a curve, so that angular acceleration is involved, the factor .alpha. is reduced.
