PCT No. PCT/EP89/01377 Sec. 371 Date Jun. 14, 1991 Sec. 102(e) Date Jun. 14, 1991 PCT Filed Nov. 16, 1989 PCT Pub. No. WO90/06869 PCT Pub. Date Jun. 28, 1990.An anti-lock brake system is described in which, when an instability limit IS is exceeded by an instability criterion K K=aB+bxL+cIL+dVF (where a, b, c and d are constants and B is the relative wheel deceleration, L is the wheel slip and IL is the integral of the wheel slip and VF is the calculated vehicle deceleration, a pressure reduction pulse is produced, the width of which depends on the reduction time in the preceding cycle. This pulse also resets the integrator and the differentiator required for obtaining the wheel deceleration to 0. Between the pressure reduction pulses, pressure is held constant.
