An antilock braking system is described in which, after a pressure reduction, the pressure is again built up for a time duration having first a large gradient and then a smaller gradient. The invention relates to the optimal determination of that duration. It is proposed to make that duration a function of the duration of the directly preceding pressure reduction and of the ratio of the duration of the pressure buildup to the duration of the pressure reduction in the preceding control cycle.

An antilock braking system for a vehicle comprising: (a) at least one sensor for monitoring the speed of a vehicle wheel and producing wheel speed signals; (b) an electronic evaluation circuit which evaluates the wheel speed signals and generates control signals for a brake pressure control system which reduces and increases brake pressure in control cycles, said brake pressure being increased for a time duration at first with a large gradient relative to the gradient over the entire time duration and then with a relatively smaller gradient until a desired increase in pressure is reached; and (c) a timing device which determines said time duration of brake pressure increase, said time duration being a function of the pressure reduction time in the current control cycle and of the ratio of the pressure buildup time to the pressure reduction time in the immediately preceding control cycle.
