ABSTRACT:
A method of controlling the brake pressure in an anti-lock vehicle brake system provides for short distances to stop to be reached even with greatly differing mass moments of inertia by calculating the pressure reduction period of a control cycle currently under way as the product of a first factor and a second factor. The first factor depends on the pressure reduction period in the preceding control cycle, and the second factor depends on the maximum re-acceleration of the wheel in the preceding control cycle.
