ABSTRACT:
To prevent oscillation of a wheel being intermittently braked in an anti-slip or anti wheel block system, an increase of braking pressure, after a prior decrease, is controlled to occur during a first time interval which is short with respect to an oscillation period of the wheel if subjected to brake pressure pulses, so that the braking pressure increase will be small or short, e.g. about 3 milliseconds, comparable to stepped pressure increases after an initial wheel deceleration and permitted re-acceleration, the pressure then being maintained at an even level for an interval (T.sub.3) which, likewise, is short with respect to the intervals (T.sub.0, T.sub.4) between stepped increases. The respective time intervals can be controlled by individual, special pulse generators, or by suitable programming of microprocessor elements.
