Abstract

Described is a drive slip-control system in which reference wheelrotation rates wref(i) are specified and, in a control unit comprising three parallel-connected variable-gain amplifiers, braking-moment values are determined for both sides from the difference in the rates of rotation (w1+wr) and the reference rates of rotation, as well as the engine rpm. These braking moment values, which represent summed reference braking moments, are converted into brake-valve control times.
