Abstract

The setpoint generator according to the invention utilizes the information "pedal travel s" in combination with the information "pedal force p" by weighting them in input circuits 4,5 and summing up the corresponding partial setpoints p'.sub.s and p'.sub.p to form a setpoint p'.sub.Hz. Here, a countercurrent weighting takes place: If a small force acts on the pedal, the pedal travel is dominant; as the pedal force is growing, the latter is weighted more heavily. In this way, a smooth brake behavior is attained, whereby the comfort is enhanced and the wear of the employed components is reduced.
