Abstract

A method for avoiding false excitations of a slip control system comprises monitoring of a wheel speed signal for a predefined first monitoring time period for the start of a negative half-wave of an oscillation applied to a vehicle wheel, when a brake pressure gradient initiated by a brake start rises above a predetermined threshold. A ruck signal is derived from the wheel speed signal. An acceration signal is derived from the wheel speed signal during a predetermined second monitoring period. The wheel speed signal is monitored for a turning point of the ruck signal and a start of the acceleration signal. The oscillation imposed on the vehicle wheel is identified as a braking-induced vibration, and slip control is not carried out when the turning point of the ruck signal and the re-acceleration of the wheel are detected.
