From the output signal of the wheel generator (1), a reference signal (Vfikt) is formed in the section (2), which approximately corresponds to the effective vehicle speed (Vzug). The output signal is smoothed in the device (3) (Vrad). The difference (Vfikt - Vrad) is compared with two threshold values ( DELTA V1 and DELTA V2). When the first threshold value ( DELTA V1) is exceeded, a binary signal ( DELTA V) is formed which is integrated up linearly in time. When the difference drops below the second threshold value ( DELTA V2), the binary signal ( DELTA V) is cleared and the integral value is integrated down linearly in time. The integral value forms an auxiliary signal (HS) for the period that it exceeds a third threshold value ( DELTA V-Schwelle). When the binary signal ( DELTA V) occurs, the brakes (8) are disengaged and are only operated again when both this signal ( DELTA V) and also the auxiliary signal (HS) are cleared. <IMAGE> |
