A control unit of a vehicle brake system has a receive circuit for tapping and processing a digital signal provided by an active speed sensor for speed measurement on a vehicle wheel. The signal includes information concerning the speed of a pole wheel, which is arranged in front of the sensor, spaced therefrom by an air gap, and which rotates along with the wheel. The signal also includes an actual air gap value digitized in stages and comprising several bits. The control unit also has a comparator circuit for comparing the actual air gap value to a reference air gap value and for determining whether the actual air gap value exceeds the reference value by more than a defined tolerance value. An information circuit of the control circuit generates early warning information when the comparator circuit determines that the actual air gap value exceeds the reference value by more than the tolerance value.
