ABSTRACT:
For determining a reference speed which is approximated to the actual vehicle speed, at least two wheel sensors are provided for each wheel speed to be measured. All existing wheel sensors are analyzed, and only one is selected and used for determining the reference speed as a function of the actual driving condition and of at least one defined speed criterion. At least one sensor is always available for controlling each wheel, even if one sensor is faulty.
