Abstract
The method is designed for a motor vehicle equipped with wheel rpm sensors and means to determine whether the wheels are either rolling normally or locked or spinning without adhesion. The method employs plausibility routines to determine whether an abnormal wheel rpm sensor signal is due to locking or spinning of the wheel or whether it is due to a sensor failure. In case that an abnormal condition is detected, an alternate strategy is initialized to determine wheel rpm rates and perform control functions that are based on wheel rpm rates.
