Abstract
A process and device for monitoring the state of a wheel of a motor vehicle in which an output signal of a sensor is converted into an essentially rectangular pulse signal. A respective duration of the pulse is measured; and an especially weighted average between the duration of a current value and a preceding value is determined, wherein a current value and a preceding value exhibit a time interval and/or lie a specific step size apart. A correction factor is determined from each deviation between the duration of a current value and a respective mean value. A step size of the correction method is matched to an error order of a fault. Preferably the step size with a periodic deviation of the morder that is to be eliminated is determined according to the formula j=1/m×n/4; for motor vehicles in particular according to the formula j=1/m×12.
