Process for monitoring the condition of motor vehicle wheels

A process for monitoring the state of a wheel of a motor vehicle, comprising the steps of:

• converting an output signal (MS) generated by a sensor (S) into an essentially rectangular pulse signal (l);
• measuring a respective duration of the pulses;
• determining a particular weighted average between a current duration value of a current pulse and a preceding duration value of a preceding pulse, wherein the current pulse and the preceding pulse lie a specific step size apart, wherein the specific step size is the number of consecutive pulses from the current pulse to the preceding pulse;
• and
• determining a correction factor (ki) from each deviation between the current duration value and the particular weighted average;
• wherein said step size (j) is correlated with an error order (m) of a fault and wherein the step size (j) with a periodic deviation of the mth order (m) that is to be eliminated is determined according to the formula j=1/m×n/4 for motor vehicles.
