Abstract
A tire pressure monitoring unit is mounted on a vehicle wheel having a pressure and acceleration sensor. A method for assigning wheel positions includes pressure and acceleration data determined from the sensors. The pressure data and at least one piece of information derived from the acceleration data are transmitted wirelessly in a data telegram together with a characteristic identifier. Information concerning the reliability of the information derived from the acceleration data is acquired in the tire pressure monitoring unit on the basis of the measurements and is transmitted with the data telegram. A central evaluation unit considers a plurality of data telegrams and, taking account of data from the ABS sensors, assigns the individual tire pressure monitoring units to wheel positions. Data telegrams in which the reliability is higher receive a greater weighting, and data telegrams in which the reliability is smaller receive a smaller weighting.
