METHOD FOR ASSOCIATING TYRE PRESSURE CONTROL APPARATUSES WITH THE VARIOUS POSITIONS OF A NUMBER OF WHEELS ON A VEHICLE

摘要

Tire pressure control devices include first sensors to deliver repeatedly a measured value M1 for the rotation speed of the wheel. A measurand, from which the rotation speed of the associated wheel can be derived, is detected in a pointwise manner by means of a second sensor over a predetermined rotation angle &phgr; of the wheel as a function of time, is subjected to a low pass filtering in a subsequent first time interval &Dgr;t1 and from the filtered development of the measurand a second measured value M2 is determined, which is a measurement for the rotation speed or respectively for the angular speed of the associated wheel. Each tire pressure control device transmits at the end of a second time interval &Dgr;t2 the second measured value M2 together with an identification of the tire pressure control device to a central unit. Comparing M1 and M2 determines wheel position.
