Abstract
The invention relates to a method for carrying out the allocation of tire pressure control devices ( to ) to wheel positions in a tire pressure control system of a motor vehicle. Each tire pressure control device ( to ) transmits, at certain time intervals, its individual identifier and a lengthened high frequency signal to the central unit ( ) of the tire pressure control system. The high frequency signals have an individual trace which is dependent upon the rotational angle of the wheel and on the time because of the geometry of the wheel box and as a consequence of the rotation of the wheel. In the central unit ( ), a time point is fixed from two sequential high frequency signals at which the wheel assumes the same angular position in each case with this wheel being the wheel from which the signals were transmitted. The corresponding wheel has made an integer number of revolutions between the two time points. In the central unit ( ), with the aid of the signals of the rpm sensors ( to ), the wheel position is determined in which the wheel has made an integer number of revolutions between the two time points. The corresponding wheel position is allocated to the individual identifier transmitted from the tire pressure control device ( to ).
