Abstract:
1. A method of measuring and analyzing tire air pressure according to a wheel position of a vehicle, comprising the steps of: coupling each of a plurality of wheels of the vehicle to an air pressure checking device, an LF receiver, an analysis unit, and an RF-transmission device; allocating an individual wheel code to each of the plurality of wheels; providing an LF signal to the LF receiver by an LF transmission device of a central unit; analyzing the amplitude of the LF signal to determine a wheel rotation rate for each of the plurality of wheels; sending an RF signal to the central unit, the RF signal being coupled with information about the wheel rotation rate and the individual wheel code; determining the wheel position for each of the plurality of wheels using a measurement device according to the wheel rotation rate; and enabling the air pressure checking device according to the individual wheel code to sense the tire air pressure associated with the wheel position.
