Patent ID: 7113084

Claim:
A method for locating tire condition sensing apparatuses, wherein said method is used for recognizing a plurality of tire condition sensing apparatuses mounted on a vehicle, said method comprising: providing a plurality of antennas, wherein said antennas are corresponding to said tire condition sensing apparatuses; turning on said antennas for receiving and decoding a signal emitted from one of said tire condition sensing apparatuses; generating a first signal intensity, wherein said signal includes an identification code belonging to said one of said tire condition sensing apparatuses emitting said signal; alternately turning on/off each of said antennas so as to obtain a plurality of second signal intensities; respectively comparing each of said second signal intensities with said first signal intensity so as to obtain a plurality of signal intensity changes; comparing said signal intensity changes so as to obtain a maximum value; and determining the location of said one of said tire condition sensing apparatuses which is emitting said signal, wherein said maximum value is generated while one of said antennas is being turned on/off, so that said one of said tire condition sensing apparatuses is corresponding to said one of said antennas.
