Patent ID: 7716976

Claim:
A method for determining tire location on a vehicle in a tire pressure monitoring system comprising the steps of: generating low frequency initiation signals; controlling transmission strength of said generated low frequency initiation signals; controlling transmission direction of said generated low frequency initiation signals so as to direct said generated low frequency initiation signals toward a first tire on a vehicle, the first tire and a second tire of said vehicle having associated initiation signal receivers; transmitting a response signal from the first tire upon receiving the initiation signal, the response signal having at least an unique identification signal portion associated with the first tire receiving the initiation signal; receiving the transmitted response signal from the first tire with the unique identification signal portion; associating the received unique identification signal portion of the response signal from the first tire with a location on the vehicle; readjusting signal strength of said generated low frequency initiation signal so that the second tire on said vehicle responds to each transmission of said readjusted signal strength initiation signal; and associating the received unique identification signal portion of the response signal from the second tire with a location on the vehicle.
