Patent ID: 6888446

Claim:
An automotive tire pressure monitoring assembly ( 10 ) for use in an automobile ( 12 ) including at least one noise generating assembly ( 12 ) actively radiating a spectral noise signal comprising: at least one tire pressure sensor ( 34 ) generating a pressure signal ( 50 ) based on the pressure of air within a tire ( 14 ), said tire pressure sensor ( 34 ) including a sensor receiver ( 68 ) in communication with a sensor control logic ( 38 ), said sensor control logic ( 38 ) adapted to receive the spectral noise signal ( 20 ) from the at least one noise generating assembly ( 18 ); a controller assembly ( 52 ) positioned within the automobile ( 12 ) and in remote communication with said at least one tire pressure sensor ( 34 ); and a positioning logic adapted to determine the position of said at least one tire pressure sensor ( 34 ) based on the strength of the spectral noise signal ( 20 ).
