Abstract
Abstract A system ( 10 ) and associated method for tire condition communication for a vehicle ( 12 ). The system ( 10 ) includes a sensor ( 18 ), associated with a tire ( 14 ), to sense at least one tire condition. Transmitter components ( 22, 24 and 30 ), associated with the tire ( 14 ) and operatively connected to the sensor ( 18 ), provide for transmission of a signal ( 32 ) that has a data rate and that indicates the sensed tire condition. A receiver unit ( 40 ), associated with the vehicle ( 12 ), receives the signal ( 32 ). The receiver unit ( 40 ) includes a plurality of antennas ( 42 A- 42 N), each for receiving the transmitted signal ( 32 ), and a switching device ( 46 ) among the plurality of antennas at a rate that is quicker than the data rate of the transmitted signal ( 32 ).
