METHOD AND APPARATUS FOR SENSING TIRE PRESSURE IN A VEHICLE WHEEL

摘要

The invention provides a wireless tire pressure sensing method and apparatus (290). The method and apparatus (290) include a transducer (295), a power source, a transmitter, and a receiver (300). The transducer (295) measures a pneumatic pressure and/or temperature and/or wheel speed that is converted into a wireless data signal by the transmitter (295). The receiver (300) receives the signal from the transmitter and thereafter transfers the signal to a controller (360). The method and apparatus may use one or more antennas to transmit and/or receive data between the transmitter (295) and the receiver (300).
