Abstract
A tire pressure monitoring system includes a plurality of tire pressure monitoring sensors including low frequency wireless receivers and high frequency wireless transmitters. The system further includes a plurality of low frequency transmitters each being disposed proximate one of the plurality of tire pressure monitoring sensors. The system further includes a control module in communication with the plurality of tire pressure monitoring sensors through the plurality of low frequency transmitters. In a first phase of operation the control module causes the low frequency transmitters to transmit low frequency wireless signals to the tire pressure monitoring sensors causing the tire pressure monitoring sensors to transmit data to the control module at a rate. In a second phase or operation the tire pressure monitoring sensors transmit data to the control module at a second rate.
