Abstract
A tire condition sensor module (14) includes a tire condition sensor (78, 84, 88) operative to sense a tire condition of an associated tire (20) and provide a signal indicative thereof. A motion detector (32) is operative to detect movement of the tire and provide a motion signal indicative thereof. A transmitter (44) transmits a tire transmitter signal indicative of the tire condition signal. A controller (72) is connected with the motion detector (32), the transmitter (44), and the tire condition sensor (78, 84, 88). The controller (72) controls the tire condition sensor (78, 84, 88) to sense the tire condition at a first sensing rate during an initial time period in which the motion signal indicates less than a predetermined amount tire movement. The controller (72) controls the transmitter (44) during the initial time period to transmit the tire transmitter signal depending on the sensed tire condition. The controller (72) controls the tire condition sensor (78, 84, 88) after the initial time period to sense at a second sensing rate, which is less than the first sensing rate, so long as the motion signal continues to indicate less than the predetermined amount of tire movement.
