Abstract:
A tire condition sensor module for a vehicle comprising:a tire condition sensor operative to sense a tire condition of a vehicle tire and provide a tire condition signal indicative thereof;a motion detector operative to detect movement of the associated vehicle tire and to provide a motion signal indicating movement of the vehicle tire;a transmitter operative to transmit a tire transmitter signal having a characteristic based on the tire condition signal; anda controller connected with said motion detector, said transmitter, and said tire condition sensor, said controller controlling said tire condition sensor to sense the tire condition at a first sensing rate during an initial time period in which said motion signal indicates less than a predetermined amount tire movement and controlling said transmitter during the initial time period to transmit said tire transmitter signal depending on the sensed tire condition, said controller controlling said tire condition sensor 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.
