Abstract

A tire information transmitter measures tire inflation pressure in a tire cavity region and wirelessly transmits it outside the tire cavity region. A control unit of the transmitter controls the transmitting of the measured pressure and compares the level of the pressure signal with a threshold value continually after a supply of driving power is started. The transmitter has a comparing mode in which the operation signal is transmitted at a first time interval, and a transmitting mode in which the pressure signal is transmitted at a second time interval, which is shorter than the first time interval. Further, the control unit irreversibly shifts from the comparing mode to the transmitting mode, once the level of the pressure signal exceeds the threshold value as a result of the comparing.
