Abstract
A tire management system includes a sensor module secured to inside of a tire that is mounted on a vehicle, for measuring a tire state value and transmitting the measured data to the vehicle side, and a receiver module secured to the vehicle side for transmitting a signal demanding the measured data to the sensor module at a predetermined cycle and receiving the measured data transmitted from the sensor module. The sensor module measures a tire status value at a predetermined cycle, judges whether the measured data is out of a predetermined normal range, and immediately transmits the measured data and an abnormal state data through a predetermined channel exclusively used for transmitting the abnormal state data to the receiver module, if the data is judged to be out of the normal range. With this structure, if an abnormal state occurs, the receiver module can receive the abnormality without any delay, while preventing shortening of the cell life.
