A tire communication apparatus of an embodiment includes a pressure sensor, a first wireless control unit and a second wireless control unit. The pressure sensor detects an air pressure of a tire. When receiving a wireless carrier sent out from a monitoring terminal by a first communication method, the first wireless control unit generates a trigger signal. The second wireless control unit is activated by the trigger signal being inputted when the second wireless control unit is stopped, acquires a detection result of the air pressure of the tire from the pressure sensor and transmits the detection result to the monitoring terminal by a second communication method different from the first communication method.
Claim CLM-00001. 1. A tire communication apparatus comprising:
a pressure sensor configured to detect an air pressure of a tire; a first wireless control unit configured to, when receiving a wireless carrier sent out from a monitoring terminal by a first communication method, generate a trigger signal; and a second wireless control unit activated by the trigger signal being inputted when the second wireless control unit is stopped, and configured to acquire a detection result of the air pressure of the tire from the pressure sensor and transmit the detection result to the monitoring terminal by a second communication method different from the first communication method.
