Patent attributes
A tire condition detecting apparatus includes a condition detecting section, a transmission section, and a transmission-side control section. The transmission section is configured to transmit a signal that contains information related to the condition of the tire to a receiver, which includes a reception-side control section. The reception-side control section identifies the position of the wheel assembly in which the tire condition detecting apparatus is provided based on the received signal strength indication (RSSI) of the signal. The transmission-side control section is configured to cause a position detecting signal and an instruction signal to be transmitted from the transmission section to the receiver. The position detecting signal is configured to cause the reception-side control section to identify the position of the tire condition detecting apparatus. The instruction signal is transmitted before the position detecting signal is transmitted and instructs the reception-side control section to start obtaining the RSSI.
