Tire condition detecting apparatus and tire condition monitoring apparatus
First Claim
1. A tire condition detecting apparatus that is provided in each of wheel assemblies of a vehicle to detect a condition of a tire, the apparatus comprising:
- a condition detecting section, which detects the condition of the tire;
a transmission section, which 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, wherein the reception-side control section identifies the position of the wheel assembly in which the tire condition detecting apparatus is provided based on a received signal strength indication (RSSI) of the signal; and
a transmission-side control section, which causes the transmission section to transmit the signal,wherein 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, wherein the position detecting signal is configured to cause the reception-side control section to identify the position of the tire condition detecting apparatus, and the instruction signal is transmitted before the position detecting signal is transmitted and instructs the reception-side control section to start obtaining the RSSI.

Abstract
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.

5. A tire condition monitoring apparatus comprising:
-
a tire condition detecting apparatus; and a receiver, which receives a signal transmitted from the tire condition detecting apparatus to obtain a condition of a tire, wherein the tire condition detecting apparatus is provided in each of wheel assemblies of a vehicle to detect the condition of the tire, the tire condition detecting apparatus includes a condition detecting section, which detects the condition of the tire; a transmission section, which 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, wherein the reception-side control section identifies the position of the wheel assembly in which the tire condition detecting apparatus is provided based on a received signal strength indication (RSSI) of the signal, and a transmission-side control section, which causes the transmission section to transmit 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, wherein the position detecting signal is configured to cause the reception-side control section to identify the position of the tire condition detecting apparatus, and the instruction signal is transmitted before the position detecting signal is transmitted and instructs the reception-side control section to start obtaining the RSSI, the receiver includes a receiving section, which receives the signal transmitted from the tire condition detecting apparatus, and a measuring section, which measures a received signal strength indication (RSSI) of the received signal, the reception-side control section obtains the RSSI measured by the measuring section and identifies, based on the obtained RSSI, the position of the wheel assembly in which the tire condition detecting apparatus that has transmitted the signal is provided, and the reception-side control section is configured to obtain the RSSI when receiving an instruction signal that instructs to obtain the RSSI.
