차륜 위치 특정 장치는, 복수의 차륜 각각에 설치되는 송신기; 및 차량의 차체에 설치되는 수신기;를 구비한다. 각 송신기는, 수신기를 향하여 신호를 송신하도록 구성되는 송신부, 대응하는 차륜과 함께 회전하여, 자신에 작용하는 가속도를 검출하는 가속도 센서, 및 가속도 센서에 의해 검출되는 가속도에 기초하여 일정위치에서 송신되는 일정위치신호 및 일정출력으로 송신되는 위치검출신호를 송신부로부터 송신하도록 구성되는 송신측 제어부를 갖는다. 수신기는, 신호를 수신하도록 구성되는 수신부, 일정위치신호를 수신한 시점에서의 각 차륜의 회전위치의 편차로부터 대응하는 송신부가 설치된 차륜의 위치를 특정하는 제1특정처리와, 상기 위치검출신호의 수신강도로부터 대응하는 송신기가 설치된 차륜의 위치를 특정하는 제2특정처리를 행하도록 구성되는 수신측 제어부를 갖는다.

    A wheel assembly position identifying apparatus includes transmitters, each of which is provided in one of wheel assemblies, and a receiver, which is provided in a body of a vehicle. Each transmitter includes a transmission section, which is configured to transmit signals to the receiver, an acceleration sensor, which is configured to rotate together with the corresponding wheel assembly and detect acceleration acting on the acceleration sensor, and a transmission-side control section, which is configured to cause the transmission section to transmit a constant position signal and a position detecting signal. The constant position signal is transmitted at a constant position based on the acceleration detected by the acceleration sensor. The position detecting signal is transmitted at a constant power. The receiver includes a reception section, which is configured to receive the signals, and a reception-side control section, which is configured to execute a first identifying process and a second identifying process. In the first identifying process, the positions of the wheel assemblies, in which the corresponding transmitters are provided, are identified based on variations of the rotational positions of the wheel assemblies at the time when the constant position signals are received. In the second identifying process, the positions of the wheel assemblies, in which the corresponding transmitters are provided, are identified based on the received signal strength indications (RSSIs).
