차륜 회전위치 특정장치는, 가속도 검출부; 제어부; 및 해당 장치의 전력원이 되는 전지;를 구비한다. 가속도 검출부는 차륜의 회전위치에 따라 변화하는 가속도를 검출한다. 제어부는 가속도 검출부에 의해 검출된 가속도에 기초하여 차륜의 회전위치를 특정한다. 제어부는, 차륜의 회전위치가 특정 가능한 통상 모드와, 차륜의 회전위치의 특정에 있어서의 소비전력이 상기 통상 모드보다 작은 절전 모드로부터 선택된 제어 모드로 작동한다. 제어부는, 외부로부터의 입력에 따라 개시조건이 성립한 경우에 제어 모드를 통상 모드로 전환하고, 통상 모드에서 종료조건이 성립한 경우에 제어 모드를 절전 모드로 전환한다.

    A wheel assembly rotational position identifying apparatus includes an acceleration detector (44), a control section (41), and a battery (48), which is a power source for the apparatus. The acceleration detector (44) detects an acceleration that changes in accordance with the rotational position of the wheel assembly (13). The control section (41) identifies the rotational position of the wheel assembly (13) based on the acceleration detected by the acceleration detector (44). The control section (41) operates in a control mode that is a selected one of a normal mode, in which the rotational position of the wheel assembly (13) is allowed to be identified, and a power saving mode, in which a power consumption associated with identification of the rotational position of the wheel assembly (13) is smaller than that in the normal mode. The control section (41) switches the control mode to the normal mode when an initiation condition is met in accordance with an input from outside. The control section (41) also switches the control mode to the power saving mode when a termination condition is met in the normal mode.
