차륜 위치 검출 장치에 있어서, 송신기(2)의 제1 제어부(23)는 상기 송신기(2)의 각도가 소정 각도로 되는 타이밍에서 반복하여 고유의 식별 정보를 포함한 프레임을 송신한다. 수신기(3)의 제2 제어부(33)는 상기 송신기(2)로부터 송신된 상기 프레임을 수신하고, 상기 프레임을 송신한 상기 송신기(2)가 복수의 차륜(5a∼5d) 중 어느 것에 설치된 것인지를 특정한다. 상기 수신기(3)는 상기 프레임을 수신할 때마다 편차 허용 폭을 노면 요철의 크기에 의해 나타내어지는 노면 상태에 따라 변경하고, 거친 노면 쪽이 거칠지 않은 노면보다도 편차 허용 폭을 넓게 설정한다.

    In a wheel position detection apparatus, a first controlling section of a transmitter repeatedly transmits a frame including specific identification information at a timing when an angle of the transmitter is at a predetermined angle. A second control unit of a receiver receives the frame transmitted from the transmitter, and identifies which of a plurality of wheels the transmitter that has transmitted the frame is attached to. The receiver changes an allowable range of variability in accordance with a road surface condition indicated by a degree of road surface roughness every time the frame is received, and sets the allowable range of variability wider for a road surface that is rough than for a road surface that is not rough.
