Title:
WHEEL-POSITION SPECIFYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/208055
Kind Code:
A1
Abstract:
A wheel-position specifying device that is provided with transmitters that are respectively provided to a plurality of wheels and with a receiver that is provided to a vehicle body. Each transmitter has: a transmission unit that is configured so as to transmit signals toward the receiver; an acceleration sensor that rotates with the wheel that corresponds thereto and that detects the acceleration that acts thereon; and a transmission-side control unit that causes a fixed-position signal, which is transmitted at a fixed position on the basis of the acceleration detected by the acceleration sensor, and a position-detection signal, which is transmitted at a fixed output, to be transmitted from the transmission unit. The receiver has: a reception unit that is configured so as to receive signals; and a reception-side control unit that is configured so as to perform first specifying processing, which specifies, from the variation in the rotational positions of the wheels at the point in time at which a fixed-position signal is received, the position of the wheel to which the corresponding transmission unit is provided, and second specifying processing, which specifies, from the reception strength of a position-detection signal, the position of the wheel to which the corresponding transmitter is provided.
