Abstract
Official abstract text for this publication.
A vehicle is mounted with a pulse detecting unit that detects rotation of a wheel as pulses, a wheel rotation number storage unit that stores the number of pulses in correspondence with time, and a wheel position specifying device that specifies on which of the plurality of wheels the tire state detecting device arranged on each wheel is arranged. The wheel position specifying device includes a reception unit that receives a transmission signal, including a time required for the wheel to make a predetermined number of rotations, transmitted from each tire state detecting device, and a specifying unit that specifies the wheel on which each tire state detecting device is arranged from a difference of the number of pulses counted during the time included in the transmission signal and the number of pulses while the wheel makes the predetermined number of rotations.
First claim
Opening claim text (preview).
What is claimed is: 1. A wheel position specifying device arranged on a vehicle mounted with a pulse detecting unit that detects rotation of a wheel as pulses, and a wheel rotation number storage unit that stores a number of pulses detected by the pulse detecting unit in correspondence with time, a tire state detecting device being arranged on each of a plurality of wheels of the vehicle, and the wheel position specifying device specifying on which of the wheels the tire state detecting device is arranged, the wheel position specifying device comprising: a reception unit that receives a transmission signal, transmitted from each tire state detecting device; and a specifying unit that specifies on which wheel each tire state detecting device is arranged, wherein the transmission signal received by the reception unit and transmitted from each tire state detecting device includes a time required for the wheel to make a predetermined number of rotations, wherein each time the reception unit receives the transmission signal, the specifying unit tracks back by the time for the predetermined number of rotation of the wheel from the instant of receiving the transmission signal and acquires the numbers of pulses counted by each tire state detecting device until receiving the transmission signal, wherein the specifying unit specifies on which wheel each tire state detecting device is arranged from a difference of the acquired number of pulses and the number of pulses for the predetermined number of rotation of the wheel that is stored in a reception side storage unit, and wherein the predetermined number of rotations is two or more. 2. The wheel position specifying device according to claim 1 , wherein the specifying unit accumulates a difference of the number of pulses counted during the time included in the transmission signal and the number of pulses detected by the pulse detecting unit while the wheel makes the predetermined number of rotations, and specifies on which wheel each tire state detecting device is arranged from the accumulated value.
