Title
(EN) WHEEL POSITION DETECTING DEVICE AND TIRE PRESSURE DETECTING APPARATUS HAVING THE SAME
(FR) DISPOSITIF DE DÉTECTION DE POSITION DE ROUE ET APPAREIL DE DÉTECTION DE PRESSION DE PNEU COMPORTANT CELUI-CI
Abstract
(EN) In a wheel position detecting device, a transmission angular position of a transmitter (2) to transmit a frame from the transmitter (2) to a receiver (3) is changed by a predetermined angle each time the transmitter (2) transmits the frame. A receiver (3) acquires gear information indicating a tooth position of a gear (12a - 12d) rotating in association with a corresponding wheel (5a - 5b), based on a detection signal of a wheel speed sensor (11a - 11d). The receiver (3) specifies to which wheels (5a - 5d) the transmitter (2) is integrated, based on the tooth position of the gear at a reception timing of the frame.
(FR) Dans un dispositif de détection de position de roue, une position angulaire de transmission d'un émetteur (2) pour transmettre une trame de l'émetteur (2) à un récepteur (3) est modifiée d'une valeur d'angle prédéfinie à chaque fois que l'émetteur (2) transmet la trame. Un récepteur (3) obtient des informations d'engrenage indiquant une position de dent d'un engrenage (12a - 12d) tournant en association avec une roue correspondante (5a - 5b), sur la base d'un signal de détection d'un capteur de vitesse de roue (11a - 11d). Le récepteur (3) spécifie à quelles roues (5a - 5d) est intégré l'émetteur (2), sur la base de la position de dent de l'engrenage à un moment de réception de la trame.
