Abstract:
(EN) Provided is an on-vehicle communication system, an on-vehicle device and a portable apparatus. This on-vehicle device is provided with: an on-vehicle side transmitting part which alternately two kinds of detection signals having phases different by 180 degrees; an on-vehicle side receiving part which receives a response signal transmitted from a portable apparatus with respect to the detection signal transmitted by the on-vehicle side transmitting part; and a position detection part which detects the position of the portable apparatus on the basis of the response signal received from the on-vehicle side receiving part. The portable apparatus is provided with: a portable apparatus-side receiving part which receives the two kinds of detecting signals transmitted from the on-vehicle transmitting part; a subtraction part which subtracts one from the other of the two kinds of received detecting signals; a calculation part which, on the basis of the signal obtained through the subtraction by the subtraction part, calculates signal intensities of the detecting signals received by the portable apparatus-side receiving part; and a portable apparatus-side transmitting part which transmits a response signal including information about the signal intensities calculated by the calculation part.
(FR) L'invention concerne un système de communication embarqué, un dispositif embarqué et un appareil portable. Ce dispositif embarqué comprend: une partie de transmission côté embarqué qui, en alternance, envoie deux types de signaux de détection présentant des phases différentes de 180 degrés; une partie de réception côté embarqué qui reçoit un signal de réponse émis par un appareil portable par rapport au signal de détection émis par la partie de transmission côté embarqué; et une partie de détection de position qui détecte la position de l'appareil portable sur la base du signal de réponse reçu de la partie de réception côté embarqué. L'appareil portable comprend : une partie de réception côté appareil portable qui reçoit les deux types de signaux de détection transmis par la partie de transmission embarquée; une partie de soustraction qui soustrait l'un de l'autre des deux types de signaux de détection reçus; une partie de calcul qui, sur la base du signal obtenu par la soustraction effectuée par la partie de soustraction, calcule des intensités de signaux de détection reçus par la partie de réception côté appareil portable; et une partie de transmission côté appareil portable qui transmet un signal de réponse comprenant des informations concernant les intensités de signal calculées par la partie de calcul.
(JA) 車載通信システム、車載装置及び携帯機の提供。 車載装置は、互いに位相が180度異なる2種類の検出信号を交互に送信する車載側送信部と、車載側送信部が送信した検出信号に対して携帯機から送信される応答信号を受信する車載側受信部と、車載側受信部にて受信した応答信号に基づき、携帯機の位置を検出する位置検出部とを備え、携帯機は、車載側送信部から送信される2種類の検出信号を受信する携帯機側受信部と、受信した2種類の検出信号の一方から他方を減算する減算部と、減算部により減算して得られる信号に基づき、携帯機側受信部が受信した検出信号の信号強度を算出する算出部と、算出部により算出した信号強度の情報を含む応答信号を送信する携帯機側送信部とを備える。
