(FR) DISPOSITIF DE COMMUNICATION SANS FIL EMBARQUÉ ET PROCÉDÉ DE DÉTECTION D'INFORMATIONS DE DISTANCE
(JA) 車載無線通信装置及び距離情報検出方法
Abstract:
(EN) An in-vehicle wireless communication device that is mounted in a vehicle (1) and is for wireless communication with a mobile terminal (10) carried by a user of the vehicle, said in-vehicle wireless communication device comprising: a calibration information storage unit (105) for storing, in a state in which the mobile terminal has been identified, calibration information to be used in combination with the radio field strength of the mobile terminal; a wireless communication unit (101) for wirelessly communicating with the mobile terminal in a state in which the mobile terminal has been identified; a radio field strength detection unit (102) for detecting the radio field strength of the radio waves received from the mobile terminal in the wireless communication; and a distance information detection unit (104) for detecting information about the distance to the mobile terminal on the basis of the radio field strength of the radio waves received from the mobile terminal and the calibration information stored for the mobile terminal.
(FR) L'invention concerne un dispositif de communication sans fil embarqué monté dans un véhicule (1) et destiné à une communication sans fil avec un terminal mobile (10) porté par un utilisateur du véhicule, ledit dispositif de communication sans fil embarqué comprenant : une unité de mémorisation d'informations d'étalonnage (105) permettant de mémoriser, dans un état dans lequel le terminal mobile a été identifié, des informations d'étalonnage à utiliser en combinaison avec l'intensité de champ radioélectrique du terminal mobile ; une unité de communication sans fil (101) permettant de communiquer sans fil avec le terminal mobile dans un état dans lequel le terminal mobile a été identifié ; une unité de détection d'intensité de champ radioélectrique (102) permettant de détecter l'intensité de champ radioélectrique des ondes radioélectriques reçues en provenance du terminal mobile dans la communication sans fil ; et une unité de détection d'informations de distance (104) permettant de détecter des informations concernant la distance au terminal mobile en fonction de l'intensité de champ radioélectrique des ondes radioélectrique reçues en provenance du terminal mobile et des informations d'étalonnage mémorisées pour le terminal mobile.
(JA) 車両(1)に搭載されて、該車両の使用者によって携帯される携帯端末(10)と無線通信する車載無線通信装置であって、携帯端末の電波強度と組み合わせて用いられる較正情報を、携帯端末を識別した状態で記憶している較正情報記憶部(105)と、携帯端末を識別した状態で携帯端末と無線通信する無線通信部(101)と、無線通信中に携帯端末から受信した電波の電波強度を検出する電波強度検出部(102)と、携帯端末から受信した電波の電波強度と、携帯端末に対して記憶されている較正情報とに基づいて、携帯端末までの距離情報を検出する距離情報検出部(104)と、を備える。
