Title (EN) VEHICLE SYSTEM, PORTABLE MACHINE, AND VEHICLE-MOUNTED DEVICE
(FR) SYSTÈME DE VÉHICULE, MACHINE PORTABLE ET DISPOSITIF EMBARQUÉ
(JA) 車両システム、携帯機、及び車載装置
Abstract:
(EN) A vehicle system (1, 101, 201, 301) is provided with a portable machine (50), a vehicle-mounted device (10), a position acquiring unit (21, 61), an attitude acquiring unit (65) and a determining unit (22, 62). The vehicle-mounted device communicates with the portable machine by transmitting linearly polarized radio waves. The position acquiring unit acquires information representing at least a planar position of the portable machine relative to the vehicle-mounted device. The attitude acquiring unit acquires information representing a three-dimensional attitude of the portable machine. The determining unit determines whether a wave received by the portable machine is a radio wave directly received from the vehicle-mounted device, on the basis of a characteristic relating to the direction of a magnetic field or an electric field of the radio wave received by the portable machine, and on the basis of the information representing the position and the information representing the attitude.
(FR) L'invention concerne un système de véhicule (1, 101, 201, 301) pourvu d'une machine portable (50), d'un dispositif embarqué (10), d'une unité d'acquisition de position (21, 61), d'une unité d'acquisition d'attitude (65) et d'une unité de détermination (22, 62). Le dispositif embarqué communique avec la machine portable par transmission d'ondes radio polarisées linéairement. L'unité d'acquisition de position acquiert des informations représentant au moins une position dans le plan de la machine portable par rapport au dispositif embarqué. L'unité d'acquisition d'attitude acquiert des informations représentant une attitude tridimensionnelle de la machine portable. L'unité de détermination détermine si une onde reçue par la machine portable est une onde radio directement reçue en provenance du dispositif embarqué, sur la base d'une caractéristique relative à la direction d'un champ magnétique ou d'un champ électrique de l'onde radio reçue par la machine portable, et sur la base des informations représentant la position et des informations représentant l'attitude.
(JA) 車両システム(1,101,201,301)は、携帯機(50)と車載装置(10)と位置取得部(21,61)と姿勢取得部(65)と判断部(22,62)とを備える。車載装置は、直線偏波の電波を送信することにより前記携帯機と通信する。位置取得部は、携帯機の車載装置に対する少なくとも平面的な位置を表す情報を取得する。姿勢取得部は、携帯機の3次元的な姿勢を表す情報を取得する。判断部は、携帯機が受信した電波における磁界又は電界の方向に係る特性と、前記位置を表す情報と、前記姿勢を表す情報とに基づき、携帯機の受信波が、車載装置から直接受信された電波であるか判断する。
