POSITION DETERMINING SYSTEM AND POSITION DETERMINING METHOD
To obtain a position determining system that accurately determines whether a mobile terminal exists inside or outside a vehicle.SOLUTION: A position determining system 100 of the present disclosure includes a wireless communication device 3 installed in a vehicle and wirelessly communicating with a mobile terminal 2, a transparent radio wave selective film 11 placed in a window part 10 and selectively reflecting radio waves in a specific frequency band or attenuating them at a preset level, and a position determining device 4 mounted on the vehicle 1 and determining the position of the mobile terminal 2, in which the wireless communication device 3 includes a wireless communication unit 31 that wirelessly communicates with the mobile terminal 2, a received power measuring unit 32 that measures received in-vehicle received power, and a distance measuring unit 33 that measures a distance value to the mobile terminal based on a communication time with the mobile terminal, and the position determining device 4 includes an inside/outside vehicle determining unit 41 that determines whether the mobile terminal 2 is inside or outside the vehicle based on the normalized received power, normalized using distance values.SELECTED DRAWING: Figure 1
【課題】携帯端末が車内及び車外のいずれに存在するかを正確に判定する位置判定システムを得る。【解決手段】本開示の位置判定システム１００は、車内に搭載され、携帯端末２と無線通信する無線通信装置３と、窓部１０に配置され特定周波数帯の電波を選択的に反射または予め設定されたレベルで減衰させる透明電波選択膜１１と、車両１に搭載され携帯端末２の位置を判定する位置判定装置４と、を備え、無線通信装置３は、携帯端末２と無線通信する無線通信部３１と、受信した車内受信電力を計測する受信電力計測部３２と、携帯端末との通信時間に基づき携帯端末までの距離値を計測する距離計測部３３とを備え、位置判定装置４は、距離値を用いて車内受信電力を正規化した正規化受信電力に基づき携帯端末２が車内及び車外のいずれに存在するかを判定する車内外判定部４１と、を備える。【選択図】図１
