VEHICLE POSITION DETERMINATION SYSTEM
To provide a position determination system for a vehicle capable of reducing the possibility of erroneous determination of the position of a portable terminal.SOLUTION: The on-vehicle system includes an external communication device 12 for performing wireless communication (that is, short distance communication) directly with a portable terminal 90 located outside the vehicle and the portable terminal, and an in-vehicle communication device 13 for near field communication with portable terminal 90 and portable terminal existing in the vehicle compartment. The outdoor communication device 12 is disposed in the middle of the surface of a metal B pillar 24B facing the outdoor. an in-vehicle communication device 13 is disposed near the center console. When the strength outside the vehicle is higher than the strength inside the vehicle, the position determination unit determines that the portable terminal is present outside the vehicle.SELECTED DRAWING: Figure 6
【課題】携帯端末の位置を誤判定する恐れを低減可能な車両用位置判定システムを提供する。【解決手段】車載システムは、車室外に存在する携帯端末９０と携帯端末と直接的に無線通信（つまり近距離通信）するための車室外通信機１２と、車室内に存在する携帯端末９０と携帯端末と近距離通信するための車室内通信機１３とを備える。車室外通信機１２は、金属製のＢピラー２４Ｂの車室外に向いている面の中段部に配置されている。また、車室内通信機１３は、センターコンソール付近に配置されている。位置判定部は、車室外強度が車室内強度よりも高い場合には、携帯端末は車室外に存在すると判定する。【選択図】図６
