VEHICULAR POSITION ESTIMATING SYSTEM
In this vehicular position estimating system, a plurality of vehicle-mounted communication devices (12) disposed in prescribed positions in a vehicle estimate the position of a mobile terminal relative to the vehicle, by performing wireless communication with the mobile terminal. The plurality of vehicle-mounted communication devices comprise at least three devices attached to the vehicle in mutually different locations, and each of the plurality of vehicle-mounted communication devices generates distance information indicating the distance from the vehicle-mounted communication device to the mobile terminal. The vehicular position estimating system is provided with a position coordinate calculating unit (F51) which calculates position coordinates of the mobile terminal, and an area inside/outside determining unit (F52) which determines whether the mobile terminal is present within a system operation area, wherein, if a prescribed coordinate computation condition is satisfied, the position coordinate calculating unit calculates the position coordinates of the mobile terminal, whereas if the coordinate computation condition is not satisfied, the area inside/outside determining unit determines whether the mobile terminal is present within the system operation area.
本发明提供车辆用位置推断系统。在车辆用位置推断系统中，配置于车辆的规定位置的多个车载通信器(12)通过与移动终端无线通信，来推断移动终端相对于车辆的位置。多个车载通信器为三台以上，分别安装于车辆的不同场所，多个车载通信器分别生成表示从车载通信器到移动终端的距离的距离信息。车辆用位置推断系统具备计算移动终端的位置坐标位置的坐标计算部(F51)、以及判定移动终端是否存在于系统工作区域内的区域内外判定部(F52)，在满足规定的坐标运算条件的情况下，位置坐标计算部计算移动终端的位置坐标，另一方面，在不满足坐标运算条件的情况下，区域内外判定部判定移动终端是否存在于系统工作区域内。
