PROBLEM TO BE SOLVED: To provide an onboard information terminal capable of controlling notification on the basis of an outcome obtained by highly precisely discriminating a positional relationship between a current position of a vehicle and a predetermined area on a map.SOLUTION: An onboard information terminal to be mounted in a vehicle includes a positioning unit that measures the current position of the vehicle, a notification unit that performs notification using at least one of an image, light, and sounds, a first storage unit that stores the position and shape of a predetermined area on a map by means of polygonal data, a second storage unit that stores the position of the predetermined area, which indwells in a circle, according to the center position of the circle and radius, and a control unit that controls notification, which is performed by the notification unit, on the basis of relationship between the current position and the pieces of information stored in the first and second storage units. When the current position does not indwell in the predetermined area represented by the information in the first storage unit, and the current position indwells in the circle represented by the information in the second storage unit, if the center position of the circle indwells in the predetermined area, the control unit inhibits notification by the notification unit.SELECTED DRAWING: Figure 7

    【課題】車両の現在位置と地図上の所定区域との位置関係を高精度に判別した結果に基づく報知の制御が可能な車載情報端末を提供すること。【解決手段】車両に搭載される車載情報端末は、車両の現在位置を測位する測位部と、画像、光及び音の少なくとも1つを用いた報知を行う報知部と、地図上の所定区域の位置及び形状をポリゴン形式のデータによって記憶する第1記憶部と、円に内在する所定区域の位置を円の中心位置及び半径によって記憶する第2記憶部と、現在位置と第1記憶部及び第2記憶部が記憶する各情報との関係に基づき、報知部による報知を制御する制御部とを備える。制御部は、第1記憶部の情報が示す所定区域に現在位置が内在せず、かつ、第2記憶部の情報が示す円に現在位置が内在する場合、当該円の中心位置が前記所定区域に内在すれば、報知部による報知を抑止する。【選択図】図7
