PROBLEM TO BE SOLVED: To provide a technique capable of accurately detecting positional relation between a vehicle and a notification object even if the notification object is at a position which cannot be seen directly from the vehicle.SOLUTION: An on-vehicle device 10 mounted on a vehicle is a position detection device that communicates with a mobile terminal 110 of a terminal owner B around the vehicle by radio and detects the relative position of the mobile terminal 110. The on-vehicle device 10 comprises: a GNSS signal reception circuit 45 that receives a GNSS signal Sg transmitted by a positioning satellite PS; a radio communication circuit 41 that receives terminal position information from the mobile terminal 110; and a mobile communication circuit 43 that receives a correction signal Sc to correct a positioning signal. The on-vehicle device 10 corrects the GNSS signals Sg received by both of the mobile terminal 110 and the GNSS signal reception circuit 45 by using the correction signal, and calculates the positional relation of the mobile terminal 110 to the vehicle A from the vehicle position information and the terminal position information on the basis of the corrected GNSS signals Sg.SELECTED DRAWING: Figure 2

    【課題】車両から直接的に見えない位置に報知対象者が居る場合でも、車両と報知対象者の位置関係を高精度に検出可能な技術の提供。【解決手段】車両に搭載された車載器10は、車両周囲の端末所持者Bの携帯端末110と無線通信を行うことにより、当該携帯端末110の相対位置を検出する位置検出装置である。車載器10は、測位衛星PSから送信されるGNSS信号Sgを受信するGNSS信号受信回路45、端末位置情報を携帯端末110から受信する無線通信回路41、測位信号を補正するための補正信号Scを受信するモバイル通信回路43を備えている。車載器10は、補正信号を用いて携帯端末110及びGNSS信号受信回路45のそれぞれにて受信されたGNSS信号Sgを補正し、補正したGNSS信号Sgに基づく車両位置情報及び端末位置情報から車両Aに対する携帯端末110の位置関係を算出する。【選択図】図2
