ON-VEHICLE DEVICE, POSITION ESTIMATION METHOD AND COMPUTER PROGRAM
To provide an on-vehicle device, a position estimation method and a computer program capable of estimating correctly, a position of a radio terminal.SOLUTION: An on-vehicle device 10 wirelessly sends a request signal for requesting sending of a response signal to a radio terminal 20 and wirelessly receives the response signal from the radio terminal 20. The on-vehicle device 10 acquires relative position data indicating a relative position of the radio terminal 20 in which a reception position of the radio terminal 20 which received the request signal is set as a reference. In addition, the on-vehicle device 10 determines a reference position of the radio terminal 20 in which a position of the vehicle 100 is set as a reference, when receiving the response signal. The on-vehicle device 10 estimates a position of the radio terminal 20 in which the position of the vehicle 100 is set as a reference, based on a relative position indicated by the acquired relative position data and determined reference position.SELECTED DRAWING: Figure 1
【課題】無線端末の位置を正確に推定することができる車載装置、位置推定方法及びコンピュータプログラムを提供することにある。【解決手段】車載装置１０は、無線端末２０に応答信号の送信を要求する要求信号を無線で送信し、無線端末２０から応答信号を無線で受信する。車載装置１０は、要求信号を受信した無線端末２０の受信位置を基準とした無線端末２０の相対位置を示す相対位置データを取得する。更に、車載装置１０は、応答信号を受信した場合に、車両１００の位置を基準とした無線端末２０の基準位置を決定する。車載装置１０は、取得した相対位置データが示す相対位置と決定した基準位置とに基づいて、車両１００の位置を基準とした無線端末２０の位置を推定する。【選択図】図１
