To provide a position determination system and a position determination method that can improve the accuracy of position determination of a terminal.SOLUTION: A vehicle 1 includes a position determination system 30 that determines a position of a terminal 2 carried by a user with respect to the vehicle. The position determination system includes a position determination unit 31 that determines the position of the terminal 2 based on reception intensity data for each communication unit 10 obtained by a reception intensity measured for a radio wave of each frequency regarding a plurality of radio waves transmitted at different frequencies between a plurality of communication units 10 and the terminal 2. The communication units 10 are provided on both of two division portions into which the vehicle 1 is divided along a reference direction set in the vehicle 1.SELECTED DRAWING: Figure 1

    【課題】端末の位置判定の精度を向上可能にした位置判定システム及び位置判定方法を提供する。【解決手段】車両1は、ユーザに所持される端末2の車両に対する位置を判定する位置判定システム30が備えている。複数の通信部10と端末2との間で、異なる周波数で送信された複数の電波について、各周波数の電波ごとに測定された受信強度により求まる通信部10ごとの受信強度データに基づいて、端末2の位置を判定する位置判定部31を備えている。通信部10は、車両1に設定された基準方向に沿って車両1を分割した2つの分割部分の両方に設けられている。【選択図】図1
