PROBLEM TO BE SOLVED: To provide a user discrimination system capable of accurately identifying a driver even when plural portable terminals are present in the surrounding of a vehicular portable tool, and the vehicular portable tool.SOLUTION: A vehicular portable tool 200 executes scan processing multiple times at different time points, and detects a portable terminal(s) 300 present in the surrounding of the tool on the basis of reception of a predetermined trigger signal from an on-vehicle machine 100, and acquires reception signal intensity of a signal sent from the respective portable terminal(s) 300. Then, based on a result of the scan processing of multiple times, the portable terminal 300, in which change degree of the reception signal intensity is smallest, is determined as a driver terminal.SELECTED DRAWING: Figure 1
【課題】車両用携帯機の周辺に複数の携帯端末が存在する場合であっても、より精度良くドライバを特定できるユーザ識別システム、及び車両用携帯機を提供する。【解決手段】車両用携帯機200は、車載機100から所定のトリガ信号を受信したことに基づいて、異なる時点においてスキャン処理を複数回実施し、自機周辺に存在する携帯端末300を検出するとともに、各携帯端末300から送信される信号の受信信号強度を取得する。そして、その複数回のスキャン処理の結果、最も受信信号強度の変化度合いが小さい携帯端末300を、ドライバ端末と決定する。【選択図】図1
