PROBLEM TO BE SOLVED: To detect with sensitivity, a portable terminal which is left behind.SOLUTION: An on-vehicle device is an on-vehicle device which is mounted on a vehicle and is connected to a portable terminal in radio communication, and comprises: an occupant getting-off determination part for determining that, an occupant of the vehicle has gotten off from the vehicle; a radio communication part capable of changing signal intensity of a radio signal which is transmitted to the portable terminal between first intensity and second intensity which is weaker than the first intensity and for performing radio communication with the portable communication by using radio signal; a connection state confirmation part for confirming a connection state with the portable terminal; a notification part for notifying a user of the portable terminal being left behind on the vehicle; and a control part for, when the signal intensity of the radio communication part is changed from the first intensity to the second intensity, it is confirmed that the portable terminal is connected by the connection state confirmation part, and it is determined that the occupant has gotten off from the vehicle by the occupant getting-off determination part, notifying using the notification part.SELECTED DRAWING: Figure 1
【課題】感度よく携帯端末の置忘れを検出する。【解決手段】車載装置は、車両に搭載され、携帯端末と無線通信で接続される車載装置であって、車両の乗員が車両から降車したことを判定する乗員降車判定部と、携帯端末へ送信する無線信号の信号強度を第1の強度と第1の強度よりも弱い第2の強度との間で変更可能であり、無線信号を用いて携帯端末と無線通信を行う無線通信部と、携帯端末との接続状態を確認する接続状態確認部と、携帯端末の車両への置忘れを報知する報知部と、無線通信部の信号強度が第1の強度から第2の強度に変更された場合において、接続状態確認部によって携帯端末が接続された状態と確認され、かつ乗員降車判定部によって乗員が降車したと判定されると、報知部を用いて報知する制御部とを備える。【選択図】図1
