To provide a system capable of reducing frequency of useless notifications for prompting a user to remove a foreign matter that exists around a power transfer unit.SOLUTION: A displacement mode of a foreign matter is detected based on a position of the foreign matter at each of a start time and a finish time of a predetermined period. By delaying a determination timing of the displacement mode of the foreign matter by a predetermined period (predetermined time), a notification timing for prompting removal of the foreign matter can be delayed. Alternately, when it is determined that the foreign matter existing around a power transfer unit 10 is displaced, but thereafter the existence of the foreign matter is not detected, that is, in a situation in which a notification prompting a user to remove the foreign matter is unnecessary, the notification is omitted.SELECTED DRAWING: Figure 3

    【課題】送電ユニットの周囲に存在する異物の除去をユーザに促すための無駄な通知の頻度を低減しうるシステムを提供する。【解決手段】所定期間の開始時刻および終了時刻のそれぞれにおいて異物の位置に基づき、当該異物の変位態様が検知される。異物の変位態様の判定タイミングを所定期間(所定時間)分だけ遅延させることにより、当該異物の除去を促す通知タイミングを遅延させることができる。また、送電ユニット10の周囲に存在する異物が変位していると判定されたものの、その後、異物の存在が検知されない場合、すなわち、ユーザに対して異物の除去を促す通知が不要である状況では、当該通知が省略される。【選択図】図3
