1. A foreign object detecting system comprising:
a foreign object detecting section configured to detect that a foreign object is present around a power transmitting unit transmitting power to a power receiving unit of a vehicle in a non-contact manner to charge a battery of the vehicle;
a foreign object displacement detecting section configured to detect a displacement mode of the foreign object whose presence is detected by the foreign object detecting section; and
a notifying section configured to control a mode of notification to a user of the vehicle via an external terminal in accordance with the displacement mode detected by the foreign object displacement detecting section, the notification recommending that the user of the vehicle remove the foreign object,
wherein the foreign object displacement detecting section detects the displacement mode of the foreign object by determining whether speed of displacement of the foreign object is zero or not, detects the displacement of the foreign object in a case when the speed of displacement of the foreign object is not zero, and not detect the displacement of the foreign object in a case when the speed of displacement of the foreign object is zero,
wherein the foreign object displacement detecting section determines whether a predetermined time has elapsed while detecting the speed of displacement of the foreign object is not zero, and
in a case when it is determined that the speed of displacement of the foreign object is zero before the predetermined time has elapsed, the notifying section provides the notification to the user.
