FOREIGN MATTER SENSING DEVICE AND NON-CONTACT ELECTRIC-POWER TRANSFER SYSTEM
First Claim
1. A foreign matter sensing device that detects a foreign matter between a vehicle-side coil, which is used when a battery equipment mounted to a vehicle is charged and discharged, and an out-of-vehicle coil which performs a non-contact electric-power transfer with the vehicle-side coil, the foreign matter sensing device comprising:
- an imaging portion that images an image of a foreign matter detection range above the out-of-vehicle coil;
a first determiner that determines whether there is a foreign matter in the foreign matter detection range based on the image imaged by the imaging portion;
a temperature sensor that senses a temperature of the foreign matter detection range; and
a second determiner that determines whether there is a foreign matter in the foreign matter detection range based on the temperature sensed by the temperature sensor, whereinthe second determiner executes determining whether there is a foreign matter in the foreign matter detection range while electric-power is transferred between the vehicle-side coil and the out-of-vehicle coil, when the first determiner determines that there is no foreign matter after the imaging portion images the image of the foreign matter detection range in response to a start demand instructing to start transferring electric-power.

Abstract
A foreign matter sensing device includes a first determiner that determines whether there is a foreign matter in a foreign matter detection range based on an image imaged by an imaging portion, and a second determiner that determines whether there is a foreign matter in the foreign matter detection range based on a temperature sensed by a temperature sensor. The second determiner executes determining whether there is a foreign matter in the foreign matter detection range while electric-power is transferred between a vehicle-side coil and an out-of-vehicle coil, when the first determiner determines that there is no foreign matter after the imaging portion images the image of the foreign matter detection range in response to a start demand instructing to start transferring electric-power.
