First Claim
1. A vehicle comprising:
- an electric power receiving coil that receives electric power, in a non-contact manner, from an electric power transmitting coil included in a power supply facility provided outside the vehicle, the electric power receiving coil being disposed at a bottom face side of the vehicle;
an image capturing device that captures an image of an outside viewed from the vehicle, the image capturing device being provided on a peripheral face of the vehicle;
a display unit that displays an outside view from the vehicle that is captured by the image capturing device; and
a guiding control portion that guides the vehicle toward the electric power transmitting coil, based on voltage of the electric power received by the electric power receiving coil, wherein;
the voltage of the electric power received by the electric power receiving coil increases as a distance between the electric power receiving coil and the electric power transmitting coil decreases;
the guiding control portion guides the vehicle so that the vehicle is stopped when a rate of change in the voltage of the received electric power becomes equal to or lower than a predetermined value; and
wherein the guiding control portion starts guiding the vehicle after an electric power transmitting unit having the electric power transmitting coil provided therein becomes positioned in a blind spot of the image capturing device.

Abstract
An electric vehicle receives electric power, in a non-contact manner, from an electric power transmitting coil provided externally to the vehicle. The electric vehicle includes an electric power receiving unit that is disposed at a bottom of the vehicle and receives electric power from the electric power transmitting unit via electromagnetic field resonance; a camera that captures an image of the outside; and a display unit that displays an outside view from the vehicle that is captured by the camera. The electric power receiving unit is disposed at a position that is offset toward a peripheral face, on which the camera is disposed, with respect to the center of the bottom in the longitudinal direction of the vehicle.
