NON-CONTACT ELECTRIC POWER TRANSMISSION SYSTEM, CHARGING STATION, AND VEHICLE
First Claim
1. A non-contact electric power transmission system, comprising:
- first and second vehicles; and
a charging station,said charging station includinga plurality of electric power transmission portions which can transmit electric power to the vehicles in a non-contact manner, andan electric power transmission control unit controlling electric power transmission from said plurality of electric power transmission portions,said electric power transmission control unit having a first electric power transmission portion, which is not transmitting electric power, of said plurality of electric power transmission portions transmit weak electric power when said electric power transmission control unit receives a signal requesting electric power transmission from said first vehicle,said second vehicle transmitting to said electric power transmission control unit, an occupation signal which allows determination that a parking position corresponds to said first electric power transmission portion when said second vehicle is parked at a position where the second vehicle can receive electric power from said first electric power transmission portion and when said second vehicle receives weak electric power from said first electric power transmission portion, andsaid electric power transmission control unit guiding said first vehicle to an electric power transmission portion different from said first electric power transmission portion when the electric power transmission control unit receives said occupation signal from said second vehicle.

Abstract
A charging station includes a plurality of electric power transmission portions and a power supply ECU. When a second vehicle is parked at a position where it can receive electric power from a first electric power transmission portion and when the second vehicle receives weak electric power from the first electric power transmission portion, the second vehicle transmits to the power supply ECU, an occupation signal which allows determination that the parking position corresponds to the first electric power transmission portion. When the power supply ECU receives the occupation signal of the first electric power transmission portion from the second vehicle, the power supply ECU stops transmission of weak electric power from the first electric power transmission portion and guides a first vehicle to a second electric power transmission portion.

8. A vehicle, comprising:
-
an electric power reception device which can receive electric power from a charging station in a non-contact manner; a power storage device; a charging relay provided between said electric power reception device and said power storage device; a distance sensing portion; and an electric power reception control unit controlling said charging relay and said distance sensing portion, said distance sensing portion having a resistor, and a distance sensing relay with which said resistor is connected between a pair of output lines of said electric power reception device, and said electric power reception control unit rendering said charging relay conductive and rendering said distance sensing relay non-conductive when said power storage device is charged, and rendering said charging relay non-conductive and rendering said distance sensing relay conductive after charging of said power storage device is completed.
