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 comprising;
a plurality of electric power transmission portions configured to transmit electric power to the vehicles in a non-contact manner, andan electric power transmission control unit configured to control electric power transmission from said plurality of electric power transmission portions,said electric power transmission control unit being configured to select a first electric power transmission portion, which is not transmitting electric power, from said plurality of electric power transmission portions, and to control said selected first electric power transmission portion to transmit weak electric power when said electric power transmission control unit receives a signal requesting electric power transmission from said first vehicle,said first vehicle performing positioning using a received voltage of the weak electric power,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,said electric power transmission control unit being configured to stop transmitting said weak electric power from said first electric power transmission portion where said second vehicle is parked when the electric power transmission control unit receives said occupation signal from said second vehicle, andsaid first vehicle performing positioning, using a received voltage of the weak electric power from an electric power transmission portion where said second vehicle is not parked.

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.
