POWER FEEDING SYSTEM FOR VEHICLE, ELECTRICALLY POWERED VEHICLE AND POWER FEEDING APPARATUS FOR VEHICLE
First Claim
1. A power feeding system for an electrically powered vehicle for feeding electric power from a power transferring unit of a power feeding apparatus provided outside of the electrically powered vehicle to a power receiving unit incorporated in the vehicle in a non-contact manner, the power feeding system comprising:
- first sensing means for sensing positional relation between said power transferring unit and said power receiving unit;
first guidance control means for controlling said vehicle such that said vehicle is guided to said power transferring unit based on a sensed result by said first sensing means;
second sensing means for sensing a distance between said power transferring unit and said power receiving unit based on an electric power feeding condition from said power transferring unit to said power receiving unit; and
second guidance control means for controlling said vehicle such that a position of said power receiving unit is adjusted to a position of said power transferring unit based on a sensed result by said second sensing means when said vehicle comes within a prescribed distance from said power transferring unit by said first guidance control means.

Abstract
An IPA-ECU recognizes a position of a power transferring unit by image recognition based on image information from a camera incorporated in a vehicle. Then, the IPA-ECU performs guidance control such that the vehicle is guided to the power transferring unit based on a result of the image recognition (first guidance control). A resonant ECU estimates a distance between the power transferring unit and a power receiving unit based on an electric power feeding condition from the power transferring unit to the power receiving unit. When the power transferring unit comes under a body of the vehicle, an HV-ECU performs guidance control of the vehicle such that a position of the power receiving unit is adjusted to a position of the power transferring unit based on distance information from the resonant ECU (second guidance control).

18. A power feeding apparatus for an electrically powered vehicle for feeding electric power, in a non-contact manner, to a power receiving unit incorporated in the electrically powered vehicle, the power feeding apparatus comprising:
-
a power transferring unit configured to transfer electric power received from a power supply to said power receiving unit in a non-contact manner; a communication unit for conducting communication with said vehicle; and a power control unit for controlling electric power transferred from said power transferring unit to said power receiving unit, wherein said vehicle is configured to perform adjustment of a position of said power receiving unit to a position of said power transferring unit based on an electric power feeding condition from said power transferring unit to said power receiving unit, and during reception of a signal indicating that said adjustment is being performed in said vehicle from said vehicle via said communication unit, said power control unit controls said electric power to be smaller than electric power transferred from said power transferring unit to said power receiving unit after completion of said adjustment. - View Dependent Claims (19, 21)
