Power feeding system for vehicle, electrically powered vehicle and power feeding apparatus for vehicle
First Claim
1. A power feeding system comprising:
- a power feeding apparatus including a power transferring unit and a first communication unit; and
a vehicle including a power receiving device that receives electric power from the power transferring unit, and a second communication unit;
whereinthe vehicle transmits a request signal to the power feeding apparatus;
the power transferring unit starts transmitting electric power after the power feeding apparatus receives the request signal from the vehicle; and
the vehicle measures a voltage profile of a receiving electric power from the power transferring unit and checks accomplished level at fine positioning between the vehicle and the power transferring unit.

Abstract
An IPA-ECU (410) recognizes a position of a power transferring unit by image recognition based on image information from a camera (120) incorporated in a vehicle. Then, the IPA-ECU (410) 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 (460) 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 (470) 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 (460) (second guidance control).
