VEHICLE, POWER RECEIVING DEVICE, POWER TRANSMITTING DEVICE, AND CONTACTLESS POWER SUPPLY SYSTEM
First Claim
1. A vehicle that contactlessly receives electric power from a power transmitting device, comprising:
- a power receiving unit configured to contactlessly receive electric power from the power transmitting device;
an electric load configured to operate by utilizing electric power received by the power receiving unit;
a communication unit configured to carry out wireless communication with the power transmitting device, the communication unit being configured to switch a spatially communicable communication range between a first range and a second range narrower than the first range; and
a control unit configured to, at the time of identifying the power transmitting device from which electric power should be received, control the communication unit such that the communication unit communicates with the power transmitting device using the second range.

Abstract
A vehicle is able to contactlessly receive electric power from a power transmitting device and to charge a mounted electrical storage device (electric load). The vehicle includes a communication unit that carries out wireless communication with the power transmitting device and a vehicle ECU (control fit) that controls the communication unit. The communication unit is able to switch a communication range between a wide communication range (wire-area communication) and a narrow communication range (narrow-area communication). The vehicle ECU, at the time of identifying a power transmitting device from which electric power should be received, controls the communication unit such that the communication unit communicates with the power transmitting device using the narrow-area communication.

26. A contactless power supply system, comprising:
-
a power transmitting device including a power transmitting unit; a vehicle including a power receiving unit; a communication unit configured to carry out wireless communication between the power transmitting device and the vehicle, the communication unit switching a spatially communicable communication range between a first range and a second range narrower than the first range; and a control unit configured to, at the time of identifying a combination of the power transmitting device and the vehicle, control the communication unit such that the communication unit carries out communication using the second range, wherein electric power is contactlessly transferred from the power transmitting device to the vehicle.
