Power receiver device, program, and control method for power receiver device

Abstract

A wireless power supply system includes a power transmitter device (20) including multiple power transmitter coils (22) and an in-vehicle power receiver device (100) including a power receiver coil (102).　 In the wireless power supply system, a power supply request signal to request power supply is transmitted from the power receiver device (100) to the power transmitter device (20), and upon receiving the power supply request signal, the power transmitter device (20) supplies power to the power receiver coil (102) in a wireless manner by energizing the power transmitter coil (22).　 The power receiver device (100) wirelessly transmits the power supply request signal from a power receiver side communication coil (170) to a power transmitter side communication coil (40 provided in the power transmitter device (20).　 The power receiver side control unit (230 acquires a relative parameter indicating a relative position or orientation of the power receiver side communication coil (170) with respect to the power transmitter side communication coil (40) in the vehicle, and adjusts an intensity of the power supply request signal based on the relative parameter.
