Abstract

A communication control device comprises: an antenna; and a control unit that controls wireless communication related to wireless power transfer to a power receiver device through a power transmitter device. The control unit acquires via the antenna a radio wave status of each of a plurality of channels related to the wireless communication. The control unit acquires a power transmission status of the wireless power transfer. The control unit sets, based on the acquired power transmission status, switching conditions for switching the channel according to the radio wave status. The control unit causes the channel to be switched based on the radio wave status and the switching conditions. The control unit causes the wireless communication to continue on the switched channel.

First claim

1 . A communication control device comprising:
an antenna; and a control unit controlling wireless communication related to wireless power transfer to a power receiver device through a power transmitter device, wherein the control unit acquires via the antenna a radio wave status of each of a plurality of channels related to the wireless communication, acquires a power transmission status of the wireless power transfer, sets, based on the acquired power transmission status, switching conditions for switching the channel according to the radio wave status, causes the channel to be switched based on the radio wave status and the switching conditions, and causes the wireless communication to continue on the switched channel.

2 . The communication control device according to claim 1 , wherein when the power transmission status is an execution status of the wireless power transfer, the control unit sets the switching conditions allowing an easier switch of the channels under the same radio wave status than in a case where the power transmission status is a halt status of the wireless power transfer.

3 . The communication control device according to claim 1 , wherein
the power receiver device is mounted on a vehicle, and when the power transmission status is a halt status of the wireless power transfer and when the power transmission status is an execution status of positional adjustment by the vehicle with respect to the power transmitter device, the control unit sets the switching conditions allowing an easier switch of the channels under the same radio wave status than in a case where the power transmission status is a halt status of the positional adjustment.

4 . The communication control device according to claim 3 , wherein when the power transmission status is an execution status of the positional adjustment, the control unit sets the switching conditions allowing an easier switch of the channels under the same radio wave status as a speed of the vehicle increases.

5 . The communication control device according to claim 1 , wherein the control unit reduces transmission power of the wireless power transfer when the radio wave statuses of all the channels satisfy the switching conditions.

6 . The communication control device according to claim 1 , wherein the control unit transmits information on any one of the radio wave status, the power transmission status, the channel on which the wireless communication is being continued, the channel to be switched, and a status of charging by the wireless power transfer.
