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

The invention claimed is:

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;
the control unit configured to:
acquire via the antenna a radio wave status of each of a plurality of channels related to the wireless communication,
acquire a power transmission status of the wireless power transfer,
set, based on the acquired power transmission status of the wireless power transfer, switching conditions for channel switching according to the radio wave status of each of the plurality of channels related to the wireless communication,
cause channel switching based on the radio wave status of each of the plurality of channels related to the wireless communication and the switching conditions for channel switching, and
cause the wireless communication to continue on a selected channel;

wherein:
the power receiver device is mounted on a vehicle, and
when the acquired power transmission status of the wireless power transfer is a halt status of the wireless power transfer and an execution status of a positional adjustment by the vehicle with respect to the power transmitter device, the control unit sets the switching conditions for channel switching allowing an easier switch of each of the plurality of channels under a same radio wave status than in a case where the acquired power transmission status of the wireless power transfer is a halt status of both the wireless power transfer and the positional adjustment.

2. The communication control device according to claim 1 , wherein when the power transmission status is an execution status of the positional adjustment, the control unit sets the switching conditions for channel switching allowing the-easier switch of channels under the same radio wave status as a speed of the vehicle increases.

3. The communication control device according to claim 1 , wherein the control unit transmits information with respect to the acquired power transmission status of the wireless power transfer, and a status of charging by the wireless power transfer.

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

5. The communication control device according to claim 1 , wherein the selected channel is a channel which does not satisfy the switching conditions.

6. 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;
the control unit configured to:
acquire via the antenna a radio wave status of each of a plurality of channels related to the wireless communication,
acquire a power transmission status of the wireless power transfer,
set, based on the acquired power transmission status of the wireless power transfer, switching conditions for channel switching according to the radio wave status of each of the plurality of channels related to the wireless communication,
cause channel switching based on the radio wave status of each of the plurality of channels related to the wireless communication and the switching conditions for channel switching, and
cause the wireless communication to continue on a selected channel;

wherein the control unit reduces transmission power of the wireless power transfer when the radio wave status of each of the plurality of channels related to the wireless communication satisfies the switching conditions.

7. The communication control device according to claim 6 , 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 each of the plurality of 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.

8. The communication control device according to claim 6 , wherein the selected channel is a channel which does not satisfy the switching conditions for channel switching.
