Abstract

A mobile terminal charging system includes: a wireless power supply device that is provided inside a vehicle cabin and that is configured to perform a charging operation for charging a mobile terminal; and a control device that controls the wireless power supply device, wherein, when wireless communication is carried out between an in-vehicle communication device and an electronic key inside the vehicle cabin in a situation that the charging operation is being performed by the wireless power supply device, the control device temporarily suppresses the charging operation performed by the wireless power supply device.

Claims

1. A mobile terminal charging system comprising:

a wireless power supply device that is provided inside a vehicle cabin and that is configured to perform a charging operation for charging a mobile terminal; and

a control device that controls the wireless power supply device, wherein

when wireless communication is carried out between an in-vehicle communication device and an electronic key inside the vehicle cabin in a situation that the charging operation is being performed by the wireless power supply device, the control device temporarily suppresses the charging operation performed by the wireless power supply device.

2. The mobile terminal charging system according to claim 1, wherein the control device temporarily stops the charging operation performed by the wireless power supply device to temporarily suppress the charging operation performed by the wireless power supply device.

3. The mobile terminal charging system according to claim 1, wherein the control device temporarily decreases an output level of electric power transferred for charging to temporarily suppress the charging operation performed by the wireless power supply device.

4. The mobile terminal charging system according to claim 3, wherein the control device temporarily decreases the output level of the transferred electric power to a level at which wireless communication between the in-vehicle communication device and the electronic key inside the vehicle cabin is not influenced.

5. The mobile terminal charging system according to claim 1, wherein the control device temporarily suppresses the charging operation performed by the wireless power supply device by transmitting a charge suppression signal to the wireless power supply device or temporarily interrupting a power supply line from an in-vehicle battery to the wireless power supply device.

6. The mobile terminal charging system according to claim 1, wherein:

a drive signal to an antenna of the in-vehicle communication device is generated at the time when a radio wave from the in-vehicle communication device toward the electronic key is transmitted;

the control device temporarily suppresses the charging operation performed by the wireless power supply device by transmitting a charge suppression signal to the wireless power supply device; and

the control device extracts the drive signal to generate the charge suppression signal.

7. The mobile terminal charging system according to claim 1, wherein:

the wireless power supply device is configured to, when a mobile terminal is placed on the wireless power supply device, execute a process of detecting and authenticating the mobile terminal in advance of the charging operation; and

the wireless power supply device does not execute the process of detecting and authenticating the mobile terminal when the charging operation is resumed after the charging operation is temporarily suppressed.

8. A mobile terminal charging method comprising:

controlling a wireless power supply device, provided inside a vehicle cabin, to perform a charging operation for charging a mobile terminal; and

when wireless communication is carried out between an in-vehicle communication device and an electronic key inside the vehicle cabin in a situation that the charging operation is being performed by the wireless power supply device, temporarily suppressing the charging operation performed by the wireless power supply device.
