Abstract

A vehicular system mounted to a vehicle includes: a power-feeding device that wirelessly feeds power to a power-feeding object device; a communication device that performs wireless communication with a predetermined portable device; and a control device that controls to stop a power-feeding operation of the power-feeding device when the communication device performs wireless communication with the portable device.

Claims

1. A vehicular system mounted to a vehicle, comprising:

a power-feeding device that feeds power wirelessly to a power-feeding object device;

a communication device that performs wireless communication with a predetermined portable device; and

a control device that transmits a control signal, which controls a power-feeding operation performed by the power-feeding device to stop when the communication device performs the wireless communication with the portable device;

wherein the power-feeding device initiates the power-feeding operation subsequent to a predetermined time period, which has elapsed from stopping transmission of the control signal from the control device;

wherein the power-feeding device continues to stop the power-feeding operation when the transmission of the control signal is restarted prior to an elapse of the predetermined time period;

wherein the communication device reattempts the wireless communication up to a predetermined maximum number of times when the wireless communication with the portable device is not successful;

wherein the control device stops the transmission of the control signal when the wireless communication is completed; and

wherein the control device restarts the transmission of the control signal prior to the elapse of the predetermined period from the stopping transmission of the control signal when the wireless communication is reattempted.

2. The vehicular system according to claim 1,

wherein the control device stops the transmission of the control signal after the wireless communication is successful or reattempt reaches the predetermined maximum number of times.

3. A communication apparatus mounted to a vehicle, comprising:

a communication device that performs wireless communication with a predetermined portable device; and

a control device that transmits a control signal to stop a power-feeding operation performed by a power-feeding device, which feeds power wirelessly to a power-feeding object device, when the communication device performs the wireless communication with the portable device;

wherein the power-feeding device initiates the power-feeding operation subsequent to a predetermined time period, which has elapsed from stopping transmission of the control signal from the control device;

wherein the power-feeding device continues to stop the power-feeding operation when the transmission of the control signal is restarted prior to an elapse of the predetermined time period;

wherein the communication device reattempts the wireless communication up to a predetermined maximum number of times when the wireless communication with the portable device is not successful;

wherein the control device stops the transmission of the control signal when the wireless communication is completed; and

wherein the control device restarts the transmission of the control signal prior to the elapse of the predetermined period from the stopping transmission of the control signal when the wireless communication is reattempted.

4. A power-feeding device for feeding power wirelessly to a power-feeding object device,

wherein the power-feeding device stops a power-feeding operation in response to a predetermined control signal received from a communication apparatus for communicating with the power-feeding device, and starts the power-feeding operation subsequent to a predetermined time period, which has elapsed from stopping transmission of the control signal from the communication apparatus;

wherein the power-feeding device continues to stop the power-feeding operation when the transmission of the control signal is restarted prior to an elapse of the predetermined time period;

wherein the communication apparatus reattempts the wireless communication up to a predetermined maximum number of times when the wireless communication is not successful;

wherein the communication apparatus stops the transmission of the control signal when the wireless communication is completed; and

wherein the communication apparatus restarts the transmission of the control signal prior to the elapse of the predetermined period from the stopping transmission of the control signal when the wireless communication is reattempted.

5. A non-transitory tangible computer-readable storage medium comprising instructions for execution by a computer, the instructions including a method being computer implemented, the method including:

feeding power wirelessly to a power-feeding object device;

performing wireless communication with a portable device;

transmitting a control signal to stop the feeding of power wirelessly to the power-feeding object device when performing the wireless communication with the portable device;

initiating a power-feeding operation subsequent to a predetermined time period, which has elapsed from stopping transmission of the control signal;

continuing to stop the power-feeding operation when restarting the transmission of the control signal prior to an elapse of the predetermined time period;

reattempting the wireless transmission up to a predetermined maximum number of times when the wireless communication with the portable device is not successful;

stopping the transmission of the control signal when the wireless communication is completed; and

restarting the transmission of the control signal prior to the elapse of the predetermined time period from the stopping transmission of the control signal when the wireless communication is reattempted.
