4 is a flowchart illustrating a method of controlling a wireless power transmitting / receiving device for a vehicle according to a first embodiment of the present invention.

Referring to FIG. 4, the controller 130 of the wireless power transmission / reception apparatus for a vehicle according to the present exemplary embodiment detects the type of the electronic device and the location where the electronic device is installed in order to adjust the size of wireless transmission power for each direction in which the electronic device is installed.

Therefore, the electric equipment requiring the small power may be driven by wirelessly receiving power set to a minimum size (eg, the first power size) in the vehicular wireless power transmission / reception apparatus. The vehicle wireless power transceiver may be driven by wirelessly receiving power set to a maximum size (for example, the second power size). That is, there may be a difference in the magnitude of power (that is, required power) driven for each electric appliance.

Therefore, when the vehicle wireless power transmission and reception apparatus increases and transmits power in a predetermined unit from a minimum power to a maximum power, it may be driven from an electric device having a small amount of the required power. The electronic device driven as described above outputs a specific signal (eg, charging signal, Ack signal, type or ID signal of electronic device, electronic device information, etc.).

As described above, the process of recognizing the electrical equipment installed in the vehicle through a scan (S101 ~ S105) may be automatically performed at the start of the vehicle, or may be performed according to the driver's instructions.

In addition, the controller 130 recognizes the type of the electronic device based on a specific signal received by communicating with the electronic device (for example, a charging signal, an Ack signal, a type or ID signal of the electronic device, information of the electronic device, etc.) (S107).

In addition, the control unit 130 stores the type and direction information of the electrical equipment recognized in the step S106 and step S107 in the form of a look-up table (S108).

The controller 130 wirelessly transmits power having a magnitude greater than or equal to the required power of the electronic device in a direction corresponding to the type of the electronic device, based on the information stored in the lookup table (S109).

The process described with reference to FIG. 4 may also be performed in the vehicular wireless power transceiver (ie, the second power transceiver) according to the second embodiment of the present invention.

5 is a flowchart illustrating a method of controlling a wireless power transmission / reception device for a vehicle according to a second embodiment of the present invention.

Hereinafter, a vehicular wireless power transceiver (ie, a second power transceiver) according to a second embodiment of the present invention will be described with reference to FIG. 5. A method of receiving and operating power wirelessly transmitted from a transceiver device) will be described.

The second power transceiver performs wireless power transmission by receiving power transmitted wirelessly from the first power transceiver, and has a size adjusted for each direction specified by the power transmission coils 111, 112, 113, and 114. Power transfer can be performed.

Accordingly, the control unit 130 of the second power transmission and reception device receives the wirelessly transmitted power (S201) and supplies the received power to the equalizing device to turn on the equalizing device 180, and stores the received power in the power storage unit. In operation S202, it is stored in 160.

As described in step S109, the controller 130 uses the power stored in the power storage unit 160 based on the information stored in the lookup table, and the electronic device controls the electronic device in a direction corresponding to the type of the electronic device. Wirelessly transmits a power having a size greater than the required power (S203).

In addition, the controller 130 checks the remaining power of the power storage unit 160, and based on the power consumption per hour, the remaining power of the power storage unit 160 as a power supply time (or power transfer time). In conversion, when the power transmission possible time is equal to or less than a specified reference (YES in S204), an alarm signal is transmitted to the first power transceiver (S205).

Accordingly, the control unit 130 of the first power transmission and reception device outputs an alarm signal (for example, the state of the second power transmission and reception device) through the AVN device of the vehicle (S206).

Accordingly, the controller 130 of the first power transceiver may increase and transmit the amount of power transmitted to the second power transceiver, or limit the amount of power transmitted by the second power transceiver. have.

Hereinafter, a method of operating the first and second power transceivers when the power transmission possible time in the second power transceiver is less than or equal to a predetermined reference will be described.

Accordingly, the control unit 130 of the second power transmission and reception device withdraws the type and direction information of the corresponding electrical equipment (that is, the electrical equipment to limit the power transmission) from the look-up table stored in the internal memory (not shown) (S302).

In addition, the controller 130 of the second power transmission / reception apparatus checks whether another electronic device is installed within a specified range of a direction in which the corresponding electronic device (that is, the electronic device to limit power transmission) drawn from the lookup table is installed (S303).

As a result of the check (S303), when no other electronic device is installed within a specified range of the direction in which the corresponding electronic device (that is, the electronic device to limit power transmission) is installed (No in S303), the electronic device (that is, the power transmission is limited) The electric power transmission coil corresponding to the direction in which the electric equipment is installed is turned off (S306).

However, as a result of the check (S303), when another electronic device is installed within a specified range of the direction in which the corresponding electronic device (that is, the electronic device to limit power transmission) is installed (YES in S303), the controller 130 of the second power transmission / reception device ) Transmits the state information (that is, information indicating that the electric power cannot be limited because other electric appliances are installed in the direction in which the electric appliances limiting the power transmission are installed) to the control unit 130 of the first power transmission / reception apparatus ( S304).

Accordingly, the control unit 130 of the first power transmission / reception device may limit power because other electronic devices are installed in a direction in which the electronic device has a state information (that is, the electronic device which limits the power transmission) is installed through an AVN (Audio Video Navigation) device of the vehicle. Information indicating that the status can not be output) (S305).

This allows the driver to manually turn off the device (i.e., the device to limit power transmission), thereby reducing the power to be transmitted by the second power transceiver when the device is no longer transmitting power. Allow or block.
