Method for controlling wireless charging depending on position of FOB key
A method for controlling wireless charging depending on a position of an FOB key in a wireless charging system provided in a vehicle and including an output unit, a wireless charging mount, and a controller, includes: transmitting, by the controller, a first signal informing a peripheral region of the wireless charging mount in which a wireless charging target is mounted that wireless charging is being performed in the peripheral region of the wireless charging mount in the case in which the wireless charging starts; transmitting, by the FOB key receiving the first signal, a second signal corresponding to the first signal to the controller; stopping, by the controller receiving the second signal, the wireless charging; and informing, by the controller, a user of the vehicle that the FOB key is present in the peripheral region of the wireless charging mount through the output unit.
1. A method for controlling wireless charging depending on a position of an FOB key in a wireless charging system provided in a vehicle and including an output unit, a wireless charging mount, and a controller, comprising:
transmitting, by the controller, a first signal informing a peripheral region of the wireless charging mount in which a wireless charging target is mounted that wireless charging is being performed in the peripheral region of the wireless charging mount when the wireless charging starts;
transmitting, by the FOB key receiving the first signal, a second signal corresponding to the first signal to the controller;
stopping, by the controller receiving the second signal, the wireless charging;
informing, by the controller, a user of the vehicle that the FOB key is present in the peripheral region of the wireless charging mount through the output unit;
transmitting, by the controller, the first signal in a state in which the wireless charging is stopped after a preset time elapses after informing the user of the vehicle that the FOB key is present in the peripheral region of the wireless charging mount; and
returning to the step of informing the user of the vehicle that the FOB key is present in the peripheral region of the wireless charging mount in a case in which the second signal is again received.
2. The method for controlling wireless charging depending on a position of an FOB key according to claim 1 , wherein the first signal is a low frequency (LF) signal, and
the second signal is a radio frequency (RF) signal.
3. The method for controlling wireless charging depending on a position of an FOB key according to claim 1 , wherein the output unit is a speaker or a display provided in the vehicle, and
the controller informs the user that the FOB key is present in the peripheral region of the wireless charging mount as an audio signal through the speaker or visually informs the user that the FOB key is present in the peripheral region of the wireless charging mount through the display.
4. The method for controlling wireless charging depending on a position of an FOB key according to claim 1 , further comprising restarting the stopped wireless charging in the case in which the second signal is not received.
5. The method for controlling wireless charging depending on a position of an FOB key according to claim 1 , wherein the first signal is generated by a wireless charging coil included in the wireless charging mount and is transmitted to the peripheral region of the wireless charging mount.
6. The method for controlling wireless charging depending on a position of an FOB key according to claim 1 , wherein the second signal is a signal informing the controller that the FOB key receiving the first signal is present in the peripheral region of the wireless charging mount.
