Abstract

Disclosed is a method of guiding wireless charging of an electric vehicle. The method includes recognizing, by a controller, an entrance of the electric vehicle into a parking slot for charging, displaying, by the controller, an around view monitor (AVM) image, the AVM image including a position of an inductive power reception module mounted in the electric vehicle and a position of an inductive power transmission module drawn on the parking slot for charging and, when the position of the inductive power reception module is aligned with the position of the inductive power transmission module, informing, by the controller, a driver about alignment of the positions of the inductive power reception module and the inductive power transmission module.

Claims

1. A method of guiding wireless charging of an electric vehicle, the method comprising:

recognizing, by a controller, an entrance of the electric vehicle into a parking slot for charging the electric vehicle;

displaying, by the controller, an around view monitor (AVM) image, wherein the AVM image includes a position of an inductive power reception module mounted in the electric vehicle and a position of an inductive power transmission module drawn on the parking slot for charging;

displaying, by the controller, a moving guide line to align the position of the inductive power reception module with the position of the inductive power transmission module; and

when the position of the inductive power reception module is aligned with the position of the inductive power transmission module, informing, by the controller, a driver about alignment of the positions of the inductive power reception module and the inductive power transmission module.

2. The method of claim 1, wherein the recognizing of the entrance includes:

recognizing an indicator informing of the parking slot for charging in the AVM image.

3. The method of claim 1, wherein the recognizing of the entrance includes:

recognizing the entrance of the electric vehicle into the parking slot for charging based on global positioning system (GPS) information.

4. The method of claim 1, wherein the recognizing of the entrance includes:

recognizing the entrance of the electric vehicle into the parking slot for charging through a manual input by the driver.

5. The method of claim 1, wherein the displaying of the AVM image includes:

displaying a moving guide line to align the position of the inductive power reception module with the position of the inductive power transmission module.

6. The method of claim 1, further including:

outputting voice guidance to align the position of the inductive power reception module with the position of the inductive power transmission module.

7. The method of claim 1, further including:

displaying a graphic image generated corresponding to a position of the parking slot when the parking slot for charging is covered by the electric vehicle while the position of the inductive power reception module is being aligned with the position of the inductive power transmission module.

8. A method of guiding wireless charging of an electric vehicle, the method comprising:

recognizing, by a controller, an entrance of the electric vehicle into a parking slot for charging the electric vehicle;

detecting, by the controller, a position of an inductive power transmission module based on indicators drawn on the parking slot;

displaying, by the controller, an around view monitor (AVM) image, wherein the AVM image includes a position of an inductive power reception module mounted in the electric vehicle and the detected position of the inductive power transmission module;

displaying a moving guide line to align the position of the inductive power reception module with the position of the inductive power transmission module; and

when the position of the inductive power reception module is aligned with the position of the inductive power transmission module, informing, by the controller, a driver about alignment of the positions of the inductive power reception module and the inductive power transmission module.

9. The method of claim 8, wherein the recognizing of the entrance includes recognizing an indicator informing of the parking slot for charging in the AVM image.

10. The method of claim 8, wherein the recognizing of the entrance includes:

recognizing the entrance of the electric vehicle into the parking slot for charging based on global positioning system (GPS) information.

11. The method of claim 8, wherein the recognizing of the entrance includes:

recognizing the entrance of the electric vehicle into the parking slot for charging through a manual input by the driver.

12. The method of claim 8, wherein the position of the inductive power transmission module is a center between the indicators.

13. The method of claim 8, wherein the displaying of the AVM image includes:

displaying a moving guide line and a guide character to align the position of the inductive power reception module with the position of the inductive power transmission module.

14. The method of claim 8, further including:

outputting voice guidance to align the position of the inductive power reception module with the position of the inductive power transmission module.
