Abstract

A vehicle wireless charging guidance system and method are provided. The system includes a power transmission module, which is installed in a charging station and configured to receive a voltage and switch a transmission coil, a power reception module, which is installed in a vehicle and configured to switch energy transmitted from the power transmission module so as to correspond to a battery arranged in the vehicle, and an around view monitoring unit, which is arranged in the vehicle and configured to receive position information of the power transmission module form the power transmission module and position information of the power reception module from the power reception module, and display the received position information of the power transmission module and the received position information of the power reception module and image information around the vehicle.

Claims

1. A vehicle wireless charging guidance system, comprising:

a power transmission module, which is installed in a charging station and configured to receive a voltage and switch a transmission coil;

a power reception module, which is installed in a vehicle and configured to switch energy transmitted from the power transmission module so as to correspond to a battery arranged in the vehicle; and

an around view monitoring unit, which is arranged in the vehicle and configured to receive position information of the power transmission module from the power transmission module and position information of the power reception module from the power reception module, and display the received position information of the power transmission module, the received position information of the power reception module, and image information around the vehicle.

2. The vehicle wireless charging guidance system of claim 1, wherein the power transmission module transmits wireless communication state information, charging state information, the position information of the power transmission module to the power reception module.

3. The vehicle wireless charging guidance system of claim 2, wherein the power reception module transmits the position information of the power transmission module received from the power transmission module and the position information of the power reception module to the around view monitoring unit.

4. The vehicle wireless charging guidance system of claim 3, wherein the around view monitoring unit displays the image information around the vehicle obtained from a camera sensor arranged in the vehicle, and the position information of the power transmission module and the position information of the power reception module, according to movement of the vehicle, and displays a completion message when a matching degree of position of the power transmission module and position of the power reception module is equal to or more than a predetermined value.

5. The vehicle wireless charging guidance system of claim 2, wherein the around view monitoring unit displays charging amount information, estimated charging efficiency information, estimated charging time information of the battery transmitted from the power reception module.

6. The vehicle wireless charging guidance system of claim 1, further comprising:

a navigation unit configured to display charging state information transmitted from the power reception module, and display a charging power setting tap.

7. The vehicle wireless charging guidance system of claim 1, further comprising:

a parking assistance system (PAS) configured to move the vehicle so that the power reception module arranged in the vehicle corresponds to the power transmission module using the position information of the power transmission module when a charging command signal is received.

8. A vehicle wireless charging guidance method, comprising:

(a) obtaining position information of a power transmission module which is installed in a charging station and configured to receive a voltage and switch a transmission coil, and position information of a power reception module, which is installed in a vehicle and configured to receive energy from the power transmission module;

(b) obtaining image information around the vehicle according to movement of the vehicle, and obtaining around view information; and

(c) displaying the position information of the power transmission module and the position information of the power reception module, and the around view information.

9. The vehicle wireless charging guidance method of claim 8, after the operation (c), further comprising:

displaying a completion message when a matching degree of the power transmission module and the power reception module changed according to the movement of the vehicle is equal to or more than a predetermined value.

10. The vehicle wireless charging guidance method of claim 8, after the operation (c), further comprising:

displaying charging amount information, estimated charging efficiency information, estimated charging time information of the battery transmitted from the power reception module.
