Abstract

The present application discloses a parking guidance system. The parking guidance system is mounted on a vehicle and includes a camera, a display device with a display correction system, a parking mode selection apparatus, a parking area selection apparatus, a first turning guidance apparatus, and a second turning guidance apparatus. The camera is mounted at the rear of the vehicle to capture the image showing environment behind the vehicle. The display device with a display correction system is coupled to the camera and is configured to display an image corrected by the display correction system. The parking mode selection apparatus is coupled to the display device. The parking mode selection apparatus displays a predicted parking area on the display device. The parking area selection apparatus is coupled to the display device. The parking area selection apparatus displays a parking guidance area on the display device. The first turning guidance apparatus is coupled to the display device. The first turning guidance apparatus displays an arc on the display device. The second turning guidance apparatus is coupled to the display device. The second turning guidance apparatus displays on the display device a parking track with distance indication.

Claims

1. A parking guidance system mounted on a vehicle, comprising:

a camera, mounted at the rear of the vehicle to capture an image showing environment behind the vehicle;

a display device with a display correction system, wherein the display device is coupled to the camera and is configured to display an image corrected by the display correction system;

a parking mode selection apparatus coupled to the display device to display a predicted parking area on the display device, wherein the predicted parking area is polygon;

a parking area selection apparatus coupled to the display device to display a parking guidance area on the display device, wherein the parking guidance area is polygon;

a first turning guidance apparatus coupled to the display device to display an arc on the display device; and

a second turning guidance apparatus coupled to the display device to display on the display device a parking track with distance indication.

2. The system of claim 1, further comprising:

a top view display apparatus coupled to the display device and further coupled to a series of detection devices which are mounted around the vehicle.

3. The system of claim 2, wherein the display correction system is a fisheye distortion correction system.

4. The system of claim 2, wherein the predicted parking area is quadrangle.

5. The system of claim 2, wherein the parking mode selection apparatus comprises a prompt apparatus coupled to the display device to detect an obstacle within the predicted parking area.

6. The system of claim 5, wherein the prompt apparatus displays the predicted parking area in a different color.

7. The system of claim 2, wherein the parking guidance area is quadrangle.

8. The system of claim 2, wherein the parking area selection apparatus comprises a guidance apparatus coupled to the display device to detect an overlap between the predicted parking area and the parking guidance area.

9. The system of claim 8, wherein the guidance apparatus displays the parking guidance area in a different color.

10. A parking guidance system mounted on a vehicle, comprising:

a camera, mounted at the rear of the vehicle to capture an image showing environment behind the vehicle;

a display device with a display correction system, wherein the display device is coupled to the camera and is configured to display an image corrected by the display correction system;

a parking mode selection apparatus coupled to the display device;

a first turning guidance apparatus coupled to the display device to display two arcs on the display device; and

a second turning guidance apparatus coupled to the display device to display on the display device a parking track with distance indication.

11. The system of claim 10, further comprising:

a top view display apparatus coupled to the display device and further coupled to a series of detection devices which are mounted around the vehicle.

12. The system of claim 11, wherein the display correction system is a fisheye distortion correction system.

13. A parking guidance system adapted to be mounted on a vehicle, said guidance system comprising:

a camera including a wide-angle optical lens, adapted for mounting adjacent the rear of the vehicle and operative to capture an image showing an environment behind the vehicle;

a vehicle operator viewable display device with a display correction system, wherein the display device is coupled to the camera and is configured to display the camera image corrected by the display correction system to substantially delete camera lens-created distortion;

a parking mode selection apparatus coupled to the display device and operative to display a predicted parking area superimposed on the image on the display device, wherein the predicted parking area is configured as a polygon;

a parking area selection apparatus coupled to the display device and operative to display a parking guidance area superimposed on the image on the display device, wherein the parking guidance area is configured as a polygon;

a first turning guidance apparatus coupled to the display device and operative to display an arc superimposed on the image on the display device; and

a second turning guidance apparatus coupled to the display device and operative to display on the display device a parking track with distance indication superimposed on the image.
