Abstract

A display system of a vehicle, and a control method thereof includes: a user input device; a head-up display configured to project a virtual image including augmented reality contents and to adjust a projection position of the augmented reality contents according to predetermined driver viewpoint information and left and right direction offset; and a controller configured to correct the driver viewpoint information or the left and right direction offset according to a control input received through the user input device, wherein the left and right direction offset indicates a degree to which the augmented reality contents are shifted left or right.

First claim

What is claimed is:

1. A display system of a vehicle, the display system comprising:
a user input device;
a head-up display (HUD) configured to project a virtual image including augmented reality contents and to adjust a projection position of the augmented reality contents according to predetermined driver viewpoint information and first and second direction offset;
a controller configured to correct the driver viewpoint information or the first and second direction offset according to a control input received through the user input device; and
a display,
wherein the first and second direction offset indicates an amount to which the augmented reality contents are shifted in a first direction or a second direction,
wherein the controller is configured to display a user interface screen for correcting the driver viewpoint information and the first and second direction offset on the display and to correct the driver viewpoint information or the first and second direction offset according to the control input received while the user interface screen is displayed,
wherein the user interface screen includes at least one of graphic objects representing a driver's view state which is changed by correction of the driver viewpoint information or the first and second direction offset, and
wherein the user interface screen includes view status bars indicating a view status of a lane or a road outline shown to a driver according to the driver viewpoint information or the first and second direction offset.

2. The display system of claim 1 , wherein the first direction and the second direction are a left direction and a right direction in a setting screen of the HUD.

3. The display system of claim 1 ,
wherein the controller is configured to increase a slope of the view state bars as a height level of the driver viewpoint information increases, and to decrease the slope of the view state bars as the height level of the drive's viewpoint information decreases.

4. The display system of claim 3 ,
wherein the HUD includes a setting screen having a touch object, and
wherein, when the height level is increased in response that the driver touches the touch object in the setting screen, the controller is configured to increase the slope of the view state bars and to display the increased slope on the setting screen, and when the height level is reduced in response that the driver touches the touch object, the controller is configured to decrease the slope of the view state bars and to display the decreased slope on the setting screen.

5. The display system of claim 1 ,
wherein the controller is configured to shift the view state bars to the first direction when the first and second direction offset is adjusted to the first direction, and to shift the view state bars to the second direction when the first and second direction offset is adjusted to the second direction.

6. A method of controlling a display system that includes a head-up display (HUD) projecting augmented reality contents on a windshield glass of a vehicle, the method comprising:
displaying a user interface screen for correcting driver viewpoint information and first and second direction offset used to determine a projection position of the augmented reality contents;
correcting the driver viewpoint information or the first and second direction offset according to a control input received through a user input device; and
adjusting a projection position of the augmented reality contents based on the corrected driver viewpoint information or the corrected first and second direction offset,
wherein the first and second direction offset indicates an amount to which the augmented reality contents are shifted in a first direction or a second direction,
wherein the user interface screen includes at least one of graphic objects representing a driver's view state which is changed by correction of the driver viewpoint information or the first and second direction offset, and
wherein the user interface screen includes view status bars indicating a view status of a lane or a road outline shown to a driver according to the driver viewpoint information or the first and second direction offset.

7. The method of claim 6 , wherein the first direction and the second direction are a left direction and a right direction in a setting screen of the HUD.

8. The method of claim 6 ,
wherein a slope of the view status bar increases as a height level of the driver viewpoint information increases, and the slope decreases as the height level of the driver viewpoint information decreases.

9. The method of claim 8 ,
wherein the HUD includes a setting screen having a touch object, and
wherein, when the height level is increased in response that the driver touches the touch object in the setting screen, the controller is configured to increase the slope of the view state bars and to display the increased slope on the setting screen, and when the height level is reduced in response that the driver touches the touch object, the controller is configured to decrease the slope of the view state bars and to display the decreased slope on the setting screen.

10. The method of claim 6 ,
wherein the view state bars are shifted to the first direction when the first and second direction offset is adjusted to the first direction, and shifted to the second direction when the first and second direction offset is adjusted to the second direction.

11. A non-transitory computer readable storage medium on which a program for performing the method of claim 6 is recorded.
