Abstract

An apparatus and method of providing road guidance based on an augmented reality head-up display (HUD) are provided. The method includes creating, by a controller, a route toward a destination and operating the augmented reality HUD to display a virtual preceding vehicle driven along the route to show that the virtual preceding vehicle is driven in front of a traveling vehicle by a reference distance.

Claims

1. An apparatus of providing road guidance based on an augmented reality head-up display (HUD), comprising:

a memory configured to store program instructions; and

a processor configured to execute the program instructions, the program instructions when executed configured to;

create a route toward a destination;

display a virtual preceding vehicle driven along the route to show that the virtual preceding vehicle is driven in front of a traveling vehicle by a reference distance; and

display a turn signal lamp of the virtual preceding vehicle at different flickering periods based on a remaining distance from a current position to left and right turn points.

2. The apparatus of providing road guidance based on an augmented reality HUD according to claim 1, wherein the program instructions when executed are further configured to:

collect a speed of the traveling vehicle, wherein the reference distance is adjusted based on the speed of the traveling vehicle.

3. The apparatus of providing road guidance based on an augmented reality HUD according to claim 2, wherein the program instructions when executed are further configured to:

display an animation on which the virtual preceding vehicle drives over a speed bump when the speed bump is present on the route.

4. The apparatus of providing road guidance based on an augmented reality HUD according to claim 3, wherein the program instructions when executed are further configured to:

display an animation showing impact that corresponds to the speed of the traveling vehicle.

5. The apparatus of providing road guidance based on an augmented reality HUD according to claim 1, wherein the program instructions when executed are further configured to:

display an animation on which the virtual preceding vehicle turns left and right when the remaining distance is within a threshold value.

6. The apparatus of providing road guidance based on an augmented reality HUD according to claim 5, wherein the program instructions when executed are further configured to:

display the virtual preceding vehicle on the animation to have a color that becomes gradually lighter in color.

7. The apparatus of providing road guidance based on an augmented reality HUD according to claim 1, wherein the program instructions when executed are further configured to:

flicker the turn signal lamp of the virtual preceding vehicle when an arrival time required for arriving at the left and right turn points from the current position is within a first threshold range; and

display an animation on which the virtual preceding vehicle turns left or right when the arrival time is within a second threshold range.

8. A method of providing road guidance based on an augmented reality head-up display (HUD), comprising:

creating, by a controller, a route toward a destination;

operating, by the controller, the augmented reality HUD to display a virtual preceding vehicle driven along the route to show that the virtual preceding vehicle is driven in front of a traveling vehicle by a reference distance; and

displaying, by the controller, a turn signal lamp of the virtual preceding vehicle at different flickering periods based on a remaining distance from a current position to left and right turn points.

9. The method of providing road guidance based on an augmented reality HUD according to claim 8, further comprising:

collecting, by the controller, a speed of the traveling vehicle, wherein the reference distance is adjusted based on the speed of the traveling vehicle.

10. The method of providing road guidance based on an augmented reality HUD according to claim 9, further comprising:

displaying, by the controller, an animation on which the virtual preceding vehicle drives over a speed bump when the speed bump is present on the route.

11. The method of providing road guidance based on an augmented reality HUD according to claim 10, further comprising:

displaying, by the controller, an animation showing impact that corresponds to the speed of the traveling vehicle.

12. The method of providing road guidance based on an augmented reality HUD according to claim 8, further comprising:

displaying, by the controller, an animation on which the virtual preceding vehicle turns left or right when the remaining distance is within a threshold value.

13. The method of providing road guidance based on an augmented reality HUD according to claim 12, further comprising:

displaying, by the controller, the virtual preceding vehicle on the animation with a color that becomes gradually lighter in color.

14. The method of providing road guidance based on an augmented reality HUD according to claim 8, further comprising:

flickering, by the controller, the turn signal lamp of the virtual preceding vehicle when an arrival time required for arriving at the left and right turn points from the current position is within a first threshold range; and

displaying, by the controller, an animation on which the virtual preceding vehicle turns left or right when the arrival time is within a second threshold range.
