Abstract

A system and method for controlling a head lamp for a vehicle are provided. The system includes a first head lamp that is configured to block a part of a first light emitted from a first light source to form a first shaded line on a front road of a vehicle. In addition, a second head lamp is configured to block a part of a second light emitted from a second light source to form a second shaded line on the front road of the vehicle.

First claim

What is claimed is:

1. A system for controlling a head lamp for a vehicle, comprising:
a first head lamp configured to block a part of a first light emitted from a first light source to form a first shaded line on a front road of a vehicle; and
a second head lamp configured to block a part of a second light emitted from a second light source to form a second shaded line on the front road of the vehicle,
wherein a distance between the first shaded line and the second shaded line is based on a vehicle width; and
wherein the first shaded line that extends from the first light source and the second shaded line that extends from the second light source are formed to extend a predetermined distance from the vehicle.

2. The system of claim 1 , further comprising:
a controller configured to operate the first head lamp and the second head lamp,
wherein the first shaded line and the second shaded line are formed or released by a control signal of the controller.

3. The system of claim 1 , wherein the first head lamp and the second head lamp configure a left head lamp and a right head lamp of the vehicle, respectively.

4. The system of claim 1 , wherein the first shaded line and the second shaded line are formed when the first head lamp and the second head lamp are turned on.

5. The system of claim 1 , further comprising:
a shaded line adjusting switch operated by the controller,
wherein the first shaded line and the second shaded line are formed when the shaded line adjusting switch is turned on, and the first shaded line and the second shaded line are removed when the shaded line adjusting switch is turned off.

6. The system of claim 1 , wherein the first shaded line and the second shaded line are formed when the vehicle is driven at a predetermined speed or less.

7. The system of claim 1 , wherein the first shaded line and the second shaded line are formed when the illuminance of the exterior of the vehicle is a predetermined illuminance or less.

8. The system of claim 1 , wherein the first shaded line and the second shaded line are formed in conjunction with a light distribution pattern in one mode of a plurality of modes of an adaptive front lighting system.

9. A system for controlling a head lamp for a vehicle, comprising:
a first head lamp configured to form a high beam light distribution pattern at a front side of a vehicle; and
a second head lamp configured to form a low beam light distribution pattern at the front side of the vehicle,
wherein the second head lamp forms a pair of shaded lines in a part of the low beam light distribution pattern,
wherein a distance between the pair of shaded lines is based on a vehicle width; and
wherein the pair of shaded lines extend from the second headlamp and are formed to extend a predetermined distance from the vehicle.

10. The system of claim 9 , further comprising:
a controller configured to operate the second head lamp,
wherein the pair of shaded lines are formed or released by a control signal of the controller.

11. The system of claim 9 , wherein the pair of shaded lines are formed when the second head lamp is turned on.

12. The system of claim 11 , further comprising:
a shaded line adjusting switch operated by the controller,
wherein the pair of shaded lines are formed when the second head lamp is turned on and the shaded line adjusting switch is turned on, and the pair of shaded lines are removed when the shaded line adjusting switch is turned off.

13. The system of claim 9 , wherein the pair of shaded lines are formed when the vehicle is driven at a predetermined speed or less.

14. The system of claim 9 , wherein the pair of shaded lines are formed when the illuminance of the exterior of the vehicle is a predetermined illuminance or less.

15. The system of claim 9 , wherein the pair of shaded lines are formed in conjunction with a light distribution pattern in one mode of a plurality of modes of an adaptive front lighting system.

16. A method of controlling a head lamp of a vehicle, the method comprising:
determining, by a controller, a vehicle width;
adjusting, by the controller, positions of light blocking bodies disposed at front sides of light sources based on the vehicle width; and
irradiating, by the controller, light from the light sources,
wherein a part of the light is blocked to form a pair of shaded lines spaced apart from each other based on the same distance as the vehicle width; and
wherein the pair of shaded lines extend from the light source are formed to extend a predetermined distance from the vehicle.

17. The method of claim 16 , further comprising:
turning on, by the controller, a shaded line adjusting switch to form the pair of shaded lines; and
turning off, by the controller, the shaded line adjusting switch to remove the pair of shaded lines.

18. The method of claim 16 , wherein the pair of shaded lines are formed when the vehicle is driven at a predetermined speed or less.
