First Claim
Patent Images
1. A head lamp apparatus of an automobile, comprising:
- a left headlight disposed at a front-left side of the automobile configured to direct light in front of the automobile;
a right headlight disposed at a front-right side of the automobile configured to direct light in front of the automobile;
an automobile speed sensing sensor configured to sense a driving speed of the automobile;
a global positioning system (GPS) receiving unit configured to receive a driving position of the automobile;
a controller configured to rotate one of the left headlight and the right headlight to direct light toward a curved road when the driving position of the automobile received by the GPS receiving unit is an approximate predetermined driving time prior to the automobile turning with the curved road, wherein the approximate predetermined driving time is based on a driving path of the automobile at the driving speed sensed by the automobile speed sensing sensor; and
a steering wheel angle sensing sensor configured to sense a steering wheel angle of a steering wheel,wherein when the driving path turns left with the curved road, the controller rotates the left headlight to the left at the approximate predetermined driving time prior to when the automobile is projected to enter the curved road,wherein the controller rotates the right headlight in a direction of the steering wheel angle sensed by the steering wheel angle sensing sensor, andwherein the rotation of the right headlight occurs approximately when the automobile enters the curved road, which is approximately the predetermined driving time after the rotation of the left headlight.

6. A method of controlling a head lamp apparatus of an automobile, in which a left headlight disposed at a front-left side of the automobile and a right headlight disposed at a front-right side of the automobile, wherein both the left headlight and the right headlight are configured to direct light in front of the automobile, the method comprising:
-
a first operation of sensing a driving speed of the automobile; a second operation of receiving a driving position of the automobile; and a third operation of rotating one of the left headlight and the right headlight to direct light toward a curved road when the driving position of the automobile received in the second operation is an approximate predetermined driving time prior to the automobile turning with the curved road, wherein the approximate predetermined driving time is based on a driving path of the automobile at the driving speed sensed in the first operation; sensing a steering wheel angle of a steering wheel; and a fourth operation of rotating the right headlight in a direction of the steering wheel angle when the driving path turns left with the curved road, wherein the third operation includes rotating the left headlight to the left when the driving path turns left with the curved road at the approximate predetermined driving time prior to when the automobile is projected to enter the curved road, and wherein the rotating of the right headlight occurs approximately when the automobile enters the curved road, which is approximately the predetermined driving time after the rotation of the left headlight. - View Dependent Claims (7, 8, 9, 10, 13, 14)
