First Claim
Patent Images
1. A head lamp apparatus of an automobile, comprising:
- a left dynamic bend light (DBL) disposed at a front-left side of the automobile to light in a front direction;
a right DBL disposed at a front-right side of the automobile to light in a front direction;
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; and
a controller configured to rotate one of the left DBL and the right DBL to the left or right so as to light a curved road when the driving position of the automobile received by the GPS receiving unit is a position from which the automobile arrives at the curved road on a driving path of the automobile at the driving speed sensed by the automobile speed sensing sensor within a reference time.
