Abstract
Provided is an apparatus and method for providing a fail-safe in a head lamp apparatus. In one aspect of the present invention, an apparatus for providing a fail-safe in a head lamp apparatus includes an apparatus for providing a fail-safe in a head lamp apparatus includes an optical module generating a plurality of beam patterns using a predetermined shield, a shield driving unit driving the shield in the optical module, a module driving unit controlling an irradiation angle of the optical module in leftward and rightward directions, a leveling driving unit controlling the irradiation angle of the optical module in upward and downward directions, and a controller controlling the shield driving unit, the module driving unit, and the leveling driving unit, wherein when a fail occurs to one of the shield driving unit, the module driving unit, and the leveling driving unit, the controller controls at least one driving unit which is normally operating to adjust the beam pattern or the beam irradiation angle of the optical module.
