A vehicle lamp tool providing a controller which calculates the luminance distribution of light distribution pattern, an optical device which generates light distribution pattern in an illuminatable area D and a first driving circuit which drives the optical device. The controller transmits a first light distribution correction signal for correcting the inclination of a current light distribution pattern to the first driving circuit if the inclination angle of a vehicle with respect to vertical direction indicated by a detection signal received from a vehicle height sensor is equal to or less than a threshold value. The first driving circuit transmits a first correction driving signal based on the first light distribution correction signal to the optical device. The optical device drives an LD and a light deflector to correct the current light distribution pattern.

SYSTEM AND METHOD OF CONTROLLING A VEHICULAR HEADLAMP FOR PREVENTING A SHADOW AREA

A system and method control a vehicular headlamp for preventing a shadow area between a low beam and a high beam of a headlamp using a camera unit. The method includes periodically determining whether a high beam of the vehicular headlamp is lit or illuminated. Upon determining that the high beam is illuminated, the method includes determining whether a darkness cell is formed in front image data of the vehicle, which is transmitted from a camera unit. Upon determining that the darkness cell is formed, the method includes changing a leveling motor to be directed upward by 1 step and storing a changed number of steps. Upon determining that the darkness cell is not formed, the method includes driving the leveling motor by the pre-stored number of steps.
