发明名称 AUTOMOTIVE HEADLAMP APPARATUS FOR CONTROLLING LIGHT DISTRIBUTION PATTERN
摘要 An automotive headlamp apparatus includes headlamp units placed in a vehicle and a control unit which controls the illumination of the headlamp units. The headlamp units form a lower beam distribution pattern and an upper beam distribution pattern, and is configured so that a partial region of the upper beam distribution pattern can be non-illuminated. When the entirety of vehicle existent area of a vehicle-in-front travelling in front of a driver's vehicle is contained within the partial region, the control unit controls the headlamp units in such a manner that the partial region is non-illuminated; when at least a part of the vehicle existent area is contained within a region of the upper beam distribution pattern which is other than the partial region, the control unit controls the headlamp units in such a manner that the upper beam distribution pattern is not formed.
