The present invention provides a leveling apparatus for a vehicle headlamp, which has a tilting sensor capable of scanning the road surface and a light source module for emitting light, which are integral with each other, thereby simply controlling adjustment of a light emitting position and increasing the accuracy and reliability of changes in the light emitting position. In other words, the leveling apparatus allows the angles of the tilting sensor and the light source module to be adjusted together by a motor, thereby simplifying leveling conditions as the relationship between an optical module and the road surface. In addition, the leveling apparatus can provide feedback on the road surface as the sensing direction of the tilting sensor matches the road surface when performing aiming of the light source module by operation of the motor, thereby identifying the road surface without a separate structure and determining a failure when continuous sensing errors are detected. In addition, the leveling apparatus can perform only control so that an actuator is operated until sensing of the tilting sensor reaches a normal range when performing aiming of the light source module, thereby simplifying the control, and allows a rotating device constituting the actuator to use a friction method or a driving method using a belt to minimize mechanical noise, thereby reducing discomfort caused by the noise.

    본 발명에서는 노면 스캔이 가능한 틸팅센서와 빛을 조사하는 광원모듈이 통합됨으로써, 빛 조사 위치의 조정을 위한 제어가 단순화되고, 빛 조사 위치 변화의 정확도 및 신뢰도가 향상된다. 즉, 틸팅센서와 광원모듈이 모터에 의해 함께 각도가 조절됨에 따라 레벨링 조건을 광학모듈과 노면 관계로 단순화된다. 또한, 모터의 동작에 의해 광원모듈의 에이밍 수행시, 틸팅센서의 센싱방향과 노면이 일치됨에 따라 노면에 대한 피드백이 수행됨으로써, 별도 구조없이 노면 파악과 더불어 지속적인 센싱오류 감지시 고장 판단이 가능하다. 또한, 본 발명에 따른 액추에이터는 광원모듈의 에이밍 수행시 틸팅센서의 센싱이 정상범위에 도달할 때까지 동작되는 제어만 수행되어 제어가 단순화되고, 액추에이터를 이루는 회전기구가 마찰 방식 또는 벨트에 의한 구동 방식을 가짐에 따라 기구적 소음이 최소화되어 소음 발생에 의한 불쾌감이 저감되는 차량용 헤드램프의 레벨링 장치가 소개된다.
