Abstract
A leveling apparatus for a vehicle headlamp includes: a housing disposed at a front side of a vehicle; a light source module disposed in the housing to emit light; a tilting sensor disposed in the housing to detect an inclination degree of a road; a tilting means to tilt the light source module and the tilting sensor together; and a controller. The controller receives a signal detected by the tilting sensor and controls the tilting means based on the inclination degree of the road to adjust a light emission angle of the light source module. In addition, the tilting sensor operates until a sensed output of the tilting sensor reaches a normal range.
Claims15
A leveling apparatus for a headlamp for a vehicle, the leveling apparatus comprising:
- a housing disposed at a front side of a vehicle;
- a light source module disposed in the housing and configured to emit light;
- a tilting sensor disposed in the housing and configured to detect an inclination degree of a road;
- a tilting means configured to tilt the light source module and the tilting sensor together;
- and
- a controller configured to:
- receive a signal detected by the tilting sensor and control the tilting means based on the inclination degree of the road to adjust a light emission angle of the light source module,
- wherein when a change in angle detected by the tilting sensor is equal to or larger than a reference angle, the controller is configured to recognize whether an amount of the change in angle increases or decreases and allow the tilting means to tilt based on the amount of change in angle.
A leveling apparatus for a headlamp for a vehicle, the leveling apparatus comprising:
- a housing disposed at a front side of a vehicle;
- a light source module disposed in the housing and configured to emit light;
