Abstract
A lamp device includes: an optical unit that is provided in a vehicle and irradiates light; a leveling unit configured to adjust an optical axis of the optical unit in a vertical direction; an object detection unit configured to detect an object around the vehicle to generate surrounding environment information; a driving condition determination unit configured to determine a driving condition of the vehicle; and a control unit configured to control the leveling unit, in which the control unit determines a projection surface of the optical unit based on the surrounding environment information and the driving condition and controls a projection distance of light by the leveling unit.
Claims18
A lamp device, comprising:
- an optical unit to be provided in a vehicle and configured to irradiate light;
- a leveling unit configured to adjust an optical axis of the optical unit in a vertical direction to adjust a projection distance of the light;
- an object detection unit configured to detect an object around the vehicle to generate surrounding environment information;
- a driving condition determination unit configured to determine a driving condition of the vehicle;
- and
- a control unit configured to control the leveling unit,
- wherein the control unit is configured to determine a projection surface of the optical unit based on the surrounding environment information and the driving condition and determine a projection distance of the optical unit by controlling the leveling unit;
- wherein the control unit is configured to sets the projection surface of the lamp based on whether the vehicle is driving and the type of the object, and set the projection distance based on a distance between the object and the vehicle.
A method of controlling a lamp, comprising:
- collecting driving information of a vehicle;
- collecting surrounding environment information on an object around the vehicle;
- and
- setting a projection surface and a projection distance of the lamp of the vehicle based on the driving information and the surrounding environment information, wherein the setting includes:
- determining whether the vehicle is driving;
- selecting a target that is a criterion for recognizing light of the lamp based on whether there is the object and the type of the object;
- and
- setting the projection surface of the lamp based on whether the vehicle is driving and the type of the object, and setting the projection distance based on a distance between the object and the vehicle.
