Abstract
Provided is a lamp system with improved visibility, and more particularly, to a lamp system positioned on a vehicle, the system including: a first lamp module generating a low beam, and outputting the low beam to the outside of the vehicle; a second lamp module generating light of a predetermined symbol, and outputting light to the outside of the vehicle; a sensor unit including at least one of an advanced driver assistance system (ADAS) sensor or an illumination sensor, and outputting external situation information; and a control unit receiving the output of the sensor unit, and controlling brightness of the second lamp module.
Claims11
A lamp system for a vehicle, the system comprising:
- a first lamp module generating light, and outputting light to an outside of the vehicle in one direction;
- a second lamp module generating light of a predetermined symbol, and outputting light to the outside of the vehicle to project the symbol;
- a sensor unit including at least one of an advanced driver assistance system (ADAS) sensor or an illumination sensor to output external situation information;
- and
- a control unit receiving the output of the sensor unit and controlling brightness of the second lamp module based on output of the sensor unit to promote visbility of the projected symbol;
- wherein the control unit:
- receives surrounding illumination information of the vehicle from the illumination sensor, and
- controls black and white images of the symbol output by the second lamp module to be inverted based on the illumination information exceeding a predetermined reference.
A lamp system for a vehicle, the system comprising:
- a first lamp module generating light, and outputting light to an outside of the vehicle in one direction;
- a second lamp module generating light of a predetermined symbol, and outputting light to the outside of the vehicle to project the symbol;
- a sensor unit including at least one of an advanced driver assistance system (ADAS) sensor or an illumination sensor to output external situation information;
- and
- a control unit receiving the output of the sensor unit and controlling brightness of the second lamp module based on output of the sensor unit to promote visiblity of the projected symbol
- wherein:
- the control unit receives front image information of the vehicle from the ADAS sensor,
- calculates a comparison value for brightness of each pixel based on the image information, and
- controls the brightness of the second lamp module to be increased when the comparison value is reduced by at least a predetermined reference.
A lamp system for a vehicle, the system comprising:
- a first lamp module generating light, and outputting light to the outside of the vehicle in one direction;
- a second lamp module generating light of a predetermined symbol, and outputting light to an outside of the vehicle to project the symbol;
- a sensor unit including at least one of an advanced driver assistance system (ADAS) sensor or an illumination sensor to output external situation information;
- and
- a control unit receiving the output of the sensor unit and controlling brightness of the second lamp module based on output of the sensor unit to promote visiblity of the projected symbol;
- wherein the control unit controls the second lamp module to cause light from the second lamp module to be emitted to a region where light emitted from lamp systems positioned on left and right sides of the vehicle overlap each other when receiving the output of the sensor unit to determine that surrounding illumination of the vehicle is to be increased.
