Abstract
A method for reducing headlight glare from a first vehicle comprising a first headlight and one or more sensors. The method includes illuminating, by the first headlight in a low beam setting, a portion of a road that the first vehicle is traveling along. The one or more sensors may detect a presence of a second vehicle. For example, the one or more sensors may detect the presence of the second vehicle in a region that is receiving direct glare from the first headlight in the low beam setting. The first headlight may dim, in response to the detecting, to a first light output below the low beam setting.
Claims20
A method comprising:
- providing light from a first vehicle comprising:
- a first headlight and one or more sensors;
- illuminating, by the first headlight in a low beam setting, a portion of a road that the first vehicle is traveling along;
- detecting a presence of a second vehicle with the one or more sensors, which the first vehicle is active with the low beam setting;
- and
- dimming, in response to the detecting, the first headlight to a first light output below the low beam setting;
- wherein the first vehicle further comprises a control system configured to control the first headlight, and
- wherein the dimming further comprises controlling the first light output using the control system such that the first light output from the first headlight is changed and the light output from a second headlight of the first vehicle is unchanged.
A method comprising:
- providing light from a first vehicle comprising:
- a first headlight and one or more sensors;
- illuminating, by the first headlight in a low beam setting, a portion of a road that the first vehicle is traveling along;
- detecting a presence of a second vehicle with the one or more sensors, which the first vehicle is active with the low beam setting;
- and
- dimming, in response to the detecting, the first headlight to a first light output below the low beam setting;
- wherein the first vehicle further comprises a control system configured to control the first headlight, and
- wherein the dimming further comprises dimming an entire low beam pattern of the first headlight.
A system of a first vehicle, the system comprising:
- a processing system;
- memory operably connected to the processing system and storing instructions that, when executed, cause the processing system to:
- detect, while the first vehicle is in a low beam setting, a presence of a second vehicle;
- and
- dim, in response to the detecting the presence of the second vehicle, a headlight of the first vehicle to a light output below the low beam setting;
- wherein the dimming of the headlight of the first vehicle further comprises controlling the first light output using the processing system such that the first light output from the first headlight is changed and the light output from a second headlight of the first vehicle is unchanged.
