Collaborative vehicle headlight directing
Various embodiments include methods and vehicles, such as an autonomous vehicle, a semi-autonomous vehicle, etc., for collaboratively directing or configuring one or more headlights of a vehicle to avoid visually interfering with operation of an oncoming vehicle. Various embodiments may include receiving, by a first vehicle processor, a first collaborative lighting message from a second vehicle, wherein the first collaborative lighting message requests that the first vehicle direct one or more headlights of the first vehicle to avoid visual interference with operation of the second vehicle and directing one or more the headlights of the first vehicle in accordance with the collaborative lighting plan. Directing the headlights to avoid visual interference with operation of the second vehicle may include switching the headlights to a low-beam configuration.

receiving, by a processor of a first vehicle, a first collaborative lighting message from a second vehicle, wherein the first collaborative lighting message requests that the first vehicle direct one or more headlights of the first vehicle to avoid visual interference with operation of the second vehicle; and
directing, by the first vehicle processor, one or more headlights of the first vehicle in accordance with the first collaborative lighting message prior to the first vehicle reaching an interference point beyond which headlights of the first vehicle might visually interfere with the operation of the second vehicle.
2. The method of claim 1 , wherein directing one or more headlights of the first vehicle in accordance with the first collaborative lighting message comprises switching the headlights of the first vehicle from a high-beam configuration to a low-beam configuration.
3. The method of claim 1 , wherein directing one or more headlights of the first vehicle in accordance with the first collaborative lighting message comprises at least one of lowering a projection angle, decreasing a width, pointing one or more headlights away from the second vehicle, or decreasing a brightness of the one or more headlights of the first vehicle.
4. The method of claim 1 , wherein directing one or more headlights of the first vehicle in accordance with the first collaborative lighting message comprises initiating a gradual change in a configuration of the one or more headlights of the first vehicle before the one or more headlights of the first vehicle visually interfere with the operation of the second vehicle.
5. The method of claim 1 , wherein the first collaborative lighting message identifies at least one of a velocity or position of the second vehicle relative to the first vehicle.
6. The method of claim 1 , further comprising:
determining whether an obstruction or roadway feature causes the interference point to be closer to the second vehicle than the interference point would be absent the obstruction or roadway feature.
7. The method of claim 6 , further comprising:
receiving, by the first vehicle processor, headlight interference information including details regarding the obstruction or roadway feature.
8. The method of claim 1 , further comprising:
determining whether the one or more headlights of the first vehicle no longer interfere with visual operation of the second vehicle; and
directing one or more headlights of the first vehicle to return to a previous configuration in response to determining that the one or more headlights of the first vehicle will no longer interfere with the visual operation of the second vehicle.
9. The method of claim 8 , wherein directing one or more headlights of the first vehicle to return to the previous configuration in response to determining that the one or more headlights of the first vehicle will no longer interfere with the visual operation of the second vehicle comprises automatically switching the one or more headlights to a high-beam configuration after passing the second vehicle.

12. The first vehicle of claim 10 , wherein the processor is further configured with processor-executable instructions to direct one or more headlights of the first vehicle in accordance with the first collaborative lighting message by at least one of lowering a projection angle, decreasing a width, pointing one or more headlights away from the second vehicle, or decreasing a brightness of the one or more headlights of the first vehicle.
13. The first vehicle of claim 10 , wherein the processor is further configured with processor-executable instructions to direct one or more headlights of the first vehicle in accordance with the first collaborative lighting message by initiating a gradual change in a configuration of the one or more headlights of the first vehicle before the one or more headlights of the first vehicle visually interfere with the operation of the second vehicle.
14. The first vehicle of claim 10 , wherein the processor is further configured with processor-executable instructions such that the first collaborative lighting message identifies at least one of a velocity or position of the second vehicle relative to the first vehicle.
15. The first vehicle of claim 10 , wherein the processor is further configured with processor-executable instructions to:
determine whether an obstruction or roadway feature causes the interference point to be closer to the second vehicle than the interference point would be absent the obstruction or roadway feature.
16. The first vehicle of claim 15 , wherein the processor is further configured with processor-executable instructions to:
receive headlight interference information including details regarding the obstruction or roadway feature.
17. The first vehicle of claim 10 , wherein the processor is further configured with processor-executable instructions to:
determine whether the one or more headlights of the first vehicle no longer interfere with visual operation of the second vehicle; and
