Abstract

Disclosed is a system that helps to reduce the danger caused by drivers that forget to turn off their high beams while at the same time provides a level of lighting that allows the driver to have improved visibility while also not impairing other drivers.

Automatic High Beams

When driving on roads where the visibility is low, the driver often needs to turn on their high beam to improve visibility. When the driver is approaching other vehicles either from behind or vehicles that are coming in the opposite direction, they have to keep remembering to turn off or lower their high beam. There are times when drivers forget to lower their high beams, thus causing a traffic hazard. Also, while lowering the high beam may alleviate the inconvenience to the other drivers and also reduce the risk of temporarily blinding them, it creates a situation where the driver may not have good visibility on the side of the road that is opposite to the other drivers. This then creates a hazard for the driver who had to turn off the high beam.

The novel contribution is a system with vehicle light fixtures that are made of individual light cells that can be independently adjusted (moved, dimmed, etc.) such that the lights do not adversely affect the other drivers, while still maintaining good visibility for the driver who is operating the vehicle in which the system is implemented.

The system uses processors for:


- Detecting an approaching vehicle
- Calculating the distance to the approaching vehicle, the approaching direction
- Gradually lowering the intensity of the light cells such that the section of the light that provides the most direct hit to the other vehicle is not as bright as the other sections of that same light that does not have a direct hit on the other vehicle
- Adjusting the angle of the cone of vision of the light cells. Partial adjustments may be made to the cone of vision such that the light from the cells that would adversely affect the other drivers are dimmed or turned off whereas the other light cells retain their intensity, depending on the current traffic situation. If incoming traffic is ahead, bright lights or high beams will be redirected accordingly, i.e. the an...
