Control system to automatically control vehicle headlamps
First Claim
Patent Images
1. An automatic vehicle exterior light control, comprising:
- an image array sensor configured to capture at least one frame;
a controller configured to identify at least one AC powered light source;
said controller is further configured to distinguish between external sources of light and reflections from the controlled vehicle'"'"'s head lamps off of various external objects, wherein said controller is further configured to generate either an exterior light control, an undim counter control, a dim counter control, a sub-combination or combination thereof.

Abstract
An automatic vehicle headlamp dimming system which includes an optical system and an imaging processing system. The optical system is configured to discriminate between headlamps and tail lamps, and focus the light rays from the headlamps and tail lamps on different portions of a pixel sensor array. The optical system as well as the image processing system provides for relatively increased discrimination of headlamps and tail lamps of other vehicles and also enables the high beam headlamps of the control vehicle to be controlled as a function of the distance as well as horizontal angular position of other vehicles relative to the controlled vehicle.

30. An automatic vehicle exterior light control, comprising:
a controller configured to distinguish between external sources of light and reflections from the controlled vehicle'"'"'s head lamps off of various external objects by comparing the relative brightness of imaged objects between two consecutive images where the brightness of at least one of said head lamps is varied between each image, wherein said controller is further configured to generate either an exterior light control, an undim counter control, a dim counter control, a sub-combination or combination thereof. - View Dependent Claims (31, 32, 33)
