Control system to automatically control vehicle headlamps
First Claim
1. A control system for automatically controlling the state of the head lamps of a controlled vehicle, the control system comprising:
- an optical system for imaging external sources of light within a predetermined field of view, the optical system including an image array sensor and two or more lenses configured to image said predetermined field of view onto two or more corresponding portions of said array; and
an image processing system for processing images from said optical system and providing a control signal for controlling the head lamps as a function of the relative output of the pixels imaging said external sources of light.

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.
