A system and method of automatically controlling exterior vehicle lights includes
an image sensor and a controller to generate control signals. The control signals
are derived based on information obtained from the image sensor as well as other
detected parameters pertaining to the detected light source(s), the vehicle having
the inventive control system, and the ambient environment. The control circuit
may simply turn certain exterior lights on or off, or change the brightness, aim,
focus, etc. to produce various beam patterns that maximize the illuminated area
in front of the vehicle without causing excessive glare in the eyes of other drivers.
