Abstract
A method for the automatic light control for a motor vehicle with a camera sensor for monitoring the environment in front of the motor vehicle is presented. With the camera sensor, an image sequence of the motor vehicle environment in front of the motor vehicle is recorded. The lane of the own motor vehicle is estimated from the image data. At least one evaluation window along the lane is set in the image, so that preceding and oncoming motor vehicles are recorded. Points of light in the image sequence are pursued (tracked). On the basis of the image data, the lights of other motor vehicles are detected, and the front headlights are controlled in such a manner that the drivers of other motor vehicles are not blinded.
