SYSTEM FOR DETECTING FOG DIRECTLY IN FRONT OF A MOTOR VEHICLE

The invention relates to a method for detecting fog (52) in a predetermined vicinity (32) in front of a motor vehicle (10), wherein a light beam (44) is emitted into the vicinity (32) by a light source (18) of the motor vehicle (10) and, during this, a camera image (B) at least of the vicinity (32)...

Beschreibung
Zusammenfassung:	The invention relates to a method for detecting fog (52) in a predetermined vicinity (32) in front of a motor vehicle (10), wherein a light beam (44) is emitted into the vicinity (32) by a light source (18) of the motor vehicle (10) and, during this, a camera image (B) at least of the vicinity (32) is generated by a camera (28) of the motor vehicle (10) and a spatial brightness distribution (54, 58) is determined in the camera image (B) by an analysis device (46) and the presence of fog (52) is signalled by means of a fog signal (F) if the brightness distribution (54, 58) satisfies a predetermined distribution criterion.
