ABSTRACT:
A device for automatically correcting the elevation angle of at least one vehicle headlight during changes in the attitude of said vehicle, the device being of the type comprising at least two lighting sensors integrated in the headlight and constrained to move therewith, the two sensors being disposed to detect the brightness of the road in the field of illumination of the headlight in two different directions at two predetermined angles relative to a reference direction of said headlight, an actuator suitable for varying the angle of inclination of the headlight relative to the vehicle, and processor means suitable for generating an actuator control signal as a function of the signals delivered by the sensors which are essentially proportional to the quantity of light that each of them receives. According to the invention, the processor means comprise gain servo-control means controlled by the signal provided by the first sensor, said gain servo-control means controlling the gain of a variable gain circuit receiving the signal from the second sensor, in such a manner that said gain increases with decreasing signal from the second sensor.
