NUMERICAL METHODS FOR THE COMPUTATION OF ANALYTIC SINGULAR VALUE DECOMPOSITIONS

The corrector device comprises at least one illumination sensor (10, a, b, c) integrated in a headlamp and fixed to move with the headlamp reflector (12), the sensor-reflector assembly normally pointing in such a direction as to detect the luminance of the road in at least one angular direction at a predetermined angle (o+ phi + theta ) with the horizontal (OY), with processing means being provided that are suitable for generating a corrector signal which is a function of the luminance of the road in said direction, whenever the trim of the vehicle changes, the device further including at least one actuator controlled by said corrector signal in order correct the direction in which the reflector-sensor assembly is pointing.
