  • determining a traffic sign within the detected image;

    determining an alignment of the determined traffic sign with respect to the motor vehicle, wherein the alignment indicates an angle formed between a straight line parallel to a longitudinal direction of the motor vehicle and a plane parallel to the traffic sign, andtriggering a signal device of the assistance system as a function of the alignment, wherein the signal device is triggered if the alignment of the traffic sign with respect to the motor vehicle is within a determined angular range;

    wherein alignment of the determined traffic sign is determined by dividing an image of a traffic sign within a detected image, into a number of areas and, assigning a particular value to each area depending on at least one of;

    a brightness and a color of an area,wherein a gradient line extends between two of said areas that differ from each other by a determined value and that are above a predetermined threshold, the gradient line representing an edge and thus an angle of the traffic sign relative to the straight line parallel to the longitudinal direction of the motor vehicle.
