Abstract

A method for setting a pivot angle of a headlamp with an asymmetrical low beam when a vehicle is negotiating a bend, wherein a course of a highway line is determined, a contact point is determined, wherein a tangent from the headlamp to the contact point makes contact with the highway line, and the headlamp is adjusted such that a projection of an intersection of a horizontal portion of a cut-off line of the headlamp and an ascending branch of the cut-off line of the headlamp in a plane in front of the vehicle and perpendicular to the longitudinal axis of the vehicle on the highway falls within a circle of predetermined radius around the contact point.
