Abstract

A method is provided for controlling a headlamp of a motor vehicle. An object is detected by an object detecting device of the motor vehicle. An angle is determined between a geometrical longitudinal axis of the motor vehicle passing through the object detecting device and a geometrical connecting line between the object detecting device and the object. A glare reduction range of the headlamp is determined using the angle without taking into account a total distance between the object and the motor vehicle, the headlamp illuminating the glare reduction range with a lower brightness than areas adjacent to the glare reduction range.
