Abstract

A method for adapting an upper headlight beam boundary of a light cone of at least one headlight of a vehicle. The method includes detecting a time curve of a pitch rate of the vehicle or a value that is dependent on the pitch rate and/or of a roll rate of the vehicle or a value that is dependent on the roll rate. The method also includes ascertaining an envelope curve and/or an amplitude of the time curve and/or an average value of the time curve. The method also includes providing a control signal for adapting the upper headlight beam boundary of the headlight beam.
