Variable Headlamp Beam Pattern - Lighting Requirements for Different Driving Situations

Light distributions of headlamps are defined as static values. Neither FMVSS nor ECE allow variable beam pattern for low beam headlamps. New electronic systems and sensors available for car applications facilitate a situative. lighting that prepares an optimum lighting for each driving Situatuion.

This paper shows the necessity of different beam patterns for certain driving situations. Based on an road geometry analysis and an investigation of objects in the street the optimum ligh! dictrihutionr are carried out for the single situations.
