Abstract

A method for controlling an adaptive motor vehicle headlight (AMVH), wherein a first data storage device (DSD) is assigned to the AMVH, which is designed to emit different segmented light distributions having a resolution of at least 2×12 and has light sources arranged in segments for this purpose, each segment including at least one LED light source. The method includes: a) providing the AMVH and the first DSD and storing a number of data sets on the first DSD, b) connecting the AMVH to a motor vehicle, which is designed to output control data for controlling the AMVH, c) transmitting the control data by the motor vehicle to the AMVH, wherein the AMVH has an internal computing unit, which receives the control data and selects and retrieves data sets stored in the first DSD as a function of the control data (“active data sets”), d) controlling the light sources arranged in the segments by the computing unit in accordance with the active data sets, d1) determining the number of active data sets, wherein the control data is used to give each active data set an individual percentage weighting, d2) determining target light intensities to be output of each segment by superimposing the l…
