Method for controlling adaptive motor vehicle headlight

A method for controlling an adaptive motor vehicle headlight (2), wherein a first data storage device (3) is assigned to the adaptive motor vehicle headlight (2), wherein the adaptive motor vehicle headlight (2) is designed to emit different segmented light distributions having a resolution of at least 2×12 and has light sources (2aa) arranged in segments (2a) for this purpose, wherein each segment (2aa) comprises at least one LED light source, the method comprising:

• a) providing the adaptive motor vehicle headlight (2) and the first data storage device (3) as well as storing a number of data sets (3a1, 3a2, 3a3, 3a4, 3b1, 3b2, 3b3, 3b4) on the first data storage device (3), wherein each data set specifies a light intensity value (IsegmLV) for each segment (2a) for implementing light distribution (LVa1, LVa2, LVa3, LVa4, LVb1, LVb2, Lvb3) to be emitted by the adaptive motor vehicle headlight (2), wherein the number of data sets comprises at least two groups (3a, 3b) of data sets, namely a first group (3a) of dipped beam data sets (3a1, 3a2, 3a3, 3a4) and a second group (3b) of full beam data sets (3b1, 3b2, 3b3, 3b4), wherein each group (3a, 3b) comprises at least one data set (3a1, 3a2, 3a3, 3a, 3b1, 3b2, 3b3, 3b4), wherein each dipped beam data set (3a1, 3a2, 3a3, 3a4) is configured to produce dipped beam distribution and each full beam data set (3b1, 3b2, 3b3) is configured to produce full beam distribution, wherein the configurations of the respective light distributions are different for different data sets (3a1, 3a2, 3a3, 3a4, 3b1, 3b2, 3b3, 3b+);
• b) connecting the adaptive motor vehicle headlight (2) to a motor vehicle (1), wherein the motor vehicle (1) is designed to output control data (1a) for controlling the adaptive motor vehicle headlight (2);
• c) transmission of the control data (1a) by the motor vehicle (1) to the adaptive motor vehicle headlight (2), wherein the adaptive motor vehicle headlight (2) has an internal computing unit (2c), which receives the control data (1a) and selects and retrieves data sets (3a1, 3a2, 3a3, 3a4, 3b1, 3b2, 3b3) stored in the first data storage device (3) as a function of the control data (1a), hereinafter also referred to as active data sets;
• and
• d) control of the light sources (2aa) arranged in the segments (2a) by the computing unit (2c) in accordance with the active data sets (3a1, 3a2, 3a3, 3a4, 3b1, 3b2, 3b3) according to step (c) using a configurable smoothing function (Fg), wherein the adaptive motor vehicle headlight (2) has an internal data storage device (2d), on which a light distribution transition control algorithm (LV-AL) is stored, wherein the light distribution transition control algorithm (LV-AL) can be specified by an interface (4), by means of which the internal data storage device (2d) can be externally accessed, and the configurable smoothing function (Fg) is set by the light distribution transition control algorithm (LV-AL), wherein the configurable smoothing function (Fg) is used in any case in compliance with the following rules:
• d1) determining the number of active data sets (3a1, 3a2, 3a3, 3a4, 3b1, 3b2, 3b3), wherein the control data (1a) is used to give each active data set (3a1, 3a2, 3a3, 3a4, 3b1, 3b2, 3b3) an individual percentage weighting (wab1, wab2, wab3, wfern1, wfern2, wfern3),
• d2) determining the target light intensities (IsegmZ) to be output of each segment (2a) by superimposing the light intensity values (IsegmLV) that can be derived from the active data sets (3a1, 3a2, 3a3, 3b1, 3b2, 3b3) taking the respective weighting into account,
• d3) output of the target light intensities (IsegmZ) for each segment (2a) taking into account a permissible maximum temporal rate of change of the light intensity that can be predetermined, which is emitted by the respective segment (2a), wherein if a permissible maximum temporal rate of change (Var) that can be predetermined by the configurable smoothing function (Fg) is exceeded, the target light intensities (IsegmZ, IsegmZ′) are temporarily manipulated such that the permissible maximum temporal rate of change (Var_max) is not exceeded.
