Abstract

A method for controlling a matrix beam headlamp (M) with adaptive light functions in which using non-glare lighting and/or targeted lighting of objects (O) with segments (S 1 -Sn) of the light distribution of the matrix beam headlamp (M). Different switch-on and switch-off boundaries are defined for the individual segments (S 1 -Sn).

Claims (19)

1. A method for controlling a matrix beam headlamp with adaptive light functions, comprising the step:

using at least one of non-glare lighting and targeted lighting of objects with segments of the light distribution of the matrix beam headlamp, wherein each segment has switch-off boundaries that are different from its switch-on boundaries, and wherein said switch-off boundaries are defined within said switch-on boundaries for the individual segments.

2. The method according to claim 1 , wherein

the switch-off boundaries of the individual segments are defined by the boundaries of the individual segments, wherein the boundaries are segment boundaries.

3. The method according to claim 1 , wherein the switch-on boundaries of the individual segments are defined by additional boundaries, wherein the additional boundaries are hysteresis boundaries.

4. The method according to claim 1 , wherein the distance between the segment boundaries and the additional boundaries defines hystereses.

5. The method according to claim 1 , wherein

the segment is deactivated as soon as an object passes the boundary and is located within the lighting area of the segment and

the segment is activated as soon as the object passes the additional boundary and has definitely left the lighting area of the segment.

6. The method according to claim 1 wherein

the segment is activated as soon as an object passes the boundary and is located within the lighting area of the segment and

the segment is deactivated as soon as the object passes the additional boundary and has definitely left the lighting area of the segment.

7. The method according to claim 5 , wherein

a continuous transition of the light power of the matrix beam headlamp takes place between different segments.

8. The method according to claim 7 , wherein

the transition is described by a transition function.

9. The method according to claim 8 , wherein

the transition function can be configured in at least one of form and time.

10. A matrix beam headlamp for use in the method with of claim 1 .
