Abstract

A method for controlling a light emission of at least one headlight of a, includes determining structure information which represents the presence of a structure which at least partially encloses a roadway traveled by the vehicle. The method also includes generating a control signal for controlling the light emission, using the structure information.

Claims

1. A method for controlling a light emission of at least one headlight of a vehicle, the method comprising:

determining structure information which represents the presence of a structure which at least partially encloses a roadway traveled by the vehicle; and

generating a control signal for controlling the light emission, using the structure information.

2. The method of claim 1, further comprising:

reading in image data of the surroundings of the vehicle from an interface with a surroundings recognition device of the vehicle, the structure information being determined in the determining, using the image data.

3. The method of claim 1, wherein at least one dimension of the roadway and/or of the structure is determined in the determining, the control signal being generated in the generating, using the at least one dimension.

4. The method of claim 1, wherein a relative position of the vehicle with respect to the roadway and/or with respect to the structure is determined in the determining, the control signal being generated in the generating, using the relative position.

5. The method of claim 1, wherein at least one partial section of a wall of the structure is determined in the determining, and the control signal is generated in the generating so that the at least one partial section of the wall of the structure is excluded from the light emission of the at least one headlight.

6. The method of claim 1, further comprising:

providing the control signal to an interface with a light control device of the vehicle, the control signal being usable by the light control device to adjust the light emission of the at least one headlight.

7. A device for controlling a light emission of at least one headlight of a vehicle, comprising:

a determination device to determine structure information which represents the presence of a structure which at least partially encloses a roadway traveled by the vehicle; and

a generation device to generate a control signal for controlling the light emission, using the structure information.

8. A computer readable medium having a computer program, which is executable by a processor, comprising:

a program code arrangement having program code for controlling a light emission of at least one headlight of a vehicle, by performing the following;

determining structure information which represents the presence of a structure which at least partially encloses a roadway traveled by the vehicle; and

generating a control signal for controlling the light emission, using the structure information.

9. The computer readable medium of claim 8, further comprising:

reading in image data of the surroundings of the vehicle from an interface with a surroundings recognition device of the vehicle, the structure information being determined in the determining, using the image data.
