1. A method for adapting a headlight beam boundary of a light cone of at least one headlight of a vehicle, the method comprising:
- detecting, by a sensor, at least a first area of a roadway that is situated ahead of the vehicle in a travel direction of the vehicle;
determining, by processing circuitry, a topography of the first area of the roadway;
determining, by the processing circuitry, a difference between the topography of the first area of the roadway and a topography of a second area of the roadway on which the vehicle is currently situated; and
providing, by the processing circuitry, a headlight control signal based on which the headlight beam boundary is changed prior to the vehicle reaching the first area of the roadway and based on the determined difference in topography between the first and second areas.

9. A system for adapting a headlight beam boundary of a light cone of at least one headlight of a vehicle, comprising:
-
a sensor configured to detect a first area of a roadway that is situated ahead of the vehicle in a travel direction of the vehicle; a control unit including a processor configured to perform the following; determining a topography of the first area of a roadway; determining a difference between the topography of the first area of the roadway and a topography of a second area of the roadway on which the vehicle is currently situated; and providing a headlight control signal based on which the headlight beam boundary is changed prior to the vehicle reaching the first area of the roadway and based on determined difference in topography between the first and second areas.

10. A non-transitory, computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, perform a method for adapting a headlight beam boundary of a light cone of at least one headlight of a vehicle, the method comprising:
-
obtaining from a sensor a signal representing a detected first area of a roadway that is situated ahead of the vehicle in a travel direction of the vehicle; determining a topography of the first area of the roadway; determining a difference between the topography of the first area of the roadway and a topography of a second area of the roadway on which the vehicle is currently situated; and providing a headlight control signal based on which the headlight beam boundary is changed prior to the vehicle reaching the first area of the roadway and based on the determined difference in topography between the first and second areas.
