Method and device for controlling at least one headlight of a vehicle
First Claim
1. A method for controlling at least one headlight of a vehicle, the method comprising the steps of:
- reading in a first brightness signal, the first brightness signal representing a first brightness, which is assigned to a first emission characteristic of the at least one headlight for illuminating the surroundings of the vehicle, of the surroundings of the vehicle;
receiving a second brightness signal, the second brightness signal representing a second brightness, which is assigned to a second emission characteristic of the at least one headlight for illuminating the surroundings of the vehicle, of the surroundings of the vehicle;
ascertaining a brightness deviation between the first and the second brightnesses by using the first brightness signal and the second brightness signal; and
setting a debouncing time for changing from the first emission characteristic to the second emission characteristic as a function of the brightness deviation.

Abstract
A method for controlling at least one headlight of a vehicle, in which the at least one headlight has first and second emission characteristics for illuminating the surroundings of the vehicle. The reading in of a first brightness signal initially occurs. In this case, the first brightness signal represents a first brightness, which is assigned to the first emission characteristic, of the surroundings of the vehicle. Subsequently, the receiving of a second brightness signal occurs. The second brightness signal represents a second brightness, which is assigned to the second emission characteristic, of the surroundings of the vehicle. In a further task, a brightness deviation is ascertained between the first and the second brightnesses by using the first and the second brightness signals. Finally, the setting of a debouncing time occurs for changing from the first emission characteristic to the second emission characteristic as a function of the brightness deviation.
