1. A method for estimating a roadway course in a roadway section ahead of a vehicle as the vehicle is moving in the direction of travel, the method comprising:
- recognizing, by a computer processor, at least one reflective or self-luminous object in an image of the roadway section;
ascertaining, by a computer processor, a change over time of a position of the at least one object based on the image of the roadway section, the ascertaining including evaluating a trace of a movement of the at least one object in the image taken by a camera according to a long-term exposure; and
estimating, by a computer processor, the roadway course using the ascertained position of the at least one object.

7. A method for controlling a light emission of at least one headlight of a vehicle as the vehicle moves along the direction of travel, the method comprising:
-
estimating, by a computer processor, a roadway course in a roadway section ahead of the vehicle in the direction of travel by performing the following; recognizing, by a computer processor, at least one reflective or self-luminous object in an image of the roadway section; ascertaining, by a computer processor, a change over time of a position of the at least one object based on the image of the roadway section, the ascertaining including evaluating a trace of a movement of the at least one object in the image taken by a camera according to a long-term exposure; and estimating, by a computer processor, the roadway course using the ascertained position of the at least one object; and generating, by a computer processor, an actuating signal for controlling the light emission of the at least one headlight, using the estimated roadway course.
