Apparatus for determining reference variables for adjusting the light distribution of a right headlight (S R) and/or a left headlight (S L) of a vehicle driving in a curve. The reference variables can be determined from a first angle relative to the longitudinal axis and/or a second angle relative to the longitudinal axis of the vehicle; the first angle can be determined from the first pieces of information and the second angle can be determined from the second piece of information - With at least one interface for reading in the first pieces of information, namely, from measured values and/or variables to be set by actuators of the vehicle, such as the speed, steering angle, yaw rate, steering lock angle of the front wheels, distance from a vehicle traveling in front of the vehicle in the same direction and/or approaching it, and for reading in the second pieces of information about the course of the road ahead of the vehicle, such as the radius of the curve that is being driven through, the distance away from a prominent point of the road's course such as the starting point, ending point or inflection point of a curve, the beginning, end or section of a road, road extension, highway, downtown road or suburban road, - With a control system for determining the first angle (d) from the first pieces of information and the second angle (p) from the second pieces of information, - The control system can be used to select the one of the angles (d, p) for each of the headlights (S R, S L), - With an interface for connecting the apparatus with actuators for adjusting the light distribution of the headlights (S R, S L) or parts of the headlights (S R, S L), on which reference variable signals can be provided, - With a device for converting the angle (d, p) selected by the control system for the right headlight (S R) and the angle (d, p) selected by the control system for the left headlight (S L) into the reference variable signals, Indicated by The ability to use the control system to limit the second angle (p) to a limited second angle (p L) if an amount (|a|) of a deviation (a=p-d) between the second angle (p) and the first angle (d) is greater than a maximum permitted deviation (a max). - With at least one interface for reading in the first pieces of information, namely, from measured values and/or variables to be set by actuators of the vehicle, such as the speed, steering angle, yaw rate, steering lock angle of the front wheels, distance from a vehicle traveling in front of the vehicle in the same direction and/or approaching it, and for reading in the second pieces of information about the course of the road ahead of the vehicle, such as the radius of the curve that is being driven through, the distance away from a prominent point of the road's course such as the starting point, ending point or inflection point of a curve, the beginning, end or section of a road, road extension, highway, downtown road or suburban road, - With a control system for determining the first angle (d) from the first pieces of information and the second angle (p) from the second pieces of information, - The control system can be used to select the one of the angles (d, p) for each of the headlights (S R, S L), - With an interface for connecting the apparatus with actuators for adjusting the light distribution of the headlights (S R, S L) or parts of the headlights (S R, S L), on which reference variable signals can be provided, - With a device for converting the angle (d, p) selected by the control system for the right headlight (S R) and the angle (d, p) selected by the control system for the left headlight (S L) into the reference variable signals,
