Method for operating a light-based driver assistance system of a motor vehicle

A method to operate a light-based driver assistance system of a motor vehicle, wherein at least one headlight of the motor vehicle projects a light distribution onto a roadway in front of the motor vehicle, the light distribution produces a lane marking, a width of which is essentially equal to a vehicle width of the motor vehicle and a course of which corresponds to a predicted lane course when the motor vehicle is driving, the method comprising:

• predicting a lane course of the motor vehicle when driving through a curve;
• determining a point of intersection of an inner lane boundary of the predicted lane course with an inner light field limitation of a light field projectable onto the roadway via the headlight when driving through the curve;
• setting a distal boundary of the lane marking, the distal boundary being a section of a straight line, wherein the straight line passes through the point of intersection and a center of the curve;
• and
• projecting a light distribution onto the roadway in front of the motor vehicle to create the lane marking that terminates at the distal boundary.
