Abstract
In a method for triggering a driver assistance function of a subject vehicle, image data of surroundings in front of the vehicle is generated by a camera and supplied to an analyzing unit. A driver assistance function is triggered upon detection of a brake light of an other vehicle in the image data. A geometric region of the detected other vehicle is determined as exhibiting the highest pixel brightness values and the color red. The geometric region is detected as a raised brake light of the other vehicle if the geometric region is positioned essentially in the middle of the horizontal structure of the other vehicle, or at least a predetermined height above the roadway, or at least a predetermined distance below a rear window of the other vehicle.
