A computer readable medium having a computer program, which is executable by a processor, comprising:
- a program code arrangement having program code for determining a lane-adaptation parameter for a lane-keeping system of a vehicle having at least one surround sensor, by performing the following:
- reading in, from a sensor signal from the at least one surround sensor, an obstacle-extension area of a visibility obstacle, caused by at least one vehicle driving in front, transversely to a course of a traffic lane in which the vehicle is to travel;
- and
- determining the lane-adaptation parameter as a function of the read-in obstacle-extension area and a vehicle-extension area transversely to the course of the traffic lane in which the vehicle is to travel, the lane-adaptation parameter being determined so that the lane-keeping system when using the lane-adaptation parameter is set up to reduce an overlap of the obstacle-extension area and the vehicle-extension area.
