Method and device for determining a lane-adaptation parameter for a lane-keeping system of a vehicle, as well as method and device for lane guidance of a vehicle

摘要

A method for determining a lane-adaptation parameter for a lane-keeping system of a vehicle having at least one surround sensor. The method includes 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 on which the vehicle is to travel. The method also includes ascertaining 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 is determined so that when using the lane-adaptation parameter, the lane-keeping system is set up to reduce an overlap of the obstacle-extension area and the vehicle-extension area.
