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
First Claim
1. A method for providing automated lane guidance using a lane-keeping system of a vehicle having at least one surround sensor, the method comprising:
- reading in by the lane-keeping system, 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;
determining, by the lane-keeping system, a 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; and
providing, by the lane-keeping system, automated lane guidance of the vehicle using the lane-adaptation parameter to reduce an overlap of the obstacle-extension area and the vehicle-extension area.

Abstract
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.

5. A method for providing automated lane guidance of a vehicle, the method comprising:
-
determining, by the lane-keeping system, a lane-adaptation parameter for a lane-keeping system of a vehicle having at least one surround sensor, by performing the following; reading in by the lane-keeping system, 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, by the lane-keeping system, 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; and performing, by the lane-keeping system, the automated lane guidance using the lane-adaptation parameter, so that the overlap of the obstacle-extension area and the vehicle-extension area is reduced. - View Dependent Claims (6, 7)
