Abstract

A method for determining a course of a lane of a vehicle. In this connection, a first marking course of a first marking of the lane and a second marking course of a second marking of the lane are initially recorded. The first marking course and the second marking course are subsequently checked for plausibility. Finally, the lane course is determined on the basis of a previous width of the lane and a plausible marking course in response to at least one marking course proving to be implausible in the checking step.

First claim

1 - 11 . (canceled)

12 . A method for determining a course of a lane of a vehicle, comprising:
recording a first marking course of a first marking of the lane and a second marking course of a second marking of the lane; checking the first marking course and the second marking course for plausibility in order to determine a plausible marking course; and determining the lane course based on a previous width of the lane and a plausible marking course in response to at least one marking course proving to be implausible in the checking step.

13 . The method in accordance with claim 12 , wherein the previous lane width is also recorded in the recording step, the previous lane width being a function of a distance between the first lane marking and the second lane marking.

14 . The method as recited in claim 12 , wherein a further marking course of a further marking of a further lane adjoining the lane is recorded in the recording step, the further marking course being checked for plausibility in the checking step, the lane course also being determined based on the further marking course in the determining step in response to the further marking course proving to be plausible in the checking step.

15 . The method as recited in claim 14 , wherein a further lane width of the further lane is also recorded in the recording step, the further lane width being a function of a distance between the further lane marking and one of the first or second markings of the lanes, the lane course also being determined based on the further lane width in the determining step.

16 . The method as recited in claim 12 , wherein a reference position of a further vehicle relative to at least one of the lane and of the vehicle, is also recorded in the recording step, the lane course also being determined on the basis of the reference position in the determining step.

17 . The method as recited in claim 12 , further comprising:
generating a warning signal to alert a driver of the vehicle of an accident risk one of: in response to at least one marking course proving to be implausible in the checking step, or in response to the determining step being executed.

18 . The method as recited in claim 12 , further comprising:
outputting a suggestion signal to recommend a lane change to the driver at least one of: in response to at least one marking course proving to be implausible in the checking step, or in response to the determining step being executed.

19 . The method as recited in claim 12 , further comprising:
reducing a velocity of the vehicle at least one of: in response to at least one marking course proving to be implausible in the checking step, or in response to the determining step being executed.

20 . The method as recited in claim 12 , wherein a surface structure of the lane is also captured in the recording step in order to ascertain a passable area of the lane, the lane course also being determined in the determining step on the basis of the passable area.

21 . A device for determining a course of a lane of a vehicle, the device comprising:
a recording unit to record a first marking course of a first marking of the lane and a second marking course of a second marking of the lane; a plausibility checking unit to check the first marking course of the second marking course for plausibility to determine a plausible marking course; and a unit to determine the lane course based on a previous width of the lane and a plausible marking course in response to at least one marking course proving to be implausible.

22 . A computer-readable storage medium storing a program code to determine a course of a lane of a vehicle, the program code, when executed by a processor, causing the processor to perform:
recording a first marking course of a first marking of the lane and a second marking course of a second marking of the lane; checking the first marking course and the second marking course for plausibility in order to determine a plausible marking course; and determining the lane course based on a previous width of the lane and a plausible marking course in response to at least one marking course proving to be implausible in the checking step.
