Abstract

A method and a device for driver information, according to which a warning is produced on the basis of the lane information which indicates crossing of the lane edge. Upon branching of a roadway line, the particular outer lines are used as lane edge markings as the basis for the lane departure warning.

Claims

1. A method for providing driver information, comprising:

providing a warning for a driver of a vehicle when the vehicle at least one of (a) threatens to depart from a lane and (b) departs from a lane, the warning being ascertained on the basis of a pair of roadway edge lines defining a lane, wherein in the event of recognizing branching of at least one of the roadway edge lines into multiple branch lines, a branch line further away from the vehicle is selected to ascertain the warning.

2. The method according to claim 1, wherein the branch line further away from the vehicle is used as a basis of the warning for at least one of a predefined driving distance and a predefined driving time.

3. The method according to claim 1, wherein a warning is output if the vehicle at least threatens to cross a selected line.

4. The method according to claim 1, wherein the warning is at least one of (a) optical, (b) acoustic, (c) haptic, and (d) representative of a steering intervention counteracting a crossing of the roadway edge line.

5. The method according to claim 1, wherein a line further from the vehicle is defined as the roadway edge line after said warning.

6. A device for providing information to a driver of a vehicle, comprising:

means for providing a lane departure warning for a driver of a vehicle when the vehicle at least one of (a) threatens to depart from a lane and (b) departs from a lane; and

means for detecting at least a pair of roadway lines as roadway edge lines defining a lane, wherein in the event of recognizing branching of at least one of the roadway edge lines into multiple branch lines, a branch line further away from the vehicle is selected to ascertain the lane departure warning.
