Method and device for driver information
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.

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.
