Method and device for driver information and to react to leaving the lane
First Claim
Patent Images
1. A method for driver information and for a reaction when leaving a traffic lane, comprising:
- performing at least one of providing a warning including driver information and a vehicle intervention as a reaction if a vehicle threatens to leave the traffic lane towards an adjacent lane;
recording at least one boundary of the traffic lane, wherein the at least one boundary is shared with the adjacent lane;
determining whether a boundary marking of the at least one boundary of the traffic lane is one of solid or broken;
identifying a direction of traffic traveling in the adjacent lane sharing the at least one boundary of the traffic lane;
wherein the at least one of the warning and the reaction is a function of both the boundary marking of the at least one boundary of the traffic lane and the direction of traffic traveling in the adjacent lane; and
wherein;
(a) the at least one of the warning and the reaction is generated if the boundary marking of the at least one boundary of the traffic lane is solid; and
(b) the at least one of the warning and the reaction is suppressed if the boundary marking of the at least one boundary of the traffic lane is broken and the direction of traffic traveling in the adjacent lane is in the same direction as the direction of travel of the vehicle.

Abstract
A method and a device are proposed for driver information and for a reaction upon the leaving of the traffic lane by the vehicle. The driver warning and the driver intervention are a function, in this context, of the driving situation, especially of the type of an edge marking of the traffic lane.

9. A device for driver information and for reaction upon leaving the traffic lane, comprising:
-
an evaluation unit that activates at least one of a warning to the driver and a vehicle intervention when a threat of leaving the traffic lane towards an adjacent lane occurs; and a microcomputer including a program that records at least one boundary marking of a boundary of the traffic lane, wherein the boundary is shared with the adjacent lane, and wherein the program determines whether the at least one boundary marking is one of solid or broken, and wherein the program determines a direction of traffic traveling in the adjacent lane sharing the boundary of the traffic lane, wherein at least one of the driver warning and the vehicle intervention is a function of both the at least one boundary marking of the traffic lane and the direction of traffic traveling in the adjacent lane sharing the boundary of the traffic lane; and wherein;
(a) the at least one of the warning and the intervention is generated if the at least one boundary marking of the boundary of the traffic lane is solid; and
(b) the at least one of the warning and the intervention is suppressed if the at least one boundary marking of the boundary of the traffic lane is broken and the direction of traffic traveling in the adjacent lane is in the same direction as the direction of travel of the vehicle.
