Patent ID: 8896433

Claim:
A driver assistance system for a vehicle, said system comprising: a traffic lane recognition device for detecting a traffic lane driven on by a vehicle, based on lane-limiting traffic lane markings, wherein the traffic lane recognition device is configured to recognize, based on a type of the traffic lane markings, whether an abandonment of the traffic lane by passing over the particular traffic lane marking is permissible or impermissible; a warning device for outputting a lane abandoning warning to a driver of the vehicle when a lane abandoning tendency is detected; an object recognition device for detecting lateral objects that are present next to the sensed traffic lane and front objects present forward of the vehicle; and a control device for carrying out a course correcting actuating intervention; wherein, the control device is configured to trigger the actuating intervention subsequent to the output of the lane abandoning warning; the control device determines whether to trigger the actuating intervention based on whether (1) an abandoning of the traffic lane is impermissible, (2) a danger of a collision with a detected lateral object exists, and (3) a danger of a collision with a detected front object exists; the actuating intervention is triggered chronologically after the output of the lane abandonment warning when (a) abandoning of the traffic lane is impermissible, (b) the danger of a collision with a detected front object does not exist, and (c) the danger of a collision with a detected lateral object does not exist; the actuating intervention is triggered chronologically after the output of the lane abandonment warning when abandoning of the traffic lane is permissible and the danger of a collision with a detected lateral object exists; the actuating intervention is suppressed chronologically after the output of the lane abandonment warning when abandoning of the traffic lane is impermissible and the danger of a collision with a detected front object exists; the actuating intervention is suppressed chronologically after the output of the lane abandonment warning when abandoning of the traffic lane is permissible and (1) the danger of a collision with a detected front object does not exist and (2) the danger of collision with a detected lateral object does not exist; the traffic lane recognition device is configured to judge an abandoning of the traffic lane as permissible if the traffic lane marking that will be passed over is a broken line, and to judge it as impermissible if the traffic lane marking that will be passed over is a continuous line; and the danger of collision with a detected front or lateral object exists when there is a probability that the vehicle will collide with the detected front or lateral object within an anticipatory period if the vehicle continues along its current course and no countermeasures are performed.
