Lane monitoring method and lane monitoring system for a vehicle

摘要

A lane monitoring method for a vehicle includes: detecting a lane of the vehicle with the aid of a camera of the vehicle; recording driving status measuring signals of the vehicle; evaluating the driving status of the vehicle according to at least one lane departure criterion; upon meeting the lane departure criterion, checking whether decision criteria for detecting an intentional trajectory shortening maneuver have been met; and generating a lane departure warning signal as a function of the evaluation according to the lane departure criterion, the output of the lane departure warning signal being suppressed if an intentional trajectory shortening maneuver is detected.

1. A lane monitoring method for a vehicle, comprising:
detecting a lane of the vehicle with the aid of a camera located on the vehicle;
wherein the camera is a rear view camera monitoring a detection area behind the vehicle; andbased on output signals of the camera, (i) a course of roadway lines located behind the vehicle and which define the lane of the vehicle is ascertained, and (ii) a forward course of the lane of the vehicle is estimated by at least one of extrapolation and affirmation; recording at least one driving status measuring signal of the vehicle; evaluating a driving status of the vehicle according to at least one lane departure criterion; and generating a lane departure warning signal as a function of the evaluation of the driving status according to the lane departure criterion; wherein, if the lane departure criterion is met, a determination is made whether at least one decision criterion for detecting an intentional trajectory shortening maneuver has been met, and if an intentional trajectory shortening maneuver is detected, an output of the lane departure warning signal is prevented.
