First Claim
1. A method for warning a driver of a vehicle of lane departure, the method comprising:
- detecting lane departure by the vehicle using a first analyzer based on at least one of image data, vehicle data, and driver activity;
issuing a warning to the driver as a function of the detection using the first analyzer;
evaluating a driving situation using a second analyzer before or after the detecting, wherein when the evaluating is performed after the detecting, the second analyzer carries out a suppression of the warning as a function of the evaluation, and wherein when the evaluating is performed before the detecting, the second analyzer suppresses a detection of lane departure as a function of the evaluation.

Abstract
A method and device for warning a driver of lane departure, wherein a first analyzer is used to detect the vehicle'"'"'s lane departure based on image data and/or vehicle data and/or driver activity. The driver then receives a warning as a function of the detection by the first analyzer. In addition, a second analyzer for evaluating the driving situation is provided, which either performs the evaluation of the driving situation after the detection and via which the warning is suppressed as a function of the evaluation, or which alternatively performs an evaluation of the driving situation before the detection and via which a detection of lane departure is suppressed as a function of the evaluation. As a result, the driver receives highly reliable warnings of lane departure, and furthermore thanks to the evaluation of the driving situation erroneous warnings may be recognized highly reliably and as a result suppressed, so that the driver is not distracted unnecessarily and the product enjoys a high acceptance level among users.
