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.
