Patent number: 8896433Abstract: In a method and apparatus for assisting the driver of a vehicle in maintaining a traffic lane limited by traffic lane markings, the traffic lane markings and the position of the vehicle in the traffic lane are detected. Upon an actual or impending change of traffic lanes a lane change warning is output to the driver of the vehicle in a first step, and a course correcting actuating intervention counteracting the lane change is carried out in a second step. The actuating intervention is carried out only if the change of traffic lanes is impermissible due to the type of traffic lane marking to be crossed during the traffic lane change, or if the lane change is not possible without danger due to collision-endangering objects present on the side of the traffic lane.Type: GrantFiled: November 26, 2008Date of Patent: November 25, 2014Assignee: Daimler AGInventors: Bernd Danner, Uli Kolbe, Rainer Moebus, Markus Raab, Uwe Regensburger, Reinhold Schoeb, Anke Dorle Dudeck, Lars Dudeck, Sven Gerhard Dudeck
