Abstract: A method and a device are proposed for driver information and for a reaction upon the leaving of the traffic lane by the vehicle. The diver warning and the driver intervention are a function, in this context, of the driving situation, especially of the type of an edge marking of the traffic lane.

Abstract: A method and a device for course prediction in motor vehicles, which have a position-finding system for objects situated in front of the vehicle, where a function describing the path of the roadway is calculated on the basis of measured distance and angular data, in that several fixed targets are identified and tracked and supplied (subjected) to a statistical evaluation, a plausibility criterion being that at least one parameter of the functions, which describe these roadway paths, has a significant frequency maximum at the value which corresponds to the real roadway path. At the beginning of the evaluation, the frequency distribution for all parameters is set to a predefined frequency value, and the frequency values of the parameters are reduced or increased by a predefined numerical value as a function of the position of fixed targets or vehicles.

Abstract: A method for travel course prediction in a motor vehicle having a position finding system for objects situated ahead of the vehicle is provided. In accordance with the method, a function describing the shape of the roadside is calculated on the basis of measured distance data and angle data for stationary roadside targets, wherein multiple stationary targets are identified and tracked. The path of the road is estimated for various subsets of the set of tracked stationary targets, under the assumption that these stationary targets are situated along the roadside, and roadside targets are differentiated from interfering objects on the basis of the plausibility of the resulting possible shapes of the roadside, the most probable shape of the roadside being determined on the basis of the roadside targets.

Abstract: A method and a device for driver information and for a reaction upon leaving the traffic lane by a vehicle. In this context, the course of at least one edge marking of the traffic lane is ascertained, the track of the vehicle that is to be expected is determined, and as a function of these variables the possible leaving of the traffic lane by the vehicle is ascertained. In the determination of the track of the vehicle, future reactions of the driver are taken into consideration.

Abstract: The present invention relates to a method and a device for the lateral guidance of a vehicle. A warning device that outputs a warning signal when straying from a traffic lane is able to be turned off by a switching means when driving on a road that is not suitable for lateral guidance, in particular an inner-city road, and be turned on again when reaching a road that is suitable for lateral guidance.

Abstract: A method and a device for warning a driver, the magnitude of the generated warning signal being a function of the probability of the driver inattentiveness.
