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.
