Abstract
A method and a device for predicting the future course of a roadway for a transportation vehicle driving on a road, wherein the road has a first section, a bend and a second section, and the bend is arranged between the first and the second section. The method determines an approximated course of a road derived from a digital map material using an original clothoid segment, wherein the clothoid segment has a starting point on the first section, an end point on the second section, and the clothoid segment sweeps over the angle defined by the bend between the first and the second section, and continuously corrects the original clothoid segment by subsequent corrective clothoid segments, wherein the corrective clothoid segments take into account the curvature of the route actually traveled by the transportation vehicle after the starting point.
