Storing the course of a paving edge to control a lateral extension position of a paving screed of a road paver

Abstract

A method for operating a road paver with a laterally extendable paving screed includes performing a paving run along a paving path which extends along a paving edge. During the paving run, an edge sensor attached to the road paver detects the paving edge at a position located ahead of a rear edge of the paving screed with respect to a paving direction. During the paving run, data is stored based on the detection of the paving edge, from which data a course of the paving edge can be reconstructed during the paving run in a current paver-fixed coordinate system. During the paving run, a lateral extension position of the paving screed is adjusted to a desired lateral distance between the rear edge of the paving screed and the paving edge on the basis of the stored data.
