A method for adapting a leveling control of a road finishing machine comprises: detecting first ground profile data of a first ground profile of a foundation in a surrounding area of the road finishing machine at point in time t0, wherein the road finishing machine is located at position x0; detecting second ground profile data of a second ground profile of the foundation in a surrounding area of the road finishing machine at point in time t1, wherein the road finishing machine is located at position x1, and the second ground profile partially overlaps the first ground profile; determining a translational and rotational matrix which maps a movement of the road finishing machine in space from the point in time t0 to the point in time t1; creating corrected ground profile data from the ground profile data by means of the matrix; determining an analysis region LA comprising at least a section of the first ground profile data L0 and/or a section of the corrected ground profile data; analyzing the analysis region; adapting the leveling control for a distance of the analysis region by means of data obtained in the analysis.
A method for adapting a leveling control of a road finishing machine, comprising:
A road finishing machine comprising a screed and a chassis, wherein the screed is hinged to the chassis by a screed arm via a towing point, and a towing point height is adjustable by a leveling cylinder, wherein the road finishing machine furthermore comprises at least one leveling sensor, at least one ground profile scanner, and a control system with a leveling controller configured to control the towing point height taking into consideration data of the at least one leveling sensor, and wherein the control system is configured to parameterize the leveling controller based on data detected with the at least one ground profile scanner and based on a translational and rotational matrix M determined from that data, which maps a movement of the road finishing machine in space from a point in time t0 to a point in time t1.
