Abstract: A system and computer-implemented method for automatically controlling a construction process of a road section, the section comprising a plurality of subsections, the construction process comprising processing a road surface material layer using a paver with a height-adjustable screed, the paver travelling along a predetermined path, the method comprising receiving construction design data comprising information about the path and about a nominal surface and a nominal layer thickness of the paved road surface material layer for a multitude of positions along the path, receiving a set of rules comprising different priorities for each of the plurality of subsections, continuously receiving position data indicating a current position of the screed, continuously receiving thickness data indicating a current layer thickness of the paved road surface material layer, calculating a height-adjustment of the screed, generating, based on the calculation, control data to adjust a height of the screed.

Abstract: A system for positioning of a road construction machine of the type paver. The system comprises a first measuring unit configured for continuously generating first measuring data in a first detection range during a movement of the road construction machine and comprising at least a first camera and a first LiDAR sensor module, wherein camera and LiDAR data are recorded covering the first detection range with minimum repetition rate and minimum resolution, and several markers. The system further comprises a data memory, wherein the data memory has stored a 3D design model referenced with respect to a 3D construction site coordinate system and information about a known absolute reference of the several markers in the 3D construction site coordinate system, and a computing unit.

Abstract: A device for controlling an air stream includes a control slat swivelly mounted in a housing and second slats extending orthogonally with respect to the control slat and swivelly mounted in the housing. The direction of the air stream exiting from the housing and the quantity of air streaming out can be set by the slats. An operating element is arranged orthogonally with respect to the longitudinal axis of the control slat to swivel and is coupled to a first bevel gear rotatably mounted on the bearing web and to the control slat. The first bevel gear is in engagement with a second bevel gear which is coupled to a lever arrangement which has at least one rotatably mounted first coupling member which is coupled to at least one first coupling rod and the at least one first coupling rod is coupled to the second slats.
