  • Publication number: 20240084529
    Abstract: A system is provided for determining a volume of material milled, or a surface area milled, by a construction machine having a milling drum. The volume of material milled is determined as a function of a cross-sectional area of material to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling. The cross-sectional area is determined in part by direct machine observation of one or more profile characteristics of a ground surface in front of the milling drum. The surface area milled is determined as a function of the width of the area to be milled in front of the milling drum and a distance traveled by the construction machine while actively milling.

  • Patent number: 11866893
    Abstract: The invention relates to a self-propelled construction machine, comprising a machine frame supported by a chassis having wheels or crawler tracks. The basic principle of the invention involves determining a variable ? which is characteristic of the milling profile on the basis of a functional relationship between the variable which is characteristic of the milling profile and the advance speed v and/or milling drum rotational speed n. The variable ? which is characteristic of the milling profile is a correction variable for adjusting the height of the milling drum with respect to the surface of the ground.

  • Patent number: 11761155
    Abstract: A self-propelled construction machine for milling a ground surface is provided with a machine frame, a working drum, and a transport conveyor with a discharge end from which worked-off milling material is dischargeable onto a point of impingement on a loading surface of a transport vehicle, wherein the transport conveyor is laterally slewable to a slewing angle about at least a first slewing axis. A controller is configured, during an initialization process, to specify a command variable within a coordinate system, the coordinate system being stored during the initialization process with its origin at a starting point associated with the machine. The controller is further configured during a working process, wherein the coordinate system is stationary, to automatically control the slewing angle corresponding to detected changes in position and/or orientation of the machine and relative to the command variable.

  • Patent number: 11761763
    Abstract: A civil engineering machine has a machine control unit configured to determine data which defines the position and/or orientation of a reference point on the civil engineering machine in relation to a reference system independent of the position and orientation of the civil engineering machine. A geometrical shape to be produced on the ground is preset in either a machine control unit or a field rover control unit. The field rover is used to determine a position of at least one identifiable point of the preset geometrical shape in the independent reference system. Curve data defining a desired curve in the independent reference system, corresponding to the preset shape, is determined at least partially on the basis of the position of the at least one identifiable point of the preset geometrical shape in the independent reference system.
