  • Publication number: 20200407928
    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: 10794010
    Abstract: The invention relates to a planning system and method for operating one or more road milling machines. In that context, material properties of a road are captured and are geographically associated with one or more roads or road segments. Based on the material properties, an expected milling output of a road milling machine is ascertained, in the context of carrying out milling tasks on the road, or an expected wear on the milling tools. An optimized sequence of milling tasks to be carried out is created on the basis of those data. Accordingly, the invention may enable optimized deployment of the one or more road milling machines and of resources necessary for carrying out the road milling tasks. Aspects of the planning system may be remotely implemented for centralized application with respect to each of the road milling machines, or locally implemented for individual road milling machines.

  • Publication number: 20200308807
    Abstract: A construction machine is provided with a control device having an operating panel with operating elements, which can assume numerous switching states/positions, a control and monitoring unit for controlling machine components via control signals signalling the switching state/position of associated operating elements, and a display/signal unit interacting with the control and monitoring unit. The control device provides first and second signal transmission paths for transmitting a first control signal signalling the switching state/position of a first operating element and a second control signal signalling the switching state/position of a second operating element, respectively. The control signals are checked for the existence of a plausibility criterion. If the plausibility criterion is not met, signal transmission over one or the other signal transmission path is deactivated, wherein the functionality of the relevant component is checked.

  • Patent number: 10746546
    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.
