  • Patent number: 10808367
    Abstract: A self-propelled construction machine comprises a control unit configured in such a way that a point of reference on the construction machine moves along a route. A processing unit is configured in such a way that the position of at least one kink on the target route is determined from the imported data, at least a portion of the target route is displayed, and, for the section of the target route in which the target route has the kink, an interpolation curve that is substantially free of kinks is calculated. The relevant section of the target route is replaced by the interpolation curve for the determination of a modelled route. The control of the drive device is then not based upon the predetermined target route, but rather the modelled target route.

  • 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.

  • 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.

  • Patent number: 10745869
    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: 10704209
    Abstract: A slipform paver comprises a machine frame carried by rolling assemblies, at least two of which being drivable and at least one being steerable, as well as comprising a support arranged on the machine frame for a slipform mould and a controller for controlling the rolling assemblies to adjust the velocities of the drivable rolling assemblies and the steering angles of the one or more steerable rolling assemblies. The controller is configured such that, when the steering angles of the one or more steerable rolling assemblies change, the velocities of the drivable rolling assemblies are adjusted so as to reduce the change in the velocity at which a reference point referring to the support for the slipform mould will move along a predefined trajectory, said change in velocity being caused by changing the steering angle. The quality of the concrete profile produced by the slipform paver is thereby improved.
