摘要:
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.

A system is provided for varying the width of a molded concrete slab on the fly as the slab is being molded. Position and height of the paving machine relative to an external reference system are determined and controlled using at least two 3D stringless reference objects. An additional sensor provides a signal corresponding to a frame width and thus a concrete slab width, and an actuator controls the frame width actively as the paving machine advances.

A self-propelled construction machine has an image capturing unit for capturing an image of the terrain, a display unit on which the captured image is displayed, and a data processing unit. In the displayed image, objects that are relevant to the building project, for example manhole covers, water inlets or curbs, are identified and a spatial data set containing information regarding the position of the identified objects in a reference system which is independent of the movement of the construction machine is determined from the image data of the capturing unit. The construction machine is then controlled in order to carry out translational and/or rotational movements on the terrain and/or to install a structure on the terrain or to alter the terrain on the basis of the spatial data set. As a result, the previously identified objects can be taken into account in the building project.

An automotive construction machine, in particular a slipform paver or a road milling machine, has at least one front running gear and one rear running gear in the working direction. As the construction machine advances, the lifting systems of the front running gear are extended or retracted such that the machine frame remains in a predetermined orientation to the surface of the ground in the longitudinal direction. Irregularities in the ground surface are detected as the construction machine advances, and the position of the front lifting systems, predetermined by the control or regulating unit, is monitored to keep the machine frame in a predetermined orientation to the ground surface. As the construction machine advances, the control of the rear lifting systems is engaged with a time delay subject to the control of the front lifting systems. Consequently, the working system of the construction machine, in particular the concrete mold or milling drum, is adjusted to the correct height with respect to the ground surface, so that the working system does not copy the course of the ground.

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.

The invention relates to a self-propelled civil engineering machine, and in particular to a slipform paver, road paver or road milling machine, and to a method of controlling a self-propelled civil engineering machine. The civil engineering machine according to the invention has a control unit which is 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 (X, Y, Z) independent of the position and orientation of the civil engineering machine. The reference system (X, Y, Z) independent of the machine-related reference system (x, y, z) may be selected as desired, and there is thus no need for the positions of various reference points to be plotted on the ground.

A system is provided for monitoring spacing during working operation between a first vehicle and at least one further self-propelled vehicle. A beam source is on one vehicle (source vehicle). A sensor arrangement on another vehicle (target vehicle) extends along a sensor axis. In a predetermined reference state, with the vehicles having a predetermined reference spacing apart, the beam source radiates toward the target vehicle electromagnetic radiation such that a predetermined sensor-axial reference detection region on the sensor arrangement is irradiated by the beam source. A change in the vehicle spacing results in a change, along the sensor axis, in the position of the detection region on the irradiated sensor arrangement, and thus in a change in the detection state of the sensor arrangement. Based on the detection state which depends on an actual spacing of the source and target vehicles, a spacing signal is generated with vehicle spacing information.

In the method for milling off traffic areas with a milling drum of a milling machine, the following steps are provided: obtaining and storing target profile data (x, y, Ft(x,y)) of a desired target profile (8) of a surface of the traffic area (3) in target condition, wherein target values (Ft(x,y)) for a locally desired milling depth (Ft), which are specified relative to the surface of the traffic area (2) to be worked, are assigned to position data (x, y) in an in particular stationary coordinate system independent of the milling machine (6), determining the current x, y position of the milling drum (4) in the coordinate system and detecting the milling depth (Ft′) of the milling drum (4) currently adjusted relative to the surface of the traffic area (2, 3), during the milling operation, controlling the milling depth (Ft) of the milling drum (4) as a function of the target value (Ft(x,y)) for the locally desired milling depth (Ft) assigned to the current x, y position of the milling drum (4) and the currently detected milling depth (Ft′), updating the target profile data (x, y, Ft(x,y)) in the current position (x, y) of the milling drum (4) on the worked traffic area (3) by the currently actually milled milling depth (Ft), and storing the updated target profile data (x, y, Ft(x,y)).

A slip form paver machine includes a slip form mold and left and right side form assemblies closing the slip form mold on the sides. Each side form assembly includes a mounting portion, a side form, and a side form actuator configured to move the side form up and down relative to the mounting portion to adjust a height of the side form relative to the ground surface. At least one side form height sensor is configured to detect the height of the side form. A controller is configured to receive input signals from the side form height sensors and to send control signals to the side form actuators to control the height of the side forms relative to the ground surface.
