A method for ascertaining a soil condition includes observing via a detection device, including a sensor, a kinematic behavior of a track drive caused by sinking when driving on a compressible underlying surface, and determining via an assessment device, including a processor connected to memory, at least one parameter characterizing the soil condition based in part on the observed kinematic behavior of the track drive.

A method is provided for identifying an obstacle during a work operation of a tractor and attached implement combination. The method includes detecting an object during the work operation, and identifying the detected object as an obstacle in dependence on the predefined classification parameter for classification of the detected object or a predefined work parameter of the tractor or the implement.

A method is provided for dynamically determining a tire longitudinal force. The method includes determining a tire acceleration variable by an acceleration sensor arranged in a tire bead, determining a first time interval between a tire contact patch entry point and an acceleration vertex by a processor unit, and determining a second time interval between the acceleration vertex and a tire contact patch exit point by the processor unit. The method also includes determining a magnitude or direction of a tire longitudinal force variable comprising a tire longitudinal force by the processor unit from a symmetry shift detected between the first and second time intervals.

A method of communicating information via optical data transmission between two utility vehicles includes providing a control unit on a first utility vehicle, a work light on the first utility vehicle, and a second utility vehicle. The method also includes generating activation signals by the control unit of the first utility vehicle in dependence on transmission data to be transmitted, activating the work light by the activation signals, and emitting light signals via the activated work light to the second utility vehicle. The light signals represent the transmission data.

A method for adapting a tire inflation pressure of an agricultural vehicle includes ascertaining a current vehicle position by a navigation system, correlating the current vehicle position by a control unit with a cartographically captured field boundary, detecting a travel-induced entry into a cultivation region surrounded by a field boundary, and selecting a set tire inflation pressure designated for field cultivation from a database by the control unit. The method further includes applying the selected set tire inflation pressure to at least one tire of the agricultural vehicle by a tire-pressure regulating system.

A method is provided for controlling engine speed of a drive engine of a utility vehicle having a drivable loading apparatus. The method includes detecting or predicting a driving movement of the loading apparatus, and requesting an increase of engine speed if the movement of the loading apparatus is predicted or detected.

A system for influencing a vehicle position when travelling along a subsurface includes a vehicle structure including left and right wheels, a tire inflation system for the supply of the corresponding tires of each individual wheel with a specified tire inflation pressure, and a sensor device for determining a transverse tilt of the vehicle structure with respect to the travelled subsurface. The sensor device is configured to provide a transverse tilt magnitude that reflects the determined transverse tilt and operably communicates it to a control unit. The control unit operably adapts the tire inflation pressure specified for the left and right wheels by controlling the tire inflation system in accordance with the transverse tilt magnitude in such a way that the vehicle structure is tilted in the sense of a reduction of the determined transverse tilt with respect to the travelled subsurface.

A method for making available a ballasting proposal for an agricultural tractor includes providing an implement for the tractor, calculating a target tractive power for the implement for each axle of the agricultural tractor, and deriving a target value for an axle load to be maintained on each axle based upon a function of the calculated target tractive power. The method further includes determining an actual axle load on each axle, comparing the target value to the actual axle load, calculating an axle ballasting value based on a result of the comparing step required to maintain the target valve, and outputting the ballasting value.

A method for distributing delivered crop during a spreading operation includes providing an agricultural utility machine and a spreading tool movably mounted thereto, automatically controlling a motion of the spreading tool, and spreading crop by the spreading tool.

A device for tire pressure monitoring of a vehicle tire of a vehicle system includes a tire inflation system in communication with the vehicle tire. A control unit calculates a set pressure value to be maintained for the tire pressure. A storage unit is in communication with the control unit such that the control unit adjusts the calculated set pressure value in dependence on an operating state classification derived from operating state parameters of the vehicle system. The control unit determines a geoposition of the vehicle system correlating with the derived operating state classification and stores it with the operating state classification in the storage unit. The control unit further recalls from the storage unit the relevant operating state classification for purposes of anticipatory adjustment of the set pressure value of the tire pressure when a renewed approach of the vehicle system to the stored geoposition is detected.

A system for monitoring tire pressure of at least one vehicle tire of a utility vehicle includes a pressure sensor for detecting an internal tire pressure of the at least one vehicle tire and an electrically controllable tire inflation system for varying the internal tire pressure. The system also includes a monitoring unit disposed in communication with the pressure sensor and the tire inflation system. The monitoring unit identifies a defect-induced loss of pressure in the at least one vehicle tire based on the detected internal tire pressure, determines a temporal progression of the detected defect-induced loss of pressure, calculates a volume flow necessary for continuous compensation of the pressure loss based on the temporal progression, and controls the volume flow into the at least one vehicle tire via the tire inflation system.
