摘要:
A system for determining the relative position of first and second farm vehicles, each equipped with a satellite-supported position sensing device. A data transmission link transmits position data between the vehicles, and a computer on one of the vehicles determines data with respect to the relative position of the vehicles. A control device responsive to satellite signal quality assures that the two position sensing devices operate in the same reception modes for improved accuracy.

A preliminary guidance data is determined for the vehicle during an evaluation time window. A vision module collects vision data from a vision module during the evaluation time window. Vision guidance data is determined from the collected vision data. A vision quality estimator estimates vision quality data for at least one of the vision data and the vision guidance data during the evaluation time window. The vision quality data is based on a cross correlations and an r-squared value. An adjuster adjusts the preliminary guidance data to a revised guidance data based on the vision guidance data such that the revised guidance data is registered with or generally coextensive with the vision guidance data, if the vision quality data exceeds a minimum threshold.
摘要:
A system and method provide for precision guiding of agricultural vehicles along a series of adjacent paths to form rows for cultivating a field. In one aspect of the invention the vehicle is moved along a first path while receiving positioning information from a navigational system (e.g., RTK GPS). This positioning information is stored in a processor and is used by the processor to compute a second path adjacent to said first path by calculating piecewise perpendicular offsets from the first path at multiple locations along the first path. The process is repeated to compute a third and subsequent paths so as to cover the field. Because of the offset process, the field may be covered with paths that have varying curvature along their length, while providing substantially no gaps or overlaps in the coverage of the field. In another aspect of the invention, the system may propose alternative paths and the user can intervene by steering the vehicle or using a graphical user interface to select among the alternative paths. A still further aspect of the invention allows for the recording of the paths that provide coverage of a field in the form of a template. This template can then be used to cause the vehicle to automatically steer along a previously calculated path in subsequent operations on the field, and in subsequent years.

In a route planning system and method for agricultural working machines, a defined working width is assigned to the agricultural working machines to generate driving routes in a territory, and dynamic adaptation of the planned driving route is carried out thereby ensuring that the driving route to be covered is flexibly adaptable to changing external conditions such as driving around obstacles, thereby largely relieving the operator of the agricultural working machine of the task of performing laborious steering maneuvers.
摘要:
An adjusting device for a sensor unit mounted on a field machine, or a harvester or tractor, and an associated method for positioning the field machine and sensor unit for locating a working edge of a field. The sensor unit can be mounted on a cutter bar assembly of a field machine via a supporting arm. The sensor unit may be adjusted horizontally or vertically. The sensor produces a signal that is communicated to a steering control unit to guide the field machine along the working edge of the field. The position or alignment of the sensor unit relative to a working edge of the field may be indicated on a two-dimensional display.

An agricultural machine, such as a tractor, is disclosed. The agricultural machine includes a driver assistance system, which comprises an input/output unit for specifying an agricultural working task by an operator and for performing the settings relating to an agricultural working task by the operator. The input/output unit displays virtual operating elements, making the settings possible, and the information corresponding to the settings to be made. Further, the input/output unit includes a set-up assistant unit, which allows the operator to set up the driver assistance system using the virtual operating elements. Further, the set-up assistant unit may be configured depending on the working task determined by the operator.
摘要:
An agricultural machine, such as a tractor, includes a control or regulating system for controlling and regulating a working assembly in order to perform an agricultural work order. The control and regulating system includes at least one control unit with a control program. The control program is configurable and/or loadable as a function of any one, any combination or all of: the agricultural work order; the attachable working assembly; or operator input relating to an agricultural work order.
摘要:
A method for planning a path of a working device includes: generating a polygon corresponding to a work area of the working device and generating an edge data structure based on the polygon; generating a survey area based on the polygon; generating a plurality of survey lines at a predetermined interval in the survey area; detecting at least one intersection between each of edges of the polygon and each of the plurality of survey lines based on the edge data structure; and generating the path of the working device in the work area based on the at least one intersection.
