Das Verfahren (500) umfasst einen Schritt des Einlesens (510) eines Umfelderfassungssignals einer Umfelderfassungseinheit (130) der ersten Arbeitsmaschine (110), wobei das Umfelderfassungssignal eine Umgebung (135) um die erste Arbeitsmaschine (110) repräsentiert. Ferner umfasst das Verfahren (500) einen Schritt des Erkennens (520) der zweiten Arbeitsmaschine (100) anhand eines Umrisses und/oder einer Form und/oder einer Kontur der zweiten Arbeitsmaschine (100) unter Verwendung des Umfelderfassungssignals. Schließlich umfasst das Verfahren einen Schritt des Führens (530) der ersten und/oder zweiten Arbeitsmaschine (100, 110), derart, dass zumindest innerhalb eines vordefinierten Zeitintervalls die erste Arbeitsmaschine (110) in einem vorbestimmten seitlichen oder lateralen Abstand (150) zu der zweiten Arbeitsmaschine (100) fährt, um die Fahrt der ersten und/oder zweiten Arbeitsmaschine (100, 110) zu regeln.
Abstract:
Die vorliegende Erfindung bezieht sich auf ein Verfahren (700) und eine Vorrichtung (104) zum Führen einer Landmaschine (104). Das Verfahren (700) weist einen Schritt des Erfassens (702), einen Schritt des Ermittelns (704), einen Schritt des Einlesens (706) und einen Schritt des Bestimmens (708) auf. Im Schritt des Erfassens (702) wird eine Referenztrajektorie (102a) der Landmaschine (104) erfasst, während die Landmaschine (104) auf einer Referenzbahn (108) bewegt wird. Im Schritt des Ermittelns (704) wird ein Abstand (110) der Landmaschine (104) von der Referenztrajektorie (102a) nach einem Wendemanöver der Landmaschine (104) erfasst, um eine Abstandsinformation zu erhalten. Im Schritt des Einlesens (706) wird ein, durch einen Bediener der Landmaschine (104) eingegebener, geänderter Abstandswert eingelesen, der einen geänderten Abstand (112) der Landmaschine (104) zur Referenztrajektorie (102a) repräsentiert. Im Schritt des Bereitstellens (708) wird ein Steuersignal zum Führen der Landmaschine (104) auf einer Führungsbahn bereitgestellt, wobei die Führungsbahn in dem geänderten Abstand (112) zur Referenztrajektorie (102a) verläuft.
Abstract:
A system is provided for processing container-grown plants positioned in a given area. The system includes a processing station positioned in the area for processing the container-grown plants. It also includes one or more autonomous mobile container handling robots configured to: (i) travel to a source location in the area and pick up a container-grown plant, (ii) transport the container-grown plant to the processing station where a process is performed on the container-grown plant, (iii) transport the container- grown plant from the processing station to a destination location in the area, (iv) deposit the container-grown plant at the destination location, and (v) repeat (i) through (iv) for a set of container-grown plants in the source location.
Abstract:
A control system and method is provided to control a longitudinal position of a transport vehicle (20) relative to a harvester (10) during an unload on the go operation and to control both the lateral position and the longitudinal position of a transport vehicle relative to a harvester (10) during an unload on the go operation to evenly fill a receiving area of the transport vehicle (20) with crop material from the harvester (10). The longitudinal position of the transport vehicle (20) is maintained within an acceptable range by adjusting the velocity of the transport vehicle (20). The receiving area of the transport vehicle (20) can be more evenly filled with crop material by adjusting the lateral position and the longitudinal position of the transport vehicle (20) within predetermined trim distances associated with the receiving area of the transport vehicle (20).
Abstract:
The present invention relates to a method for controlling a self-propelled robot device, such as a robot device for mowing grass, and a control system that carries out the aforementioned method. According to the invention, the self- propelled robot device (10) is driven by an inertial navigation system (24) for a set time period or distance and said device is periodically stopped for rectifying the position and advancing course thereof by means of a satellite detection system (26) : the periodic correction of the inertial navigation system using satellite detections thus prevents course errors from accumulating. The correction based on the satellite detection system can be possibly optimized through a further selection of the obtained values according to a statistical basis. Preferably, the control method according to the invention also provides a procedure for detecting, recording and mapping the operating region (R) wherein the device (10) is operated.
Abstract:
A method for steering an agricultural vehicle comprising: receiving global positioning system (GPS) data including position and velocity information corresponding to at least one of a position, velocity, and course of the vehicle; receiving a yaw rate signal; and computing a compensated heading, the compensated heading comprising a blend of the yaw rate signal with heading information based on the GPS data. For each desired swath comprising a plurality of desired positions and desired headings, the method also comprises: computing an actual track and a cross track error from the desired swath based on the compensated heading and the position; calculating a desired radius of curvature to arrive at the desired track with a desired heading; and generating a steering command based on the desired radius of curvature to a steering mechanism, the steering mechanism configured to direct the vehicle.
Abstract:
A method for improving haul road surface conditions comprises collecting performance data associated with at least one machine operating on a haul route (310) and determining a rolling resistance of each of the at least one machine based on the performance data (320). An average rolling resistance associated with one or more portions of the haul route is determined based on the rolling resistance of each of the at least one machine (330). The one or more portions of the haul route are identified as irregular if the average rolling resistance of the one or more portions exceeds a threshold resistance value (340). A proposed modification to the irregular portion of the haul route is generated (350), and performance of the at least one machine is simulated based on the proposed modification (360). The method also includes outputting results of the simulated performance (370).

A definer (26) for defining a reference row having a reference path that tracks at least a majority of the border. A generator (30) generates tracking rows that track the reference row. The tracking rows comprise at least one inner tracking row and an outer tracking row. Each inner tracking row having at least one inner curve with a lesser radius than an outer tracking row having a corresponding outer curve with a greater radius.
Abstract:
A path planner (10) and a method for determining a path for a vehicle comprises defining a starting point for the vehicle. A termination point is defined. An obstacle detector (14) detects one or more obstacles in a work area between the starting point and the termination point. A boundary zone is defined about each corresponding obstacle. Candidate paths are identified between the starting point and the termination point. Each candidate path only intersects each boundary zone once for each corresponding obstacle. An economic cost is estimated for traversing each candidate path or a portion thereof between the starting point and the termination point. A preferential path is selected from the identified candidate paths based on the preferential path being associated with a lowest estimated economic cost.
