Abstract:
A swath generation apparatus (SGA) (10) creates a curved swath path (102) for an agricultural vehicle with an associated implement. The SGA (10) determines orthogonal values of the vehicle heading at at least two location data points (104). At one data point, the operator may apply an adjustment input (254) for the vehicle path for compensating the effects of GPS drift. The SGA (10) modifies the data point positions of the swath path (102) by a portional amount of the orthogonal values based on a difference, relative to the orthogonal coordinate system, between the first and second vehicle headings.
Abstract:
The invention relates to a combination of a self-moving harvesting machine (32) and a transport vehicle (33) which is used to receive harvested crops from the harvesting machine. Said transport vehicle (33) comprises at least one driven and articulated axle, in addition to an electronic control unit (38) which is used to control said driven and articulated axle of the transport vehicle (33). Said control unit (38) is connected to a receiving unit which is used to receive position data of the harvesting machine (32), such that the control unit (38) can be operated in such a way as to automatically control the transport vehicle (33), in relation to a position of the harvesting machine (32), so that it can receive the harvested crops from the harvesting machine (32). According to the invention, the control unit (38) can be operated in such a way that it enables the transport vehicle (32) to be automatically displaced parallel to the harvesting machine (32), and to dock onto the same in order to collect the harvested crops from the harvesting machine (32), said transport vehicle (33) being unmanned.
Abstract:
Beschrieben wird ein Verfahren zur Steuerung eines landwirtschaftlichen Maschinensystems (1) bei der Bearbeitung eines zu bearbeitenden Territoriums (S), bei dem eine Route (R) für das Maschinensystem (1) erstellt wird, welche Nutzfahrspuren (F N ) umfasst, entlang deren das Maschinensystem (1) bei der Bearbeitung des Territonums (S) gefahren wird, und welche Vorgewendefahrspuren (F V ) umfasst, entlang deren das Maschinensystem (1) jeweils von einer Nutzfahrspur (F N ) zu einer nachfolgend zu befahrenden Nutzfahrspur (F N ) gefahren wird, Zum Ende einer Nutzfahrspur (F N ) und/oder während des Abfahrens einer nachfolgenden Vorgewendefahrspur (F V ) und/oder zu Beginn einer nachfolgenden Nutzfahrspur (F N ) wird vom Maschinensystem (1) jeweils automatisch eine Vorgewende-Arbeitsschrittsequenz abgearbeitet. Dabei wird die Vorgewende-Arbeitsschrittsequenz jeweils in Abhängigkeit von der aktuellen Position des Maschinensystems (1) und in Abhängigkeit von der nachfolgend zu befahrenden Nutzfahrspur (F N ) dynamisch aktualisiert und abgearbeitet. Außerdem wird ein entsprechendes automatisches Steuersystem (2) zur Steuerung eines landwirtschaftlichen Maschinensystems (1) beschrieben.
Abstract:
An earthmoving machine (102) including a control system (200) is disclosed. The machine (102) comprises first and second satellite navigation antennas (104,106) mounted in a longitudinal direction on the earthmoving machine (102). A third satellite navigation antenna (108) is mounted on a pole (110) attached to an operational element (112) of the earthmoving machine. In one embodiment, the earthmoving machine (102) is a bulldozer and the operational element is a blade of the bulldozer. The machine (102) further comprises a gravity reference sensor (210) and a plurality of gyroscopes (214) mounted on the machine. A computer processor (222) generates control signals based on sensor data received from the various components. The disclosed system and method allows for dynamically stable operation of the earthmoving machine (102) at relatively fast speeds without the development of unwanted oscillations.
Abstract:
The invention relates to a method of scanning a complex surface (202) defined at least partially by a physical barrier and/or comprising obstacles. The inventive method comprises the following steps: (a) a step consisting in sufficiently scanning a first zone such as to obtain absolute location data in said zone, thereby enabling same to be exhaustively scanned; (b) a step consisting in selecting a second zone (206i+1) of the complex surface, having a reduced size and a suitable shape, and repeating step (a) for said second zone; and (c) a step consisting in repeating step (b) as many times as is necessary for the whole complex surface to be scanned.
