Abstract:
In one embodiment, a control system for a land machine, the control system comprising: a position indication component configured to generate position information that indicates a current geographic position of the machine; and a control unit configured to: receive the position information from the position indication component; and change a control state of the machine by either disabling, or enabling engagement of, an automatic steering function of the machine depending on the position information.
Abstract:
A single imaging device collects image data of a storage portion. A container module identifies a container perimeter of the storage portion in at least one of the collected image data. A spout module is adapted to identify a spout of the transferring vehicle in the collected image data. An arbiter determines whether to use the image data based on an evaluation of the intensity of pixel data or ambient light conditions. An alignment module is adapted to determine the relative position of the spout and the container perimeter and to generate command data to the propelled portion to steer the storage portion in cooperative alignment such that the spout is aligned within a central or target zone of the container perimeter.
Abstract:
A mode controller (225) determines whether to use an automated control mode of the spout or operator-directed manual control mode of the spout, based on a first operational status of a first location determining receiver (42) associated with the propelling vehicle, a second operational status of a second location determining receiver (142) associated with the harvesting vehicle, a third operational status of the imaging device or devices (10, 12). In the automated control mode, an image processing module (18) is adapted to facilitate the determination of the relative position of the spout and the storage portion and to generate command data place the storage portion and spout in relative cooperative alignment for transferring of material into the storage portion.
Abstract:
Die vorliegende Erfindung bezieht sich auf ein Verfahren (200) zum Koordinieren einer Transportlogistik mit zwei Schritten des Empfangens und zwei Schritten des Sendens. Im Schritt des Empfangens (202) eines Anforderungssignals wird ein Anforderungssignal von einer Arbeitsmaschine empfangen. Das Anforderungssignal signalisiert einen Transportbedarf der Arbeitsmaschine. Im Schritt des Sendens (204) eines Steuersignals wird ein Steuersignal an eine Transportmaschine gesendet, um die Transportmaschine zu der Arbeitsmaschine zu führen, wenn das Anforderungssignal empfangen wurde. Im Schritt des Empfangens (206) eines Koppelungssignals wird ein Koppelungssignal empfangen, wenn die Transportmaschine eine Ladeposition relativ zu der Arbeitsmaschine erreicht hat. Im Schritt des Sendens (208) eines Ladesignals wird ein Ladesignal gesendet, um einen Ladevorgang zum Decken des Transportbedarfs zu starten, wenn das Koppelungssignal empfangen wurde.
Abstract:
An irrigation system includes a central pivot and a series of mobile towers connected to the central pivot and to one another by support structure. Each mobile tower has wheels and a motor for driving at least one of the wheels. A control system operates the motors to maintain alignment of the mobile towers and the central pivot while preventing power usage of the system from exceeding a maximum power threshold. The control system determines in which sequence to operate the motors to maintain alignment of the mobile towers while operating no more than a selected number of the motors simultaneously.
Abstract:
A control system and method is provided to control the trajectory of a transport vehicle (20) to follow the trajectory of a harvester (10). The harvester can send control information such as the harvester's current position and future position waypoints to the transport vehicle. The control system can then use the information from the harvester to determine the trajectory for the transport vehicle.
Abstract:
In a wireless communication system for agricultural vehicles, each vehicle (10,12) has a global positioning system (GPS), a multi-channel transmitter/ receiver (Tx/Rx) module having a limited communication range, and a signal processor connected to the Tx/RX module. The transmitter is controlled by the signal processor to transmit on a predetermined communication channel a signal comprising, at least, a unique vehicle identifier and a signal indicating the current positional co-ordinates of the vehicle. The signal processor also analyses the signals received from other vehicles within the communication range and determines from the identifier and the positional co-ordinates data when another vehicle is ready to perform a joint operation with the vehicle. In the invention, prior to initiation of ajoint operation, the communication system is switched to a different communication channel.
Abstract:
An automatic control system for passive, towed implements is described. The system provides a strategy for optimal control of a towed implement using a nudge input to an autopilot-controlled tractor. Implement path-tracking error, as measured by a GNSS receiver, is consistently corrected to zero.
Abstract:
Die Erfindung betrifft ein Verfahren zum Erkennen einer Position bezüglich eines definierten Bereichs (4), insbesondere in einem mobilen Arbeitsgerät, mit folgenden Schritten: - Bereitstellen (S1) eines Stromsignals in einem Begrenzungsleiter (3), der den definierten Bereich (4) umgibt, entsprechend eines bereitgestellten Begrenzungssignals, wobei das Begrenzungssignal (BS) einem Pseudozufallssignal entspricht; - Empfangen (S3) eines Detektionssignals eines durch das Stromsignal in dem Begrenzungsleiter (3) generierten magnetischen Feldes; - Generieren eines rekonstruierten Begrenzungssignals aus dem Detektionssignal; - Bereitstellen (S4) eines Referenzsignals (RS), das ein dem bereitgestellten Begrenzungssignal (BS) entsprechendes Bitmuster aufweist; - Durchführen (S5) eines Korrelationsverfahrens, um einen zeitlichen Korrelationsversatz zwischen dem Referenzsignal und dem rekonstruierten Begrenzungssignal und einen Korrelationswert (KKF) zwischen dem Referenzsignal (RS) und dem rekonstruierten Begrenzungssignal (BS), die um den ermittelten Korrelationsversatz zueinander verschoben sind, zu ermitteln; - Bestimmen (S7) einer Position innerhalb oder außerhalb des definierten Bereichs (4) abhängig von dem ermittelten Korrelationswert (KKF).
Abstract:
A method of controlling outdoor ground processing operations of two or more work vehicles (15, 260, 270, 280, 290, 300), involves running a computer model (100, 110, 120) of the operations using a number of candidate schedules of the ground processing operations using predicted conditions, the operations involving work vehicle movements and work vehicle processing tasks, at least one of the operations for one of the work vehicles being a dependent operation, being dependent on another (25) of the work vehicles. An overall schedule for the operations is generated and used to control actual execution of the ground processing operations by the work vehicles. The computer model is updated as changes in the conditions occur as monitored during the actual execution, and used to adapt the actual execution of a remaining part of the ground processing operations.
