This automatic travel system for a work vehicle is provided with: a position information obtaining unit; and an automatic travel control unit that causes a work vehicle to automatically travel along a target path. The automatic travel control unit sets a control target position on the target path including a plurality of work paths arranged in parallel with each other and a plurality of turning paths that connect the work paths in an order of travel of the work vehicle, to enable automatic travel of the work vehicle along the target path. The automatic travel control unit, when the work vehicle is positioned on a work path in the vicinity of a boundary with a turning path, sets the control target position on an extension of the work path. The automatic travel control unit, when the work vehicle is positioned on a turning path in the vicinity of a boundary with a work path, sets the control target position on the work path.

An autonomous agricultural vehicle that operates in accordance with a cleaning plan, a method for operating the vehicle, and a computer program related to operating the vehicle, wherein while the vehicle is operated, a load quantity representing an amount of material moved by the cleaning device is monitored at a plurality of individual times, and the cleaning plan of the autonomous agricultural vehicle is adjusted based on a variation in the monitored load quantity among the individual times.

This autonomous traveling control system is capable of generating, in a headland region which is in a farm field surrounded by peripheries formed from a plurality of edges and which is formed between the peripheries and a work region in which a work vehicle works while traveling autonomously, a headland traveling auxiliary route along which the work vehicle travels autonomously. The autonomous traveling control system selects, from among the plurality of edges, a selective edge for generating the headland traveling auxiliary route, on the basis of the distance between the edges and the vehicle position of the work vehicle and of the angles formed between the edges and the vehicle orientation of the work vehicle.

An agricultural machine includes one or more illuminators to illuminate surroundings of the agricultural machine in a traveling direction thereof, and a controller to control self-driving of the agricultural machine while keeping at least one of the one or more illuminators deactivated at nighttime.

A management terminal, which manages one of a tractor, a rice transplanter, and a combine harvester, as a plurality of types of work machines that perform a plurality of types of work, respectively, on a field, is provided with a storage portion which stores a management application for managing the plurality of types of work machines, a control device which activates the management application, and a display portion. When the control device activates the management application, the control device displays, on the display portion, a plurality of app activation icons corresponding to the plurality of types of work machines, respectively, in such a way that the plurality of app activation icons are selectively operable. Also, the control device activates, in response to selective operation of any one of the plurality of app activation icons, an individual application for operating the work machine corresponding to the selectively operated app activation icon.

The field engagement unit additionally includes one or more propulsion units which provide omnidirectional control of the field engagement unit. The field engagement unit additionally includes one or more work tool assemblies. The one or more work tool assemblies are actuatable along the one or more work tool rail assemblies. The farming system additionally includes a local controller. The local controller includes one or more processors configured to execute a set of program instructions stored in memory. The program instructions are configured to cause the one or more processors to control one or more components of the field engagement unit.

The present invention relates to mobile machinery such as an agricultural tractor comprising a three-point hitch for the connection and use of working implements cultivating or excavating the earth and other duties involved in the industry of farming or grading excavation. The disclosed invention modifies and improves the conventional three-point hitch in use today. The disclosed invention modifies the three-point hitch by adding extending and retracting implement-actuators attachable to the existing bottom-lift-arms, therefore supplanting, but still using the existing bottom-lift-arms on the three-point hitch. The implement-actuators assist the implement in correcting the implements centerline when the tractor centerline is off a predetermined centerline path. In addition, the extending of the implement-actuators proportionally, inversely and simultaneously can correct the pivot point of the implement to match the pivot point of the tractor while the tractor performs turns during the working use of the implement.

An agricultural machine includes a traveling vehicle body, a detector to detect objects in an area surrounding the traveling vehicle body, a detection adjuster to adjust a detection direction of the detector, a position sensor to detect a position of the traveling vehicle body, and an information acquirer to acquire information relating to an entrance/exit of an agricultural field. The detection adjuster is operable to perform a first adjustment of orienting the detection direction toward an end point of the entrance/exit when the traveling vehicle body is traveling toward the entrance/exit and a distance from the position of the traveling vehicle body to the entrance/exit included in the information is a predetermined value or less, and a second adjustment of orienting the detection direction toward the end point of the entrance/exit or a space forward of the end point in a traveling direction when the traveling vehicle body is traveling on the entrance/exit.

An agricultural support system includes a first communication device located in or on a tractor to transmit information, and a second communication device located in or on a transport vehicle to acquire the information transmitted from the first communication device. The transport vehicle is capable of transporting the tractor. The agricultural support system further includes a position sensor in or on the working machine to detect a position of the working machine. The first communication device is operable to transmit the position detected by the position sensor to the second communication device as the information. The second communication device is operable to receive the position transmitted from the first communication device.

A path controller for guiding an autonomous vehicle along a desired path may include an input module that may receive input signals such as, a normal error signal that indicates an off-path deviation of the autonomous vehicle relative to a desired path, a heading signal, and a curvature signal associated with the autonomous vehicle. The path controller may also include a curvature rate module that calculates a curvature rate output signal to guide the autonomous vehicle along the desired path and a communication module that communicates the curvature rate output signal to a steering control system.
