An agricultural baler system includes: an agricultural baler including a bale chamber configured to form a bale from crop material, a crop conveyor configured to feed crop material into the bale chamber, a location sensor configured to output a location signal corresponding to a location of the agricultural baler, and a parameter sensor configured to output a parameter signal corresponding to a measured parameter; and a controller operably coupled to the travel sensor and the parameter sensor. The controller is configured to: determine an area based at least partially on a rake width of a rake and a defined length; determine a parameter distribution in a region of a field having the area based at least partially on the measured parameter and the location of the agricultural baler; and output a field map update signal to update a field map to indicate the determined parameter distribution.

A vehicle includes a rear steering system and a front differential hydraulic drive system. A first front drive control valve is operable to output a defined fluid flow in response to a steering command input. A second front drive control valve is operable to selectively divert a portion of the defined fluid flow output from the first front drive control valve. When the vehicle is operating in a pre-defined condition, a steering controller may control the second front drive control valve to divert a portion of the defined fluid flow from the first front drive control valve to define a reduced fluid flow, which is communicated to the front differential hydraulic drive system, to reduce a steering ratio of the front differential hydraulic drive system relative to the rear steering system, to desensitize steering provided by the front differential hydraulic drive system.

A method for identifying a trajectory between rows of a plantation using a radar interfaced with a processing means of an agricultural vehicle includes acquisition of an approximate distance between two consecutive rows of the plantation, acquisition of signals by the radar, processing of the signals to obtain a two-dimensional map of points corresponding to reflections picked up by the radar. The method further includes first linear interpolation to obtain a first interpolating line on the points of greatest intensity, second windowing of an elongated area of the two-dimensional map having an axis of development approximately parallel to the first interpolating line and at the approximate distance from the first interpolating line, second linear interpolation of a second interpolating line on points of greater intensity in the windowed area, and calculation of a trajectory parallel and intermediate between the first and second interpolating line.

In this obstacle detection system, if an obstacle has been detected by a front obstacle sensor or a rear obstacle sensor which has an obstacle detection range corresponding to the travel direction of the work vehicle, then a control unit displays the detected position of the obstacle on a display unit and performs collision avoidance control corresponding to the detection position of the obstacle; further, if an obstacle has been detected by a front obstacle sensor or a rear obstacle sensor which has an obstacle detection range not corresponding to the travel direction of the work vehicle, then the control unit displays the detected position of the obstacle on the display unit without performing collision avoidance control corresponding to the detection position of the obstacle.

Methods and systems for guiding movement of an agricultural system within a field including sensor data indicative of an environment of the agricultural system used to identify a material profile along which the agricultural system shall be guided, one or more properties of the material profile determined from the sensor data and in particular properties indicative of an irregularity in the material profile, determination of a correcting path segment for guiding movement of the agricultural system with respect to the material profile irregularity, and movement of the agricultural system controlled along the determined correcting path segment.

A combine harvester is a work vehicle capable of switching between a manual travel mode to travel based on operation of an operation tool including a steering wheel which is a turning operation tool and an autonomous traveling mode to travel based on a predetermined travel route, which includes a controller to function as an autonomous travel controller to control travel of the combine harvester through the autonomous travel mode based on the travel route. The combine harvester is switched from the autonomous travel mode to the manual travel mode without stopping the vehicle when the steering wheel is operated during the autonomous travel mode.

Technologies for guiding an agricultural vehicle through crop rows using a camera and signal processing to locate the crop row or centers of the crop row. The signal processing uses a filter to filter data from images captured by the camera and locates the row or the centers based on the filtered data. The filter is generated based on a signal processing transform and an initial image of the crop row captured by the camera. The filter is applied to subsequent images of the crop row captured by the camera. In some embodiments, the camera includes one lens. For example, monocular computer vision is used in some embodiments. Also, in some embodiments, a central processing unit generates the filter based on the transform and the initial image of the crop row and applies the generated filter to the subsequent images of the row.

An automatic traveling method includes causing a work vehicle to automatically travel according to a target route in a farm field, execute a spraying work of spraying a chemical liquid on crops, execute a stirring work of stirring the chemical liquid in a storage tank, and start the stirring work if a predetermined condition is satisfied before the work vehicle starts automatic travel.

A route generation method executes generating a plurality of work routes where a work vehicle travels straight in a first direction that is a travel direction of the work vehicle, in a work area where a crop is arranged, generating a movement route that is a route continuous with the work route and that includes a straight route where the work vehicle travels straight, in a headland area adjacent to the work area in the first direction, in non-work areas surrounding the work area, where the crop is not arranged, and generating a movement route that is a single route continuous with the movement route and that guides the work vehicle to each of the plurality of work routes.

A route determination method, a route determination system, and a route determination program are provided for determining a target route where a work vehicle can work while performing automatic traveling without damaging the topsoil of the work site.
