One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

A work assistance system is a system used together with a work machine, wherein an estimation unit and an output unit are provided. The work machine has an engine as the power source thereof, and travels in a field. On the basis of at least the magnitude of the load of the engine, the estimation unit estimates whether there is an occurrence of a target event that accompanies fluctuations in the load. The output unit outputs output data corresponding to the estimation results from the estimation unit.

Methods, apparatus, and articles of manufacture to generate a turn path for a vehicle are disclosed. An example apparatus disclosed herein includes input interface circuitry to obtain a guidance path for a vehicle, turn identification circuitry to identify a turn in the guidance path, and turn pattern selection circuitry to select, from a plurality of predetermined turn patterns, a turn pattern for the turn, wherein the turn pattern satisfies a condition.

On a straight route, a traveling processor sets a work instrument to a working posture, and causes the work vehicle to travel at a first traveling speed. In a turn route connecting to a straight route, the traveling processor sets the work instrument to the non-working posture, and caused the work vehicle to travel at a second driving speed lower than the first traveling speed. In a partial route from an end position of a turn route to a predetermined position, the traveling processor causes the work instrument to change from the non-working posture to the working posture, and causes the work vehicle to travel at a third traveling speed lower than the first traveling speed.

A travel control system includes a permission unit that permits outermost periphery automatic traveling if predetermined permission conditions are satisfied. The permission conditions include a first condition and a second condition. The first condition is that a reference value corresponding to a working width W1 of a work device 30 is larger than a lateral width W2 of the work device. The second condition is that the reference value is larger than a threshold value determined by a threshold value determination unit. The threshold value determination unit determines the threshold value based on a reference distance D1 between a front end position of a work vehicle 1 and a reference position SP at which the work device 30 is switched from a working state to a non-working state.

Methods and apparatus for assessing coordinate data are disclosed. An example apparatus includes a processor to receive coordinate data relating to a desired path and task of a vehicle. The processor of the example apparatus to determine if the coordinate data satisfies a threshold. The processor of the example apparatus to determine if the coordinate data is compatible with a positioning system of the vehicle. The processor of the example apparatus to authorize operation of the vehicle to traverse the desired path based on the coordinate data.

An objective of the present invention is to make it possible to obtain, with a simple operation, a target route for autonomous travel suited to, for example, a user's sense of values. A target route generation system for a work vehicle includes a storage part 30A that stores basic data necessary for generating a target route P for autonomous travel, a priority item selection part 34 that prompts selection of a priority item with regard to generation of the target route P, and a target route generation part 30D that generates the target route P based on the basic data and the selected priority item.

A management terminal of a worker that manages a combine harvester as a work vehicle capable of performing an automatic travel performs the following operation: a controller, by the management terminal, starts an application that manages the combine harvester, and then a display control unit, by the application, selectably displays, on a display unit of the management terminal, a plurality of work items related to work performed by the combine harvester in a farm field.

A method and system for automatically removing undesirable vegetation is provided. The method includes receiving by a first vehicle, data describing a specified geographical area for scanning. The specified geographical area is divided into a plurality of sectors and a second vehicle is directed to a first sector of the plurality of sectors. First geographical coordinates associated with areas of undesirable vegetation growth located within the first sector are receiving from the second vehicle and an optimal travel path from a current location of the first vehicle to the areas of undesirable vegetation growth located within first sector are determined based on analysis of the first geographical coordinates. The first vehicle is directed to the areas of undesirable vegetation growth via the optimal travel path and a process for eliminating the areas of undesirable vegetation growth is executed.

The purpose of the present invention is to improve visibility of a status display unit while simplifying the installation of the status display unit and preventing damage to the status display unit. The present invention comprises: a work vehicle body capable of traveling automatically; a status detection unit that detects the status of the work vehicle body; and status display units that show a status display according to the status of the work vehicle body detected by the status detection unit. At least one pair of status display units are arranged diagonally across the work vehicle body in plan view.
