Abstract: A travel route generation device includes circuitry configured to calculate positions of a starting point, an end point, and intermediate points from a start vehicle position, an end vehicle position, and intermediate vehicle positions, respectively, based on a distance from a contour point to a reference point. The circuitry is configured to define the shape of the target work region by calculating a line connecting the starting point, the intermediate points, and the end point, the line defining the shape of the target work region. The circuitry is configured to generate a travel route along which the work vehicle is to travel in the target work region.

Abstract: A harvester includes: a crop tank that stores a crop harvested by a harvesting device; a weight detection unit that detects a storage weight, which is a value indicating the weight of the crop stored in the crop tank; a maximum weight calculation unit that calculates a maximum weight, which is a value indicating the weight of the crop at the maximum storage amount of the crop tank; a unit harvest weight calculation unit calculates a unit harvest weight that indicates the weight of the crop harvested per unit of harvest-travel distance; and a maximum travel distance calculation unit that calculates a maximum travel distance, which is the maximum distance that can be traveled during traveling harvesting before the amount of the crop stored in the crop tank reaches the maximum storage amount, based on the storage weight, the maximum weight, and the unit harvest weight.

Abstract: A work vehicle includes a touch-panel display, at least one first physical button, and the circuitry. The touch-panel display is to display at least one first touch button, at least one first function, and work information. The at least one function is displayed in the at least one first touch button to which the at least one first function is assigned. The work information includes a state of work which the work vehicle performs. The at least one first physical button is provided outside the touch-panel display. The at least one first function is assigned to the at least one first physical button. The circuitry is configured to change the at least one first function assigned to the at least one first touch button and the at least one first physical button in accordance with the work information.

Abstract: A sensor management device includes first circuitry and second circuitry. The first circuitry is configured to output an instruction to position a target obstacle on a detectable region of at least one obstacle sensor provided on a work vehicle to detect an obstacle. The second circuitry is configured to determine, based on an output of the at least one obstacle sensor with respect to the target obstacle, whether the at least one obstacle sensor works normally.

Abstract: A travel control apparatus for a work vehicle includes a display and circuitry. The display is to display a position of the work vehicle. The circuitry is configured to display in the display a guide index via which the work vehicle is manually guided to an automatic-travel permitted area in which the work vehicle is configured to automatically travel, and to determine whether or not the work vehicle is located in the automatic-travel permitted area.

Abstract: A work vehicle management system includes a memory, first circuitry, second circuitry, third circuitry, and fourth circuitry. The memory is to store at least one halt record with respect to a halt status at a timing when a work vehicle is halted while traveling along a travel route in a work field. The first circuitry is configured to record the at least one halt record in the memory. The second circuitry is configured to extract the at least one halt record from the memory to display in a display the at least one halt record from which a resuming basis record is to be selected. The third circuitry is configured to generate resuming information based on the resuming basis record. The fourth circuitry is configured to control the work vehicle based on the resuming information to resume from the halt status.

Abstract: A division map creation system includes circuitry and a memory. The circuitry is configured to acquire work field information including a shape of a work field and a position of the work field and to acquire travel routes based on the work field information. Each of work vehicles is configured to travel along each of the travel routes in the work field. The circuitry is configured to divide the work field into a plurality of sections in order to create division maps based on a travel direction in which each of the work vehicles travels along each of the travel routes and based on a work width within which each of the work vehicles works while travelling in the work field. The memory is to store the division maps such that each of the division maps corresponds to each of the work vehicles.
