Abstract: A work vehicle includes a display, communication circuitry, and circuitry. The display is to display information. The communication circuitry is configured to communicate with a cooperative work vehicle that is configured to work cooperatively with the work vehicle. The circuitry is configured to acquire from the cooperative work vehicle through the communication circuitry traveling work parameters manually set via operation tools provided on an operation panel in the cooperative work vehicle. The circuitry is configured to display in the display a setting confirmation screen based on the traveling work parameters acquired through the communication circuitry, the setting confirmation screen showing the operation panel in the cooperative work vehicle.

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 work-vehicle position measurement system includes a reference station and a work vehicle. The reference station is provided at a reference position to measure a measured position of the reference position by receiving a radio wave from a satellite and to transmit reference information including the measured position. The work vehicle includes circuitry configured to obtain a calculated position of the work vehicle based on satellite information from the satellite and the reference information transmitted from the reference station, to control the work vehicle to travel along a predetermined travel route in a work field based on the calculated position of the work vehicle, and to manage map data of the work field to correspond to the reference information of the reference position.

Abstract: A travel route generation device includes a memory, an input interface, and circuitry. The memory is to store field data including shape information on a shape of a field in which a work vehicle is to work. A field operation parameter is input via the input interface. The field operation parameter includes headland information on a headland in the field. The circuitry is configured to generate, based on the field data and the field operation parameter, a travel route along which the work vehicle is to travel in the field. The circuitry is configured to estimate a work status of the work vehicle in the field. The circuitry is configured to display the shape of the field, the travel route, and the work status in a display.

Abstract: A work vehicle includes a memory, a sensor, circuitry, and a display. The memory is to store a target travel route in a work field. The sensor is to detect an actual travel track of the work vehicle to find a traveled portion of the target travel route, along which the work vehicle has traveled. The circuitry is configured to calculate an index value indicating a degree of a deviation of the actual travel track from the target travel route. The display is to display the traveled portion such that a display pattern to display the traveled portion is changed according to the index value.

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 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: An access point device for a work machine is configured to connect a work machine and a mobile terminal via wireless communication. The access point includes a memory, a controller, and a communicator. The memory is to store data of the work machine. The controller is to set a request as a communication identifier to be received by a mobile terminal. The mobile terminal is configured to obtain the data stored in the memory in accordance with the request. The communicator is to transmit the communication identifier to the mobile terminal and to transmit the data stored in the memory to the mobile terminal.
