Abstract: A travel route generating device for a work vehicle includes a cell memory to store cell information with respect to cells obtained by dividing a topographical map of a work field in which the work vehicle works. A travel probability memory is to store a travel probability with respect to each of the cells. The travel probability includes a left-turn travel probability, a straight travel probability, and a right-turn travel probability in each of the cells. Circuitry is configured to determine a travel direction in each of the cells based on the travel probability of each of the cells. The work vehicle is configured to travel through each of the cells in the travel direction. The circuitry is configured to change the travel probability with respect to affected cells affected by moving the work vehicle through each of the cells.

Abstract: A control system for a work vehicle that performs auto-steer driving includes a storage to store a target path for the work vehicle, and a controller configured or programmed to control steering of the work vehicle so that the work vehicle travels along the target path based on a position of the work vehicle identified by a position identifier and the target path stored in the storage. The target path includes parallel main paths and one or more turning paths interconnecting the plurality of main paths. When the work vehicle is turning along one of the turning paths via automatic steering, if the position of the work vehicle becomes deviated from the turning path by more than a reference distance, the controller is configured or programmed to cause an alarm generator to output an alarm.

Abstract: 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.

Abstract: A travel route generation apparatus includes a work field data input interface, a handwriting input interface, a memory, and circuitry. Work field data are to be input via the work field data input interface. The work field data includes data regarding a shape of a work field in which a work vehicle is to work. A handwriting locus is to be input via the handwriting input interface. The memory is to store travel route patterns. The circuitry is configured to select a designated travel route pattern from travel route patterns based on the handwriting locus and to generate, based on the designated travel route pattern and the work field data, a travel route along which the work vehicle is to travel in the work field.

Abstract: 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.
