摘要： [Problem] To provide a control method of a work vehicle, a work vehicle control program, a work vehicle control system, and a work system, by which appropriate determination of an override state becomes possible.
[Solution] A control method of a work vehicle (10) is a control method of a work vehicle (10) having an automatic steering mode for automatically steering a steered wheel (111) using a motor (421). The control method includes: in the automatic steering mode, controlling the motor (421); determining whether the work vehicle (10) is in an override state on the basis of a determination condition related to torque generated in the motor (421); and changing the determination condition.

摘要： [Problem] To provide an operation control method, an operation control system, and an operation control program capable of improving convenience of an operation unit for operating a work machine capable of automatic traveling.
[Solution] A vehicle control device 11 causes the work machine 10 to execute automatic travel when an automatic travel button 171 is operated by an operator in a state where a guidance screen D1 relating to automatic travel of a work machine 10 is displayed on an operation terminal 17, and does not cause the work machine 10 to execute automatic travel when the automatic travel button 171 is operated by the operator in a state where a non-guidance screen is displayed on the operation terminal 17.-

摘要： [Problem] The problem is to provide a route generation method, a route generation system, and a route generation program capable of causing a work vehicle to travel autonomously in an appropriate manner even in a case where the orientation of a target route including a plurality of straight routes is changed.
[Solution] The generation processing part 713 generates the target route R including a plurality of straight routes arranged at equal interval spacing W1, based on the reference line L1 which passes through point A and point B in the field F. In a case of changing the orientation of the target route R, the change processing part 714 maintains the interval spacing W1 of each of the plurality of straight routes.-

摘要： [Problem] To provide an operation control method, an operation control system, and an operation control program capable of improving work efficiency in a work machine including a machine body and a work implement attached to the machine body.
[Solution] The operation control method displays a horizontal control operation screen Dp51 relating to horizontal control that controls a tilt of a work implement with respect to a machine body, for a work machine including a machine body, and a work implement attached to the machine body. The setting related to the horizontal control is performed in accordance with an operation of a user on a control operation unit included in the horizontal control operation screen Dp51.-

摘要： [Problem] To provide an autonomous steering method, an autonomous steering system, and an autonomous steering program capable of improving the work efficiency of a work machine that can perform autonomous steering.
[Solution] A positioning control unit 161 performs positioning of a position of a work machine 10. A vehicle control device 11 causes the work machine 10 to execute autonomous steering on the basis of position information indicating the position of the work machine 10, for which the positioning is performed. A restriction processing unit 715 permits predetermined processing related to the autonomous steering when positional accuracy of the positioning is within an allowable range. A setting processing unit 714 sets the allowable range on the basis of a user operation or work information in the work machine 10.-

摘要： [Problem] To provide an autonomous travel method, an autonomous travel system, and an autonomous travel program capable of suppressing occurrence of acceleration/deceleration when a work vehicle travels a plurality of routes on which vehicle speeds are preset differently.
[Solution] On a straight advancing route r4 in which a straight advancing vehicle speed is preset following a turning route r3 in which a turning vehicle speed is preset, a traveling processor 111 causes a combine 1 to travel at a straight advancing vehicle speed if the distance L1 of the straight advancing route r4 is not less than a predetermined distance, and causes a combine 1 to travel at a turning vehicle speed if the distance L1 of the straight advancing route r4 is less than the predetermined distance.
