An agricultural work assistance system includes a display to display a map representing an agricultural field, and a controller configured or programmed to define or function as an area setter to set a first area and a second area located inward of the first area in the map displayed by the display, and a route creator to create, in at least one of the first area or the second area, a travel route along which an agricultural machine is to travel. The route creator is configured or programmed to set at least a portion of the travel route as an automatic steering route on which the agricultural machine is to be automatically steered and a travel speed of the agricultural machine is to be changed manually.

Agricultural work assistance system, agricultural work assistance apparatus, and agricultural machine

An agricultural assistance system includes a route creator to create, on a map representing an agricultural field, a travel route along which an agricultural machine travels, an input to receive input of a turn mode which is one of turn modes differing in terms of how a traveling device of the agricultural machine is driven, a position detector to detect a position of the agricultural machine, an automatic operation controller to perform automatic operation in which the automatic operation controller automatically causes the agricultural machine to travel and automatically steers the agricultural machine, and a turn mode changer to, during automatic operation of the agricultural machine, allow the input to receive input of another turn mode to change the turn mode, and output, to the automatic operation controller, a change command to cause the agricultural machine to turn in the other turn mode inputted via the input.

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 Wof a work deviceis larger than a lateral width Wof 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 Dbetween a front end position of a work vehicleand a reference position SP at which the work deviceis switched from a working state to a non-working state.

Travel control system

A working machine includes a machine body, a lifting device to link a working device to the machine body, the lifting device being capable of moving up and down with the working device between a grounding state in which the working device is in contact with a ground and an ungrounding state in which the working device is out of contact with the ground, and an automatic travel controller to cause the machine body to perform automatic travel according to a planned travel route. The automatic travel controller includes a lifting controller to control the lifting device to move up with the working device from the grounding state to the ungrounding state, and cause the machine body to turn or travel rearward after the lifting controller controls the lifting device to move up with the working device from the grounding state to the ungrounding state.

Working machine

An agricultural machine includes a vehicle body, an obstacle detector to detect obstacles, an autonomous travel controller to perform autonomous travel of the vehicle body, the autonomous travel controller being configured or programmed to, when performing the autonomous travel, stop the vehicle body based on detection information about an obstacle detected by the obstacle detector, and a mode switch to switch a mode during the autonomous travel in an agricultural field between an effective mode in which the stopping of the vehicle body based on the detection information is allowed and an ineffective mode in which the stopping of the vehicle body based on the detection information is not allowed.

Agricultural machine

A working machine includes a machine body capable of traveling, a position detector to detect a position of the machine body, and a controller to control the machine body based on the position of the machine body detected by the position detector and a planned travel route. The planned travel route includes a straight section on which the machine body travels straight, and the controller includes a threshold setter to set a threshold according to work, and causes the machine body to perform a recovery movement to make a deviation between the position of the machine body detected by the position detector and the planned travel route less than the threshold when the machine body is at a start point of the straight section or is about to enter the start point of the straight section.

In an agricultural machine, a route creator creates a planned traveling route for a traveling vehicle body in a work area where a working device works using a material. An area setter sets, outside the work area, a replenishment area to replenish the material. A charge amount acquirer acquires a charge amount of the material. A remaining amount calculator calculates a remaining amount of the material based on the charge amount acquired and a material consumption of the material consumed by the work. A position setter sets a replenishment position to replenish the material in the replenishment area set by the area setter based on the remaining amount calculated by the remaining amount calculator. A position changer changes the replenishment position when a change reception switch receives change of the replenishment position. A display displays the changed replenishment position.
