Abstract

A working vehicle includes a traveling vehicle body, a linking device capable of linking a working device to the traveling vehicle body, a sensor provided on the working device to monitor at least a surrounding area of the working device provided on the working device, and a controller to perform control relating to automatic operation of the traveling vehicle body based on a planned travel route and monitored information obtained by the sensor. The controller is configured or programmed to include an automatic operation controller to determine the automatic operation to be performed if the monitored information contains no obstacles and to determine the automatic operation not to be performed if the monitored information contains an obstacle.

the controller is configured or programmed to define and function as a work manager to extract one or more worked conditions resulting from work done by the working device based on the monitored information obtained by the first sensor;

the automatic operation controller is configured or programmed to, after initiation of the automatic operation:

cause the working device to perform the work when causing the traveling vehicle body to travel along a straight route included in the planned travel route;

not cause the working device to perform the work and to determine whether or not the object in the monitored area is an obstacle based on the monitored information when causing the traveling vehicle body to travel along a turning route included in the planned travel route; and

the work manager is configured or programmed to:

when the traveling vehicle body is traveling along the straight route, extract the one or more worked conditions based on the monitored information; and

when the traveling vehicle body is traveling along the turning route, stop extracting the one or more worked conditions based on the monitored information.

2. The working vehicle according to claim 1 , wherein

the linking device includes a raising/lowering device to raise and lower the working device; and

the automatic operation controller is configured or programmed to, after initiation of the automatic operation, analyze the monitored information obtained when the working device is held in a raised position by the raising/lowering device to recognize the object in the monitored area and determine whether or not the object is an obstacle, and stop the automatic operation if the object is an obstacle.

3. A working vehicle comprising:

a traveling vehicle body;

a linking device provided on the traveling vehicle body and capable of linking a working device;

a first sensor provided on the working device;

a switch; and

a controller configured or programmed to define and function as:

an automatic operation controller to perform control relating to automatic operation of the traveling vehicle body based on a planned travel route and based on monitored information obtained by the first sensor with the working device linked to the traveling vehicle body; and

a work manager to extract one or more worked conditions resulting from work done by the working device and cause a display to display the one or more worked conditions based on the monitored information; wherein

the switch is to be operated to switch between causing the automatic operation controller to perform the control relating to the automatic operation based on the monitored information and causing the work manager to extract the one or more worked conditions resulting from work done by the working device based on the monitored information.

4. The working vehicle according to claim 3 , wherein the work manager is configured or programmed to extract the one or more worked conditions after initiation of the automatic operation.

5. The working vehicle according to claim 3 , wherein

the linking device includes a raising/lowering device to raise and lower the working device;

the automatic operation controller is configured or programmed to:

analyze the monitored information with the traveling vehicle body in a stopped state to recognize an object in a monitored area of the first sensor and determine whether or not the object is an obstacle, start the automatic operation if the object is not an obstacle, and not start the automatic operation if the object is an obstacle; and

after initiation of the automatic operation, analyze the monitored information obtained when the working device is held in a raised position by the raising/lowering device to recognize the object in the monitored area and determine whether or not the object is an obstacle, stop the automatic operation if the object is an obstacle, and continue the automatic operation if the object is not an obstacle; and

the work manager is configured or programmed to extract the one or more worked conditions based on the monitored information obtained in a period from the initiation of the automatic operation to raising of the working device, and extract the one or more worked conditions based on the monitored information obtained during work done by the working device after the initiation of the automatic operation.

6. The working vehicle according to claim 1 , further comprising a second sensor provided on the traveling vehicle body, a viewing direction of the second sensor being the same as a viewing direction of the first sensor.

7. A working vehicle comprising:

a traveling vehicle body;

a linking device provided on the traveling vehicle body and capable of linking a working device;

a first sensor provided on the working device; and

a controller configured or programmed to define and function as:

an automatic operation controller to perform control relating to automatic operation of the traveling vehicle body based on a planned travel route and based on monitored information obtained by the first sensor with the working device linked to the traveling vehicle body; and

a work manager to extract one or more worked conditions resulting from work done by the working device and cause a display to display the one or more worked conditions based on the monitored information; wherein

the automatic operation controller is configured or programmed to:

when no work is being performed by the working device before or after initiation of the automatic operation, perform control relating to the automatic operation based on the planned travel route and the monitored information; and

when work is being performed by the working device and the traveling vehicle body is traveling after the initiation of the automatic operation, perform control relating to the automatic operation based on the planned travel route; and

the work manager is configured or programmed to extract the one or more worked conditions based on the monitored information when work is being performed by the working device and the traveling vehicle body is traveling after the initiation of the automatic operation.

8. The working vehicle according to claim 7 , wherein the automatic operation controller is configured or programmed to analyze the monitored information to recognize an object in a monitored area of the first sensor and determine whether or not the object is an obstacle, perform the automatic operation if the object is not an obstacle, and not perform the automatic operation if the object is an obstacle.

9. The working vehicle according to claim 8 , wherein

the linking device includes a raising/lowering device to raise and lower the working device;
