Working vehicle
A working vehicle includes a traveling vehicle body, and an automatic driving controller to perform first automatic driving in which different operations relating to the traveling vehicle body are performed automatically and second automatic driving in which at least one of the different operations is set to be performed manually and another one or more of the different operations other than the at least one of the different operations set to be performed manually continue to be performed automatically.
1. A working vehicle comprising:
a traveling vehicle body;
an automatic driving controller to perform first automatic driving in which a plurality of types of operations relating to the traveling vehicle body are performed automatically and second automatic driving in which at least one of the plurality of types of operations is set to be performed manually and the other one or more of the plurality of types of operations other than the at least one of the plurality of types of operations set to be performed manually continue to be performed automatically;
a steering unit including a steering wheel to steer the traveling vehicle body; and
a position detector to determine a vehicle body position which is a position of the traveling vehicle body; wherein
in the first automatic driving, the automatic driving controller is configured or programmed to automatically perform operation of the steering unit and one or more types of operations differing from the operation of the steering unit;
in the second automatic driving, the automatic driving controller is configured or programmed to set the operation of the steering unit to be performed manually and to continue to automatically perform the one or more types of operations differing from the operation of the steering unit; and
the automatic driving controller is configured or programmed to perform switching from the first automatic driving to the second automatic driving when the vehicle body position determined by the position detector is a predetermined position in an agricultural field and the steering wheel is operated manually.
2. The working vehicle according to claim 1 , wherein the automatic driving controller is configured or programmed to not perform the switching from the first automatic driving to the second automatic driving when the vehicle body position is not the predetermined position in the agricultural field.
3. The working vehicle according to claim 1 , wherein the automatic driving controller is configured or programmed to stop the automatic driving if an angle of steering by manual operation of the steering wheel is equal to or greater than a threshold.
4. The working vehicle according to claim 1 , further comprising a linkage to link a working device to the traveling vehicle body; wherein
the linkage includes a raising/lowering device to raise and lower the working device; and
the automatic driving controller is configured or programmed to perform operation of causing the raising/lowering device to raise or lower the working device as one of the one or more types of operations in the first automatic driving and the second automatic driving.
5. The working vehicle according to claim 1 , further comprising a transmission to change speed stages, the transmission being provided on the traveling vehicle body; wherein
the automatic driving controller is configured or programmed to perform operation of causing the transmission to change speed stages as one of the one or more types of operations in the first automatic driving and the second automatic driving.
6. The working vehicle according to claim 1 , further comprising a brake to perform braking, the brake being provided on the traveling vehicle body; wherein
the automatic driving controller is configured or programmed to perform operation of causing the brake to perform the braking as one of the one or more types of operations in the first automatic driving and the second automatic driving.
7. The working vehicle according to claim 1 , further comprising a switch to manually switch between the first automatic driving and the second automatic driving.
8. The working vehicle according to claim 1 , wherein the predetermined position in the agricultural field is a headland area of the agricultural field.
