Abstract
A work vehicle includes a power source, a travel device that includes a clutch capable of adjusting a degree of engagement between the power source and a transmission, and travels on a basis of power transmitted from the power source, working equipment, a drive device that operates the working equipment on a basis of power transmitted from the power source, and a control device that outputs a control command for controlling the degree of engagement of the clutch on a basis of a state of the working equipment.
Claims5
A work vehicle comprising:
- a power source;
- a travel device that includes a clutch capable of adjusting a degree of engagement between the power source and a transmission, and travels on a basis of power transmitted from the power source;
- working equipment;
- a drive device that operates the working equipment on a basis of power transmitted from the power source;
- and
- a control device that outputs a control command for controlling the degree of engagement of the clutch on a basis of a state of the working equipment,
- wherein the state of the working equipment includes an operation speed of the working equipment, and
- wherein the control device outputs the control command such that the degree of engagement decreases when a clutch control start condition is satisfied in which a state in which the operation speed of the working equipment is lower than a speed determination value continues for a specified time or longer.

A control method for a work vehicle comprising:
- in the work vehicle including working equipment, outputting a control command for performing engagement of a clutch disposed between a power source and a transmission and capable of adjusting a degree of engagement such that power generated in the power source is transmitted to a travel device including the clutch;
- and
- outputting a control command for decreasing the degree of engagement of the clutch on a basis of a state of the working equipment,
- wherein the state of the working equipment includes an operation speed of the working equipment, and
- wherein the control command is output such that the degree of engagement decreases when a clutch control start condition is satisfied in which a state in which the operation speed of the working equipment is lower than a speed determination value continues for a specified time or longer.
