| 摘要 | A power transmission device of a work vehicle includes a motor control unit that controls first and second motors to keep the transmission speed ratio at a maximum value when a vehicle speed is greater than a second vehicle speed where the transmission speed ratio reaches the maximum value obtainable by the power transmission device, and less than a third vehicle speed where a rotation speed of the second motor reaches a predetermined limit value. A controller increases a rotation speed of an engine from a second rotation speed of the engine when the vehicle speed is greater than the second vehicle speed and less than a third vehicle speed, and increases the rotation speed of the engine from a third rotation speed of the engine when the vehicle speed is greater than the third vehicle speed. | ||||||
