WORK VEHICLE AND METHOD FOR CONTROLLING WORK VEHICLE

A power transmission includes first and second clutches for switching a transmission path for a driving force. A work vehicle includes a clutch controlling unit. As long as a speed ratio parameter transitions within a predetermined first range including a mode switching threshold after the speed ratio parameter reaches the mode switching threshold and then the transmission path is switched from a first mode to a second mode, the clutch controlling unit is configured to output a clutch command signal for disengaging the first clutch and output a clutch command signal for engaging the second clutch so as to keep setting the transmission path in the second mode even when the speed ratio parameter again reaches the mode switching threshold.
