Abstract: A work vehicle includes a work implement, a valve adjusting a flow rate of a hydraulic oil operating the work implement, an electromagnetic proportional control valve generating a pilot pressure guided to the valve, a controller outputting a current to the electromagnetic proportional control valve, and a sensor for detecting an operation of the work implement. The controller increases stepwise a current value of a current output to the electromagnetic proportional control valve by repeating processing for temporarily lowering a current value of the current output to the electromagnetic proportional control valve and thereafter outputting to the electromagnetic proportional control valve, a current having a current value greater than the current value before lowering. The controller calibrates data for predicting an operation speed of the work implement based on a result of detection by the sensor at the time when the current value is increased stepwise.
