Abstract
A work vehicle includes a bucket which can perform a tilting operation with a hydraulic oil, a valve adjusting a flow rate of the hydraulic oil having the bucket perform the tilting operation, 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 first sensor for detecting the tilting operation. The controller detects a horizontal state of the bucket based on an output from the first sensor. The controller adjusts a value for the current output to the electromagnetic proportional control valve after the horizontal state of the bucket is detected, and starts calibration of data for predicting an operation speed of the bucket in the tilting operation.
