Title:
WORK VEHICLE AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/087832
Kind Code:
A1
Abstract:
A work vehicle is provided with: a bucket (107) that can be tilted by a working fluid; a valve for adjusting the flow rate of working fluid used to tilt the bucket (107); a solenoid proportional control valve that generates pilot pressure leading to the valve; a controller that outputs current to the solenoid proportional control valve; and a first sensor for detecting tilting. The controller detects that the bucket (107) has moved to a horizontal state on the basis of output from the first sensor. After detecting that the bucket (107) has moved to the horizontal state, the controller adjusts the current value of current output to the solenoid proportional control valve and begins data calibration for predicting the bucket operating speed resulting from tilting.
