Abstract
A method for controlling a work vehicle including a pump driven by a power source, a cylinder controlling a displacement of the pump based on a pressure of supplied hydraulic fluid and switching a discharge direction of the hydraulic fluid from the pump based on a supply direction of the supplied hydraulic fluid, and a valve switching the supply direction of the hydraulic fluid to the cylinder, the method includes: detecting a vehicle speed of the work vehicle; receiving a command signal from a second operation device operated to switch between forward travel and reverse travel of the work vehicle; determining whether a shuttle shift operation is performed based on the vehicle speed and the command signal; and controlling the valve based on an operation amount of a first operation device operated by an operator to control the power source when the shuttle shift operation is determined to be performed.
