WORK VEHICLE AND CONTROL METHOD FOR WORK VEHICLE

A work vehicle includes an engine, a hydrostatic transmission, and a controller. The hydrostatic transmission includes a traveling pump driven by the engine, a hydraulic circuit connected to the traveling pump, and a traveling motor connected to the traveling pump via the hydraulic circuit. The controller is configured to control the traveling motor and the traveling pump, determine a target flow rate of the traveling motor or the traveling pump, determine a correction amount of the target flow rate from a hydraulic pressure of the hydraulic circuit, and determine a target displacement of the traveling motor or the traveling pump from the target flow rate and the correction amount.
