Zusammenfassung:	To accurately acquire target output even when actual differential pressure become separated from target differential pressure, in a work vehicle that includes a static hydraulic type transmission.SOLUTION: A controller determines a correction factor from an operation rate of an accelerator operation member and at least one hydraulic pressure of a first circuit and a second circuit. The controller determines a target vehicle speed from the operation rate of the accelerator operation member. The controller determines a target capacity for a traveling pump and/or a target capacity for a traveling motor from the target vehicle speed and the correction factor.SELECTED DRAWING: Figure 16 【課題】静油圧式トランスミッションを備える作業車両において、実差圧が目標差圧から乖離していても、狙いとする出力を精度良く得る。【解決手段】コントローラは、アクセル操作部材の操作量と、第１回路と第２回路との少なくとも一方の油圧とから補正率を決定する。コントローラは、アクセル操作部材の操作量から目標車速を決定する。コントローラは、目標車速と補正率とから、走行用ポンプの目標容量、及び／又は、走行用モータの目標容量を決定する。【選択図】図１６
