Kind Code:
A
Abstract:
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
