Claim 14:
15. The work vehicle according to claim 14, wherein
the controller has pump rotation speed data which defines a relationship between a standard rotation speed, which is the rotation speed of the engine when the absorption torque of the hydraulic pump reaches an upper limit on the pump absorption torque line, and the target rotation speed, and
the controller is further configured to
refer to the pump rotation speed data to determine the standard rotation speed from the target rotation speed under the variable matching control, and
control the rotation speed of the engine and the displacement of the hydraulic pump so that the output torque of the engine and the absorption torque of the hydraulic pump match each other at an intersection of the pump absorption torque line defined by the standard rotation speed, and the regulation line.
