Claim Text:
1. A work vehicle, comprising: an engine; a hydraulic pump driven by the engine; a work implement driven by hydraulic fluid discharged from the hydraulic pump; a work implement operating member for operating the work implement; a travel device driven by the engine; a power-transmission device configured to transmit driving power from the engine to the travel device; a vehicle speed detecting unit for detecting a vehicle speed; an accelerator operating member; an accelerator operation detecting unit for detecting an operation amount of the accelerator operating member; and a control unit configured to control the power-transmission device; the power-transmission device including the control unit including the target-input-torque determination unit determining an upper limit of the target input torque from an upper limit target input torque line and the engine rotation speed; and the upper limit target input torque line defining a value smaller than the target output torque of the engine determined from the engine required horsepower and the engine rotation speed, as the upper limit of the target input torque.
