Claim:
1. A work vehicle comprising: an engine; a work implement pump driven by the engine; a work implement driven by hydraulic fluid discharged from the work implement pump; a travelling apparatus driven by the engine; a power transmission device including an input shaft for inputting driving power from the engine, an output shaft for outputting driving power transmitted to the travelling apparatus, and a motor; a vehicle speed detecting unit configured to detect a vehicle speed; a work implement pump pressure detecting unit configured to detect a work implement pump pressure of the work implement pump; a work implement operating member for operating the work implement; a work implement operation detecting unit configured to detect an operation amount of the work implement operating member; an accelerator operating member; an accelerator operation detecting unit configured to detect an operation amount of the accelerator operating member; and a control unit configured to control the power transmission device; the power transmission device being configured so that a rotation speed ratio of the output shaft with respect to the input shaft is changed by changing the rotation speed of the motor; the control unit including in a first case
