INDUSTRIAL VEHICLE CONTROL DEVICE

A work vehicle control device includes: a rotation speed control unit that controls a rotation speed of an engine in correspondence to an accelerator pedal operation quantity indicating an extent to which an accelerator pedal is operated; a speed ratio detection unit that detects a speed ratio of a speed at an input shaft and a speed at an output shaft of a torque converter, which is disposed between the engine and wheels to transmit rotation of the engine to the wheels; a decision-making unit that makes a decision that a fuel efficiency deteriorating condition exists if the torque converter speed ratio detected via the speed ratio detection unit is less than a predetermined value or if the torque converter speed ratio detected via the speed ratio detection unit is equal to or greater than the predetermined value and a target engine rotation speed corresponding to an operation of the accelerator pedal is greater than a preset value; and an informing unit that informs results of the decision made by the decision-making unit.
