Abstract
A forklift equipped with a variable displacement traveling hydraulic pump driven by an engine, a hydraulic motor that forms a closed circuit with the traveling hydraulic pump therebetween and is driven by hydraulic oil discharged from the traveling hydraulic pump, and driving wheels driven by the hydraulic motor, when an accelerator opening detected by an accelerator opening sensor is reduced, the accelerator opening detected by the accelerator opening sensor and a target maximum absorption torque of the traveling hydraulic pump are given to a table on which a setting value calculated in advance depending on the accelerator opening, and the target maximum absorption torque of the traveling hydraulic pump or a vehicle speed of the forklift is described to calculate the setting value, and the accelerator opening detected by the accelerator opening sensor is corrected using the obtained setting value to calculate a corrected accelerator opening.
