WORK VEHICLE AND WORK VEHICLE CONTROL METHOD

摘要

A work vehicle is provided with an engine, a hydraulic pump, a movement hydraulic motor, an acceleration operation member, and a control section. The hydraulic pump is driven by the engine. The movement hydraulic motor is driven by hydraulic fluid which is discharged from the hydraulic pump. The acceleration operation member is operated in order to set a target rotation speed for the engine. The control section is configured to perform traction control where the maximum traction force is reduced by limiting the displacement of the movement hydraulic motor to an upper limit displacement which is smaller than the maximum displacement. The control section increases the upper limit displacement of the movement hydraulic motor according to an increase in the operation amount of the acceleration operation member or the engine rotation speed in the traction control.
