Abstract
A speed control method of a work vehicle includes receiving a setting stage set by a first operation member among a plurality of speed stages, obtaining a target moving direction of a work vehicle that is determined by a speed difference between a target rotation speed of a first hydraulic motor and a second hydraulic motor, determining an operating range of a first control parameter and an operating range of a second control parameter based on the setting stage when a second operation member is operated so that deviation amount between the target moving direction and the straight direction is within first range, and determining a boost stage among the plurality of speed stages that corresponds to target rotation speeds higher than the target rotation speeds of the setting stage when the second operation member is operated so that deviation amount is out of the first range.
