Zusammenfassung:A speed control method for a work vehicle includes controlling a first hydraulic pump to supply hydraulic fluid to a first hydraulic motor to drive a first traveling device provided on a vehicle body of the work vehicle and detecting a first differential pressure of the first hydraulic motor. The method includes regulating at least one of a first pump pilot pressure applied to a first pump pilot port of the first hydraulic pump and a rotational speed of an engine to drive the first hydraulic pump such that a vehicle speed is controlled to maintain a predetermined target speed in response to an absolute value of the first differential pressure.
