Abstract
The work vehicleincludes a main controllerthat controls a travel driving force and a work driving force. The main controllerincludes a travel remaining time calculating unitthat calculates a remaining time until a target rise/run distance is reached as a travel remaining time t, a work remaining time calculating unitthat calculates a remaining time until a target arm angle is reached as a work remaining time t, a rise/run determining unitthat determines whether rise/run is being performed or not, a correction rate setting unitthat sets a travel correction rate ηthat adjusts a travel driving torque and a work correction rate ηthat adjusts a work driving torque based on the travel remaining time t, the work remaining time t, and the rise/run determination flag, and an engine torque distribution calculating unitthat calculates a travel driving torque command and a work driving torque command based on the travel correction rate ηand the work correction rate η.
