Title:

WORK VEHICLE AND METHOD FOR CONTROLLING WORK VEHICLE

Document Type and Number:

WIPO Patent Application WO/2014/208615

Kind Code:

A1

Abstract:

A target-input-torque determination unit determines the target input torque on the basis of the transmission-request horsepower. The target input torque is a target value for the torque to be inputted to a power-transmission device. A target-output-torque determination unit determines the target output torque. The target output torque is a target value for the torque to be outputted by the power-transmission device. A command-torque determination unit uses torque-balance information to determine the command torque for the motor from the target input torque and the target output torque. The target-input-torque determination unit determines the upper value for the target input torque on the basis of an upper-limit-target-input-torque line and engine rotation speed. The upper-limit-target-input-torque line sets a value for the upper-limit value of the target input torque which is smaller than the target output torque of the engine determined using the engine-request horsepower and the engine rotation speed.
