Title:
WORK VEHICLE, AND METHOD OF CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2015/093162
Kind Code:
A1
Abstract:
A control unit includes a neutral control determination unit, a forward/reverse clutch control unit, and a command torque determination unit. The neutral control determination unit determines implementation of pseudo-neutral control when a pseudo-neutral control determination condition is satisfied. The pseudo-neutral control determination condition includes a forward/reverse operation member being in neutral position. The forward/reverse clutch control unit, during pseudo-neutral control, maintains a forward clutch or a reverse clutch in connected state. The command torque determination unit, during pseudo-neutral control, determines a command torque for a motor so as to achieve a neutral state in which an output torque from a power transmission device to a travel device is suppressed to a predetermined value regardless of driving force from an engine.
