CONTROL DEVICE OF WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a control device of a working vehicle which materializes both a large working quantity and a fuel saving.

SOLUTION: A controller 10 is equipped with tables 10a, 10b and 10e, 10f for determining maximum pump suction torque and engine output torque on the basis of an engine rotation speed, and with selecting parts 10c, 10g for switching between the determined maximum pump suction torque and engine output torque by whether at the time of working quantity mode or at the time of a fuel saving mode. A pump suction torque characteristic for the fuel saving mode is set as a small maximum pump suction torque TB at a high rotation speed region. An engine output characteristic for the fuel saving mode is set as a low engine output torque at high rotation speed region.
