The invention provides a control system for a working vehicle, which can
realize higher work performance and better fuel economy in a compatible
way. A controller 10 includes table 10a, 10b and tables 10e, 10f for
deciding maximum pump absorption torques and engine output torques based
on an engine revolution speed, and selectors 10c, 10g for switching over
the decided maximum pump absorption torques and engine output torques
depending on a work performance mode or a fuel economy mode is selected.
A pump absorption torque characteristic for the fuel economy mode is set
so as to provide a relative small maximum pump absorption torques TB in a
high revolution range, and an engine output characteristic for the fuel
economy mode is set so as to provide a relatively small engine output
torque in the high revolution range.
