Patent ID: 8483916

Claim:
A hydraulic control system, comprising: a pump configured to pressurize fluid; a plurality of actuators configured to receive the pressurized fluid; a plurality of valve arrangements configured to meter pressurized fluid from the pump into the plurality of actuators; at least one operator input device configured to generate signals indicative of desired velocities of the plurality of actuators; and a controller in communication with the plurality of valves and the at least one operator input device, the controller being configured to: receive a pump torque limit; determine a maximum pump flow capacity; determine desired flow rates for each of the plurality of valve arrangements based on the signals from the at least one operator input device; make a first reduction of the desired flow rates based on the maximum pump flow capacity; make a second reduction of the desired flow rates based on the pump torque limit; and command the plurality of valve arrangements to meter the desired flow rates after the second reduction.
