More Information
Summary:A method of controlling a machine power source includes receiving a request indicative of desired machine implement movement. The desired movement will require a corresponding change in loading on a hydraulic pump. The method also includes determining a steady state torque required for the request, and determining a transient torque required for the request. The transient torque is based on a desired rate of implement movement associated with the request. The method further includes generating a power source fueling signal corresponding to a total torque required for the change in loading on the pump, and providing fuel to the power source based on the fueling signal prior to transmission of the change in loading on the pump to the power source.
