Apparatus for controlling the torque on a power train and method of operating the same

摘要

An apparatus and method for controlling the torque on the power train of a machine is disclosed. The power train includes an engine and a torque converter. The machine includes a work implement that is moveable in response to the actuation of a plurality of hydraulic cylinders. An electronic controller determines an optimal engine speed based on the actual engine speed, torque converter output speed, and the fluid pressure associated with the hydraulic cylinders. The optimal engine speed is used to govern the speed of the engine to control the power train torque.
