Abstract:
An apparatus for controlling the torque associated with a power train of a machine having a work implement, the power train including an engine, comprising:a plurality of position sensors that sense a position associated with the work implement and responsively produce respective position signals;an engine speed sensor that senses the speed of the engine and responsively produces an engine speed signal;means for producing a signal indicative of a desired speed of the engine; anda controller that receives the position signals, determines an angular position of the work implement, receives the actual and desired engine speed signals, modifies the desired engine speed in response to the angular position of the work implement and a software look-up table that stores a plurality of scaling values that correspond to a plurality of angular values associated with the work implement, wherein the controller selects at least one of the plurality of scaling values in response to the angular position of the work implement, multiplies the selected scaling value by the desired engine speed, and regulates the speed of the engine based on the modified desired engine speed to control the power train torque.
