Winch Line Speed Control For A Track-Type Machine Having An Electric Drive Powertrain

Abstract:

A track-type machine is disclosed. The track-type machine may comprise an electric drive powertrain including an internal combustion engine, a winch assembly having a drum rotatably supporting a cable so that the cable is reeled in or reeled out at a winch line speed when the drum is rotating, and an implement controller configured to activate the winch assembly for reeling in and reeling out the cable. The track-type machine may further comprise a hydraulic circuit driven by the internal combustion engine and configured to actuate a rotation of the drum when the winch assembly is activated by the implement controller. In addition, the track-type machine may further comprise a control system configured to increase an engine speed of the internal combustion engine when the winch assembly is activated by the implement controller.
