Abstract: Method for adjusting a state-of-charge within an electrical energy storage device of a hybrid powertrain system includes monitoring a plurality of electrical energy storage device parameters and determining a discharge power capability of the electrical energy storage device based on the monitored plurality of electrical energy storage device parameters. If the discharge capability is less than a first threshold, a state-of charge adjustment mode is activated. The state-of-charge adjustment mode includes increasing a commanded state-of-charge to an elevated state-of-charge to increase the discharge capability to achieve the first threshold and maintaining the commanded state-of-charge at the elevated state-of-charge until the discharge capability achieves the first threshold.

Abstract: A powertrain system includes an internal combustion engine rotatably coupled via an input member to a transmission. The transmission has a hydraulic circuit including a hydraulic fluid pump directly mechanically coupled to the input member. A computer-implemented method for operating the powertrain system includes, in response to a command to execute an engine autostop maneuver, determining an engine speed ramping profile to achieve a desired stopped engine position. Hydraulic pressure in the hydraulic circuit is controlled in response to the engine speed ramping profile and engine speed during said engine autostop maneuver.
