Abstract: A powertrain system is described, and includes an internal combustion engine and an electric machine configured to generate propulsion torque responsive to a driver torque request. A method for operating the powertrain system includes determining, in response to a request to execute an engine autostart operation, whether a driveline torque sag may occur. The method further includes forgoing executing the engine autostart operation when it is determined that a driveline torque sag will occur during the execution of the engine autostart operation.

Abstract: A method of managing an operating state of an electrified powertrain includes a controller identifying a plurality of available operating regions defined by at least one available operating state of the powertrain, each operating region representing a distinct range of operating conditions. The available operating regions include an avoidance region defining a plurality of unwanted operating conditions and separating a first allowable operating region from a second allowable operating region such that the first and second allowable operating regions are noncontiguous. The method identifies at least one ideal operating condition in each of the available operating regions, determines a preferability factor and stabilization factor for each of a current and each of the ideal operating conditions, and arbitrates the factors to identify one of the current and ideal operating conditions as an optimized operating condition to produce a required parameter value.

Abstract: A method for operating a multi-mode powertrain system includes executing a selection scheme to evaluate operating the powertrain system in a plurality of candidate powertrain states including a one-motor electric vehicle (EV) range responsive to an output torque request. A respective minimum cost for operating the powertrain system in each of the candidate powertrain states including the one-motor EV range is determined. A preferred powertrain state is selected as one of the candidate powertrain states including the one-motor EV range that is associated with a minimum of the respective minimum costs. The powertrain system is controlled in the preferred powertrain state responsive to the output torque request.
