Abstract
A method for operating a powertrain system to transfer torque among an engine, torque machines, and a driveline in response to an output torque request includes executing a selection scheme to evaluate operating in a plurality of candidate powertrain states including a pseudo-electric vehicle (EV) range responsive to the output torque request. A respective minimum cost for operating the powertrain system in each of the candidate powertrain states including the pseudo-EV range is determined. A preferred powertrain state is selected, and is one of the candidate powertrain states including the pseudo-EV range 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.
