Method and apparatus for controlling a multi-mode powertrain system
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.
