ABSTRACT:
A method and article of manufacture are provided for operating an internal combustion engine adapted to transmit torque to a hybrid transmission. The method comprises determining engine input torque transmittable to the hybrid transmission for each of a plurality of engine states. Costs are determined for operating the engine and hybrid transmission in the engine states to substantially meet an operator torque request. A preferred engine state is selected based upon the determined costs. The engine is controlled based upon the preferred engine state to substantially meet an operator torque request.
