A method for controlling a powertrain system includes monitoring an operator torque request, selecting a candidate powertrain system operating point, and determining a preferred engine (14) torque range, a preferred torque machine (56,72) torque range, and a preferred energy storage device (74) output power range. The method further includes determining an engine (14) torque, a torque machine (56,72) torque, and an energy storage device (74) output power based upon the operator torque request and the candidate powertrain system operating point. Power costs for operating the powertrain at the candidate powertrain system operating point are determined based on the determined engine (14) torque, the determined torque machine (56,72) torque, and the determined energy storage device (74) output power range. Penalty costs are determined relative to the preferred engine (14) torque range, the preferred torque machine (56,72) torque range, and the preferred energy storage device (74) output power range for operating the powertrain at the candidate powertrain system operating point. And, an operating cost for operating the powertrain at the candidate powertrain system operating point is determined based on the power costs and the penalty costs. |
