1. A method for controlling a powertrain system comprising a plurality of power actuators, a transmission device and an energy storage device, the transmission device operative to transfer power between the power actuators and an output member to generate an output torque, the method comprising:
- determining an operator request for power from the output member;
determining a first set of electric power constraints for the energy storage device;
determining a set of power constraints for a first power actuator based upon the first set of electric power constraints for the energy storage device;
determining a second set of electric power constraints for the energy storage device;
determining a set of power constraints for a second power actuator based upon the second set of electric power constraints for the energy storage device;
controlling the first power actuator based upon the set of power constraints for the first power actuator; and
controlling the second power actuator based upon the set of power constraints for the second power actuator.
