1. Method for controlling a powertrain system including a transmission device operative to transfer power between an input member and a plurality of torque machines and an output member, the torque machines connected to an energy storage device and the transmission device operative in one of a plurality of operating range states, the method comprising:

  • monitoring available power from the energy storage device;

    determining system constraints;

    determining constraints on an output torque to the output member based upon the system constraints and the available power from the energy storage device;

    determining an operator torque request;

    determining an output torque command based upon the constraints on the output torque and the operator torque request; and

    determining preferred torque commands for each of the torque machines based upon the output torque command.
