<p>A powertrain system includes a hybrid transmission device (10) operative to transfer power between an input member (12) and torque machines (56,72) and an output member (64) in one of a plurality of operating range states. The torque machines (56,72) are connected to an energy storage device (74). A method for operating the powertrain system includes determining a permissible range of input operating points to the input member (12), determining ranges of motor torques for the torque machines (56,72), determining an available power range from the energy storage device (74), selecting a candidate input operating point within the permissible range of input operating points, and determining maximum and minimum achievable output torques transferable to the output member (64) for the candidate engine operating point within the ranges of motor torques for the torque machines (56,72) and within the available power range from the energy storage device (74) in a candidate operating range state.</p> |
