    Abstract: A powertrain system is configured to transfer torque to an output member. A method for controlling the powertrain system includes prioritizing a plurality of system torque constraint parameters. The system torque constraint parameters are sequentially applied in an order of descending priority. A feasible state for each of the sequentially applied system torque constraint parameters is determined. A solution set including the feasible states for all the sequentially applied system torque constraint parameters is determined, and employed to control operation of the powertrain system in response to an output torque request.

    Abstract: A vehicle includes an internal combustion engine coupled to an input member of a multi-mode transmission configured to transfer torque to an output member coupled to a ground wheel with the internal combustion engine in an ON state generating an input torque. A method for controlling the vehicle includes identifying an undesirable operating region including an input/output torque region for operating the multi-mode transmission. In response to an operator request for creep torque, motor torque is controlled from a torque machine coupled to the multi-mode transmission such that the multi-mode transmission is operating outside the undesirable operating region while a mechanical braking torque to the ground wheel is coincidentally controlled in response to an operator-commanded braking, the input torque from the engine, and the motor torque from the torque machine.
