ABSTRACT:
A powertrain system includes a transmission operative to transfer power between an input member and first and second torque machines and an output member. The first and second torque machines are connected to an energy storage device and the transmission is operative in a continuously variable operating range state. A method for controlling the powertrain system includes selecting an independently controllable parameter for the powertrain system, determining maximum and minimum motor torque constraints for the first and second torque machines and determining maximum and minimum power constraints for the energy storage device, determining maximum and minimum states for the independently controllable parameter for the powertrain system, and determining an achievable operating range for a parameter of interest based upon the maximum and minimum states for the independently controllable parameter for the powertrain system, the maximum and minimum motor torque constraints for the first and second torque machines and the maximum and minimum power constraints for the energy storage device.
