    摘要： A powertrain system includes a transmission operative to transfer power between a plurality of power actuators and an output member, and an energy storage device. A method for controlling the powertrain system includes establishing a first set of electric power limits and a second set of electric power limits for the energy storage device, determining a preferred input power from a first power actuator based upon the first set of electric power limits, determining a first set of power constraints for constraining input power from the first power actuator and a second set of power constraints for constraining output power from the output member based upon a second set of electric power limits, and controlling operation of the powertrain system based upon the preferred input power, the first set of power constraints, and the second set of power constraints.

    摘要： A method for operating a powertrain system including a torque machine coupled to a drive wheel of a vehicle includes determining a regenerative braking capacity of the powertrain system. In response to a net operator torque request including a braking torque request, a friction braking torque command to operate a friction brake system and a regenerative braking torque request for the torque machine are coincidentally generated, a torque command is generated for controlling operation of the torque machine in response to the regenerative braking torque request, and the friction braking torque command is adjusted by an amount corresponding to a difference between the braking torque request and the regenerative braking torque request.
