The transmission is operative in one of a plurality of operating range states through selective application of torque transfer clutches and the engine is operatively coupled to a main hydraulic pump to supply pressurized fluid to a hydraulic circuit operative to apply the torque transfer clutches. A method for controlling the powertrain system includes determining an output torque request to the output member, determining a pressure output of the main hydraulic pump based upon an engine input speed, calculating a clutch reactive torque capacity for each applied torque transfer clutch based upon the pressure output of the main hydraulic pump, and determining a preferred engine input speed to achieve the clutch reactive torque capacity to meet the output torque request to the output member.

摘要： A powertrain includes an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and an electric machine adapted to selectively transmit mechanical power to an output member. A method for controlling the powertrain includes operating the transmission in an operating range state wherein input speed can operate independent of output speed and wherein a reactive torque is transmitted through the transmission. The method further includes monitoring commands affecting a requested output torque, monitoring a calculated output torque, and prioritizing between an input acceleration of the transmission and an output torque of the transmission based upon whether operating the transmission in the operating range state is in transient operation or stable operation.
