摘要：A method for operating a powertrain system including a torque machine coupled to an internal combustion engine that coupled to a transmission includes, upon commanding a shift in a transmission operating range, activating an immediate response mode to effect the shift. Activating the immediate response mode includes controlling the engine to achieve a predicted engine torque command, and controlling motor torque of the torque machine in response to a difference between an actual engine torque and an immediate crankshaft torque for shift command. An arbitrated predicted motor torque is determined A possible crankshaft torque is determined in response to the arbitrated predicted motor torque and the predicted engine torque command. Operation of the transmission at the end of the shift event is commanded in response to the possible crankshaft torque. A predicted response mode is activated to complete the shift in the transmission operating range.
