Abstract:
1. Method for controlling a powertrain comprising 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 through selective application of a plurality of clutches, said method comprising: commanding a shift from a fixed gear operating range state to a second operating range state, said second operating range state achieved without activating an oncoming clutch; commanding decreased reactive torque through an off-going clutch during a torque phase of said commanded shift; and operating a control module to decrease said reactive torque through said off-going clutch through control of engine input torque, comprising monitoring a requested output torque,
