ABSTRACT:
A method for controlling a vehicle launch using a transmission having an input, a current gear, an input clutch associated with a target gear and an output, an engine and an electric machine for driving the input, includes the steps of determining a desired magnitude of torque to be produced at the transmission output, producing a predetermined magnitude of torque capacity of the input clutch, operating the engine such that a magnitude of torque at the transmission output is substantially equal to the desired transmission output torque, determining an crankshaft speed error, determining a desired change in torque at the transmission input that will reduce the crankshaft speed error, adjusting a magnitude of torque produced by the first electric machine such that the magnitude of torque at the transmission input is substantially equal to the desired torque at the transmission input, and engaging the input clutch.
