Abstract
A powertrain includes an electric motor providing propulsion torque to a transmission input shaft, an internal combustion engine, and an engine disconnect clutch selectively providing torque transfer between the engine and the motor. A method to control a flying engine start in the powertrain includes monitoring an output torque request, determining the propulsion torque to the transmission input shaft based upon the output torque request, determining a compensation torque to be provided to the engine disconnect clutch for the flying engine start, and controlling the motor to provide a motor torque based upon a sum of the propulsion torque and the compensation torque.
