Abstract
A method for detecting sustained combustion in the engine of a hybrid electric powertrain that includes a starter/generator driveably connected to the engine, a transmission for driving a load, and an input clutch for opening and closing a drive connection between the electric machine and the transmission, includes the steps of using the starter/generator to produce torque and crank the engine, preparing the engine to produce combustion, producing torque capacity across the input clutch while slipping the clutch, and continuing use of the starter/generator until a sum of the crankshaft torque applied by the starter/generator and the crankshaft torque applied by the transmission is less than some torque threshold for a predetermined period length.
