Abstract
A method of starting a vehicle may include providing power to a motor to spin the motor at a speed at least equal to a target engine cranking speed while a clutch configured to couple an engine and motor is open. The method may also include cutting power to the motor in response to the motor achieving the speed, and locking the clutch to couple the rotating inertias of the motor and a transmission with the engine to start the engine.
