Abstract
A method of stopping an engine crankshaft includes selecting a target angular position at which the engine crankshaft is to be stopped and detecting an actual angular position of the engine crankshaft and a rotational speed of the engine crankshaft. A stopping torque in calculated based on the actual angular position of the engine crankshaft and the rotational speed of the engine crankshaft. The stopping torque is applied to the engine crankshaft via a motor/generator operably connected to the engine crankshaft. The engine crankshaft is stopped at the target angular position via the application of the stopping torque.
