Title: Crankshaft position sensing with combined starter alternator

A crankshaft position sensing apparatus is described for use with an engine having a combined starter/alternator assembly. The crankshaft position sensing apparatus includes a tone ring with a sensor and bandpass filter, having a cylinder identification input from a camshaft sensor, and a gain limiter. The sensing apparatus mounts near the rotor of the combined starter/alternator assembly. The filtered crankshaft position signal can then be input into a vehicle system controller and an inner loop controller. The starter/alternator assembly in combination with an internal combustion engine is particularly useful for a hybrid electric vehicle system.
