Method and apparatus for detecting crankshaft angular position

A method and apparatus for detecting an engine crankshaft angular position which provides for fast starting of the engine. A target wheel (10) and sensor (24 and 26) combination generate an analog signal which is converted into a 24 bit digital output which repeats every 360 DEG rotation of the cran...

Zusammenfassung:	A method and apparatus for detecting an engine crankshaft angular position which provides for fast starting of the engine. A target wheel (10) and sensor (24 and 26) combination generate an analog signal which is converted into a 24 bit digital output which repeats every 360 DEG rotation of the crankshaft. Each bit represents a particular angular position of the crankshaft. Any 6 sequential bits in the repeating 24 bit digital output sequence form a unique pattern. By monitoring the first six bits generated (90 DEG of crankshaft rotation) during start-up, a crankshaft angular position can be determined, thereby enabling fast starting of the engine.
