Method of decoding a CAM signal for an internal combustion engine

摘要

The CAM signal of a four-stroke internal combustion engine that also includes a CRANK signal having a sync feature is decoded by defining an observation window of predefined duration with respect a pulse transition of the CAM signal. The CAM signal is uniquely decoded during the observation window by monitoring for a pulse transition of the CAM signal and the sync feature of the CRANK signal.
