Abstract
A system and method for obtaining engine diagnostic and prognostic information utilizing current, time and crank position data obtained from the starter motor during the starting of an engine and represented as a starter motor current waveform. The time domain waveform is transformed to the spatial domain. Thereafter, the spatial waveform is deconvolved into its constituent components using known digital signal processing, such as Fourier Transformations, and along with derived engine parameters provide engine status and diagnostic information. Weibull techniques may be used to further process the engine status and diagnostic information to improve accuracy.
