Title:
SYSTEMS AND METHODS FOR ESTIMATING TIME OF ENGINE EVENT
Document Type and Number:
Japanese Patent JP2016200141
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To detect various not only engine events that occur during normal engine operation but events that may forecast a potential engine malfunction or engine failure.SOLUTION: Systems and methods for estimating when an engine event occurs are provided. The system includes a controller configured to receive a first signal from at least one knock sensor coupled to a combustion engine, receive a second signal from at least one engine crankshaft sensor coupled to the combustion engine, transform the first and second signals into a plurality of feature vectors using a multivariate transformation algorithm, determine an expected window of an engine event with a statistical algorithm, center a segment of the plurality of feature vectors around the expected window, estimate, using the statistical algorithm, a time in the expected window corresponding to when the engine event occurred, and adjust operation of the combustion engine on the basis of the time.SELECTED DRAWING: Figure 3
