METHOD AND APPARATUS FOR MEASURING AND CORRECTING AN IN-CYLINDER PRESSURE MEASUREMENT

Document Type and Number:

WIPO Patent Application WO2005108763

Kind Code:

A3

Abstract:

A method and apparatus for obtaining a corrected engine operational parameter value, using cylinder pressure information. A real pressure sensor signal output from a sensor (41D) is compared for discrepancies with an estimated output from engine pressure model (42A), including an engine model and a sensor model. The engine pressure model is corrected dependent on the discrepancy and the model engine pressure is then taken as the output value.
