Abstract

Official abstract text for this publication.

Feedback control is executed based on a measured CA10 and a measured CA50 that are calculated based on measured data for MFB. During steady operation a correlation index value I RA that shows a degree of correlation between the measured data and reference data corresponding thereto is calculated. During transient operation, a correlation index value I AA that shows a degree of correlation between the measured data and measured data that is measured immediately prior to the measured data is calculated. If the correlation index value I RA or the correlation index value I AA is less than a determination value I th , control is performed to prohibit reflection in the aforementioned feedback control of each of the measured CA10 and the measured CA50 which are measured in the combustion cycle in which the relevant correlation index value is calculated.

First claim

Opening claim text (preview).

1 . A control device for an internal combustion engine, comprising: an in-cylinder pressure sensor that is configured to detect an in-cylinder pressure; a crank angle sensor that is configured to detect a crank angle; and a control unit that is configured to: calculate measured data for mass fraction burned that is synchronized with a crank angle, based on an in-cylinder pressure that is detected by the in-cylinder pressure sensor and a crank angle that is detected by the crank angle sens…
