| 20100174472 | CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - A knock control apparatus includes: a knock sensor for detecting knock of an internal combustion engine; a signal processing section for calculating a knock intensity; and knock determination level setting sections: for calculating an average value of the knock intensity; for calculating, based on the average value, an overall variance of the knock intensity of an entirety of a frequency distribution, a higher variance of the knock intensity above the average value, and a lower variance of the knock intensity below the average value; for calculating a standard deviation of the knock intensity from the overall variance; for presetting a value allowing the frequency distribution of the knock intensity to be a predetermined confidence interval as a confidence coefficient; and for setting a sum of the average value and a value obtained by multiplying the standard deviation by the corrected confidence coefficient as a knock determination level. | 07-08-2010 |
| 20110093186 | CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - Control apparatus for an internal combustion engine including: a second knock detection unit for detecting occurrence of a second knock due to an effective compression ratio when ignition timing is on a retard side of a predetermined value in the case where a first knock is detected; a second knock suppression unit for suppressing the second knock when the second knock is detected; a first abnormal ignition detection means for detecting occurrence of first abnormal ignition due to the pre-ignition or the post-ignition when a knock intensity of the second knock is equal to or larger than a predetermined value; and a first abnormal ignition suppression unit for suppressing the first abnormal ignition by performing fuel control for the internal combustion engine when the first abnormal ignition is detected. | 04-21-2011 |
