Title:
CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2024/013953
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a control device which is for an internal combustion engine and which can reduce the difference between a corrected air flowrate and an actual air flowrate by appropriately correcting an output value of a flowrate sensor provided in an intake air passage of the internal combustion engine. A control device 100 for an internal combustion engine 10 comprises: a correction amount derivation unit 107 that derives a correction amount for an output value of a flowrate sensor 17; and a flowrate correction unit 113 that calculates a flowrate of air flowing through an intake air passage 20 by correcting the output value of the flowrate sensor 17 on the basis of the correction amount. The correction amount derivation unit 107 includes: a normalization unit 108 that normalizes the output value of the flowrate sensor 17 for each wave form of one wavelength acquired from an output value, of the flowrate sensor 17, acquired during a prescribed period; and an NN calculation unit 109 that calculates a correction amount for the output value of the flowrate sensor 17 during the prescribed period, from the normalized output value of the flowrate sensor 17.
