Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/260997
Kind Code:
A1
Abstract:
Provided is an internal combustion engine control device with which it is possible to highly precisely calculate an air amount. This internal combustion engine control device 100 comprises a period measurement unit 201, a physical value conversion unit 203, a signal correction processing unit 205, and an average air amount computation unit 206. The physical value conversion unit 203 converts a cycle measured by the period measurement unit 201 to an air amount. The signal correction processing unit 205 applies weighting, on the basis of the period, to the air amount calculated by the physical value conversion unit 203. The average air amount computation unit 206 computes an average air amount for the air amounts that were weighted by the signal correction processing unit 205 in a prescribed computation period.
