Title:

INTERNAL COMBUSTION ENGINE CONTROL DEVICE AND INTERNAL COMBUSTION ENGINE CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2019/163507

Kind Code:

A1

Abstract:

The present invention addresses the problem of evaluating combustion stability accurately, even during a transient operation, in consideration of the influence of tendency. Provided is an internal combustion engine control device comprising: a combustion energy calculation unit 210 which calculates a combustion energy W_t of each combustion cycle of an internal combustion engine; a tendency calculation unit 230 which calculates a tendency Tr of change in the combustion energy W_t calculated by the combustion energy calculation unit 210 in a plurality of combustion cycles; and a combustion stability determination unit 250 which determines combustion stability on the basis of the combustion energy W_t in the plurality of combustion cycles and the tendency Tr of change calculated by the tendency calculation unit 230.
