摘要

PROBLEM TO BE SOLVED: To prevent a driver from feeling a rapid change of moment during a mode transition in an operating method of an internal combustion engine of a vehicle in which fuel is directly supplied to a combustion chamber 4 and ignited at an ignition timing ZW capable of being previously determined using an ignition device 9, the internal combustion engine 1 is driven in at least two modes, the moment depends on an amount of air in a first mode, the moment depends on a fuel amount TI in a second mode, and the ignition timing ZW depends on the ignition timing which is taken out of a character map with respect to each of the modes. SOLUTION: At transition from the first mode to the second mode, matching and/or filtering of the ignition timing ZW is performed so as to generate a successive transition.
