CONTROLLER OF INTERNAL COMBUSTION ENGINE

摘要

[Problem] To suppress a slip of clutch in an automatic transmission when an internal combustion engine is automatically restarted. [Solution] In a case that the internal combustion engine 1 is cranked up from a stopped position of piston 10 in a restart-time first ignition cylinder which is scheduled to firstly start a combustion at the time of automatic restart of internal combustion engine 1 under an automatic stop of internal combustion engine 1 during an idling-stop control, a restart-time ignition time interval between a time point when the cranking of internal combustion engine 1 is started and a time point when a restart-time first ignition cylinder is initially ignited is calculated. A drive-start timing of starter motor 19 is delayed according to this restart-time ignition time interval. Thereby, the cranking of internal combustion engine 1 is carried out by the starter motor 19 under a state where hydraulic pressure supplied from the electric oil pump 27 has increased. Therefore, the slip in the clutch 24 of CVT 14 can be suppressed when gas mixture in the restart-time first ignition cylinder is initially ignited.
