Title:
INTERNAL COMBUSTION ENGINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/124135
Kind Code:
A1
Abstract:
An internal combustion engine control device capable of properly performing an air/fuel ratio control and an ignition timing control according to an actual suction air amount even when reliability of the detection result of the operating conditions of a variable suction mechanism is lowered. A control device (1) for controlling an air/fuel ratio and an ignition timing is provided with an ECU (2). The ECU (2) calculates a target air/fuel ratio KCMD (step 22), calculates an air/fuel ratio correction factor KSTR for feedback-controlling an air/fuel ratio (step 2-7), calculates the statistical processing value KAF&lowbar LS of an air/fuel ratio index value (step 82), calculates a corrected valve lift Liftin&lowbar comp and a corrected cam phase Cain&lowbar comp according to the statistical processing value KAF&lowbar LS (steps 81-92), and determines a fuel injection amount TOUT according to the corrected valve lift Liftin&lowbar comp, the corrected cam phase Cain&lowbar comp and the air/fuel ratio correction factor KSTR (steps 20-25).
