Document Type and Number:
WIPO Patent Application WO/2016/088336
Kind Code:
A1
Abstract:
If the internal combustion engine (20) is currently performing all-cylinder operation, which involves operating all of the cylinders (201), then an air-fuel ratio estimation unit (106) of an ECU (1) carries out an estimation of the air-fuel ratio of the cylinders (201) using a first observer. Meanwhile, if the internal combustion engine (20) is currently performing reduced-cylinder operation, which involves pausing a portion of the cylinders (201) and operating the remaining cylinders (21), then an estimation of the air-fuel ratio of the cylinders (201) is not carried out using the first observer.
