Title:
エンジン制御装置
Document Type and Number:
Japanese Patent JP7188360
Kind Code:
B2
Abstract:
An engine controller, an engine control method, and a memory medium are provided. A second calculation process (P2) calculates an intake air amount without using a detected value (GA) of the intake air flow rate. A guard process (P9) sets a difference amount learning value (DEV[i]) as a learning reflected value (DREF) (S350) when the difference amount learning value (DEV[i]) is less than or equal to an upper limit guard value (UPPER) (S310: YES) and greater than or equal to a lower limit guard value (LOWER) (S320: YES). A calculation method switching process (P4) sets a sum of a second intake air amount (MC2) and the learning reflected value (DREF) as a calculated value of the intake air amount when it is determined that an intake air pulsation is great.
