Patent number: 10947922Abstract: A first intake air amount an engine is calculated based on a detected value of an intake air flow rate of an air flowmeter. A second intake air amount is calculated based on any one of a detected value of an intake pipe pressure and a throttle opening degree instead of the detected value of the intake air flow rate. When it is determined that the intake pulsation is not large, a difference amount of the second intake air amount from the first intake air amount is calculated. A corrected second intake air amount, which is a sum of the second intake air amount and the difference amount, is set as an intake air amount calculated value when it is determined that the intake pulsation is large.Type: GrantFiled: June 27, 2019Date of Patent: March 16, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takafumi Yamada, Hiroyuki Shibata, Shunsuke Kurita, Takahiro Anami
