Patent number: 11193433Abstract: An engine controller, an engine control method, and memory medium are provided. A second calculation process calculates an intake air amount without using a detection result of an air flow meter. The determination process determines that intake air pulsation is great if it is confirmed that a difference between an average flow rate and a minimum flow rate is great. The average flow rate is an average value of an intake air flow rate within a period of the intake air pulsation. The minimum flow rate is a minimum value of the intake air flow rate within the period. When it is determined that the intake air pulsation is great, a calculation method switching process selects a calculated value of the intake air amount that is obtained by the second calculation process.Type: GrantFiled: August 3, 2020Date of Patent: December 7, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takafumi Yamada, Takahiro Anami, Shunsuke Kurita

Patent number: 11143134Abstract: An engine controller is provided. A second calculation process calculates an intake air amount without using an output of an air flow meter. A second determination process determines whether an intake air pulsation in an intake passage is great without using the output of the air flow meter. When the intake air pulsation is determined to be great by at least one of a first determination process and the second determination process, a calculation method switching process selects the calculated value of the intake air amount obtained by the second calculation process as a calculated value of the intake air amount used to determine an operation amount of an actuator.Type: GrantFiled: July 1, 2020Date of Patent: October 12, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takafumi Yamada, Shunsuke Kurita

Patent number: 11067026Abstract: An engine controller, an engine control method, and a memory medium are provided. A second calculation process calculates an intake air amount without using a detected value of the intake air flow rate. A guard process sets a difference amount learning value as a learning reflected value when the difference amount learning value is less than or equal to an upper limit guard value and greater than or equal to a lower limit guard value. A calculation method switching process sets a sum of a second intake air amount and the learning reflected value as a calculated value of the intake air amount when it is determined that an intake air pulsation is great.Type: GrantFiled: September 29, 2020Date of Patent: July 20, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Shunsuke Kurita

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
