  • Publication number: 20200018253
    Abstract: 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.

  • Patent number: 10458489
    Abstract: The selectable one-way clutch includes a pocket plate, a notch plate, a cover plate, and plate-like struts. A one end portion of each strut is provided with an engagement surface and a projecting portion. Each strut comes into an erect state in which the engagement surface of the strut erects from the other surface of the cover plate toward the notch plate side. The selectable one-way clutch moves the notch plate in the axial direction to change a distance in the axial direction between the pocket plate and the notch plate, thereby carrying out switching between an out-of-engagement state in which the erecting struts cannot contact with the notches and a one-way clutch state in which the erecting struts can contact with the notches.
