  • Engine misfire determination device and vehicle
    Patent number: 10788397
    Abstract: A misfire determination device includes: a combustion fluctuation canceled value acquisition unit that acquires a first combustion fluctuation canceled value corresponding to a first angle position and a second combustion fluctuation canceled value corresponding to a second angle position; a combustion fluctuation manifested value calculation unit that calculates a first fluctuation manifested value by removing the first combustion fluctuation canceled value from a rotation speed at the first angle position, and calculates a second fluctuation manifested value by removing the second combustion fluctuation canceled value from a rotation speed at the second angle position; a first-order difference calculation unit that calculates a first-order difference between the first fluctuation manifested value and the second fluctuation manifested value; and a specific cylinder misfire determination unit that determines a misfire in a specific cylinder by using the first-order difference.
