ABSTRACT:
Engine misfire is detected by using threshold values that vary depending on whether damping control is executed. First threshold values are adopted at the setting of a gearshift position to a drive position or a park position where damping control is performed to reduce the vibration of an engine. Second threshold values are adopted at the setting of the gearshift position to a neutral position where the damping control is not performed, the second threshold values being greater than the first threshold values. Engine misfire detection is carried out by processing using the first and second threshold values.
