摘要
A signal indicating that a road on which a vehicle is travelling is not a rough road is output when a fluctuation frequency of an engine rotational speed and a fluctuation frequency of a combustion pressure are in approximate agreement, and a fluctuation amplitude of an engine rotational speed is greater by a predetermined value or above than a fluctuation amplitude of a combustion pressure. In other cases a signal indicating that the road on which the vehicle is travelling is not a rough road is output. During rough road travel, misfire detection based on engine rotational speed or combustion pressure is inhibited.
