Abstract:
An engine misfire is identified by ordinary engine misfire detection processing when the operating condition of an engine comprising a rotation speed Ne and a torque Te does not belong to a resonance region of a rear portion including a damper as a torsion element (S120), and an engine misfire is identified by resonance-region engine misfire detection processing, which is different from the ordinary engine misfire detection processing, when the operating condition of an engine belongs to a resonance region of a rear portion including a damper (S130). This enables an engine misfire to be identified more reliably and with good accuracy regardless of whether the operating condition of an engine belongs to a resonance region of a rear portion including a damper.
