PROBLEM TO BE SOLVED: To hardly cause a wrong determination of misfire even when communication between control portions is defective.SOLUTION: A hybrid vehicle has an internal combustion engine, and an electric motor which is connected to the internal combustion engine via a torsional element. A control device comprises: a first control portion that controls the internal combustion engine using output of a first detecting portion (S101) that detects rotation speed of the internal combustion engine; and a second control portion that controls the electric motor using output of a second detecting portion that detects rotation speed of the electric motor and transmits rotation speed information specified from the rotation speed of the electric motor to the first control portion. The first control portion calculates resonance influence components using the rotation speed information from the second control portion; calculates determination values using the resonance influence components and the rotation speed of the internal combustion engine (S101-114); determines the misfire of the internal combustion engine by comparing the determination values with a predetermined threshold (S118 and S119); and when communication between the second control portion and the first control portion is defective, changes the predetermined threshold into a value which is hardly determined to be the misfire, and then determines the misfire (S115 and 117) or prohibits a determination of the misfire.SELECTED DRAWING: Figure 4

    【課題】制御部間の通信が不良であっても失火の誤判定を生じ難くする。【解決手段】ハイブリッド車両は、内燃機関と、ねじれ要素を介して内燃機関に接続される電動機とを有する。制御装置は、内燃機関の回転速度を検出する第1検出部(S101)の出力を用い内燃機関を制御する第1制御部と、電動機の回転速度を検出する第2検出部の出力を用い電動機を制御し、電動機の回転速度から特定される回転速度情報を第1制御部に送信する第2制御部とを備える。第1制御部は、第2制御部からの回転速度情報を用い共振影響成分を算出し、共振影響成分と内燃機関の回転速度とを用いて判定値を算出し(S101〜114)、判定値と所定閾値との比較によって内燃機関の失火を判定し(S118,119)、第2制御部と第1制御部との通信が不良であるときは、所定閾値を失火と判定され難い値に変更して失火を判定する(S115,117)または失火の判定を禁止する。【選択図】図4
