PROBLEM TO BE SOLVED: To accurately determine presence of an abnormal cylinder and stabilize a travel condition when an abnormal cylinder is present in a hybrid vehicle comprising an engine connected to driving wheels through a power transmission system and an electric motor connected to the power transmission system through a clutch.SOLUTION: When an engine rotation speed Ne is included in a resonance rotation speed range and it is determined that no abnormal cylinder with a misfire is present, an engine ECU transmits a command signal to change an operation state of a clutch C2 between a motor generator and a power transmission system from a state before the rotation speed Ne is included in the resonance rotation speed range, to TMECU (S130 - S170), while when it is determined that one or more abnormal cylinders are present, the engine ECU transmits a command signal to change an operation state of engagement components of the power transmission system from the state before the rotation speed Ne is included in the resonance rotation speed range, to the TMECU (S200).SELECTED DRAWING: Figure 2

    【課題】動力伝達装置を介して駆動輪に連結されるエンジンと、クラッチを介して動力伝達装置に連結される電動機とを含むハイブリッド車両において、異常気筒の有無を精度よく判定し、かつ異常気筒が存在している際の走行状態を安定化させる。【解決手段】エンジンECUは、エンジンの回転数Neが共振回転数帯に含まれる際、失火が発生した異常気筒が存在していないと判定されている場合には、モータジェネレータと動力伝達装置との間のクラッチC2の作動状態を回転数Neが共振回転数帯に含まれる前の状態から変更するための指令信号をTMECUに送信し(S130−S170)、異常気筒が存在していると判定されている場合には、動力伝達装置の係合要素の作動状態を回転数Neが共振回転数帯に含まれる前の状態から変更するための指令信号をTMECUに送信する(S200)。【選択図】図2
