PROBLEM TO BE SOLVED: To carry out an accurate misfire detection at the enforcing time of a vibration control and continue a favorable engine operation. SOLUTION: This hybrid vehicle is provided with an engine 10, motor generator 10 (power generation motor) 11, inverter 12 and battery 13 as a main constitution. A motor ECU 22 enforces the vibration control at the operation time of the engine 10 so as to deny the torque change of the engine 10 by the motor generator 11 connected to a crank shaft 14. Namely, the torque correction amount for denying the torque change of the engine 10 is calculated and the torque command value to the motor generator 11 is corrected by the torque correction amount. The engine ECU 21 detects the misfire state of the engine 10 based on the torque correction amount of the motor generator 11 at the enforcing time of the vibration control. |
