Abstract: When a detected value for detecting a rich imbalance in air-fuel ratio among cylinders, in a state where an intake air amount of an engine falls within a low amount region, is lower than a first threshold corresponding to the intake air amount and is higher than or equal to a second threshold corresponding to the intake air amount, a hybrid electronic control unit controls the engine such that the intake air amount falls within a high amount region, and controls a motor generator such that electric power corresponding to a power increase amount is consumed. When the intake air amount falls within the high amount region, the hybrid electronic control unit detects a rich imbalance in air-fuel ratio among the cylinders by comparing the detected value with a third threshold corresponding to the intake air amount.

Abstract: A rotational fluctuation malfunction detection device for an internal combustion engine determines that fluctuations in output shaft rotational speed are “normal” when a rotational fluctuation value, obtained in a “disturbance fluctuation state” is below threshold L1. If rotational fluctuation value obtained in “disturbance fluctuation state” equals or exceeds L2, the rotational fluctuation malfunction detection device determines that the rotational fluctuation value is “abnormal.” However, when the rotational fluctuation value obtained in “disturbance fluctuation state” is equal to L1 or between L1 and L2, the rotational fluctuation malfunction detection device determines that the rotational fluctuation value is “normal” if the rotational fluctuation value obtained in the “non-disturbance state” is below L3, and the rotational fluctuation value is “abnormal” if the rotational fluctuation value obtained in the “non-disturbance state” equals or exceeds L3.

Abstract: A rotational fluctuation malfunction detection device for an internal combustion engine determines that fluctuations in output shaft rotational speed are “normal” when a rotational fluctuation value, obtained in a “disturbance fluctuation state” is below threshold L1. If rotational fluctuation value obtained in “disturbance fluctuation state” equals or exceeds L2, the rotational fluctuation malfunction detection device determines that the rotational fluctuation value is “abnormal.” However, when the rotational fluctuation value obtained in “disturbance fluctuation state” is equal to L1 or between L1 and L2, the rotational fluctuation malfunction detection device determines that the rotational fluctuation value is “normal” if the rotational fluctuation value obtained in the “non-disturbance state” is below L3, and the rotational fluctuation value is “abnormal” if the rotational fluctuation value obtained in the “non-disturbance state” equals or exceeds L3.
