    摘要: A vehicle includes an engine, a first MG (motor generator), a second MG, a motive power split device, and an ECU. ECU temporarily determines whether or not an imbalance abnormality has occurred based on an air-fuel ratio, and when it is temporarily determined that the imbalance abnormality is present, controls the engine such that the engine is in an idle state and formally determines whether or not the imbalance abnormality has occurred based on fluctuations in engine rotation speed. During a stop at idle, ECU determines whether or not the formal determination process of the imbalance determination is ongoing and carries out pressing control to cause the first MG to generate pressing torque Tp when the formal determination process is not ongoing and does not carry out the pressing control so as not to cause the first MG to generate pressing torque Tp when the formal determination process is ongoing.

    摘要: Provided is a vehicle including an engine, a first MG (motor generator), a second MG, a power split device that couples them, and an ECU. ECU determines whether or not to permit execution of pressing control for suppressing idling vibrations produced by the power split device in an idling state of the engine depending on whether or not the combustion state of the engine is good, and sets a permission flag in accordance with a determination result. ECU determines whether or not the vehicle is stopping and is in the idling state. While the vehicle is stopping and is in the idling state and if the permission flag F is “ON”, ECU executes pressing control to cause the first MG to produce pressing torque Tp. If the permission flag F is “OFF”, ECU does not execute pressing control so that the first MG does not produce pressing torque Tp.

    摘要: A control device for an internal combustion engine includes: a variable valve timing mechanism that changes a valve timing; and a control unit that controls a change of the valve timing. The control unit sets an engine stop request-time target valve timing that is a target valve timing at the time when a request for an engine stop is issued, starts control for changing the valve timing coincides with the engine stop request-time target valve timing and causes the internal combustion engine to operate at an idle at the time when the request for the engine stop is issued, starts a process of stopping operation of internal combustion engine at the time when the valve timing has reached a predetermined valve timing.

    摘要: After an engine stop duration exceeds a predetermined time period (that is, if a decision outcome of S100 is positive), diagnosis of a leakage mechanism, which is a relief valve, for diagnosing the presence/absence of an abnormality is not performed during a current engine stop (S102). Therefore, even if the fuel pressure in the high-pressure fuel system is reduced to a low-pressure level due to temperature decrease as though fuel has been leaked in a state in which high-pressure fuel in a high-pressure fuel system cannot be leaked due to an abnormality in the relief valve, it generally occurs after the predetermined time period since such a decrease to a low-pressure level due to the temperature decrease is slow. Thus, an erroneous diagnosis as being normal is prevented from being made since the diagnosis has been suspended when the fuel pressure becomes equal to the low-pressure level.
