摘要： In an engine 5 including an in-cylinder injector, the valve timing of an intake valve is retarded by VVT (Variable Valve Timing) controlled by an engine ECU to decompress in a combustion chamber at engine startup. In accordance with a configuration in which the valve timing of intake valve is advanced in a stepped manner from an initial set value, fuel injection from in-cylinder injector is inhibited during the time when the advance is equal to or below a predetermined standard value, and fuel injection from in-cylinder injector is allowed when exceeding the predetermined standard value, whereby degradation in the exhaust emission level in accordance with start time decompression control can be suppressed.

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.
