Abstract
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.
