When an accelerator pedal is released while a vehicle is running, a lockup clutch is unlocked. Simultaneously, ignition timing is retarded and a fuel-cut operation to stop fuel supply to an internal combustion engine is performed. However, when it is predicted that a fuel recovery is to be performed after unlocking the lockup clutch, execution of the fuel-cut operation is prohibited. A shock due to the fuel recovery after the fuel-cut operation performed when the accelerator pedal is released is thereby prevented.
