A catalyst warm-up control is carried out in a state with a first exhaust valve closed and a second exhaust valve opened. After completion of the catalyst warm-up, if there is an acceleration request, exhaust gas temperature is acquired.

If the exhaust gas temperature is higher than the predetermined value, the second exhaust valve is fully closed to thereby introduce the whole amount of exhaust gas to a turbine. A vehicle control device that achieves both prevention of catalyst deactivation and acceleration performance enhancement can be thus provided.
