A lock-up mechanism switching control of a torque converter, that is, a switching control of a lock-up OFF state and a lock-up ON state, and a compression ratio varying control of an internal combustion engine are performed to be cooperated with each other. For example, when the compression ratio is switched from the high compression ratio to the low compression ratio and the lock-up mechanism of the torque converter is switched from the lock-up OFF state to the lock-up ON state, the lock-up mechanism is switched to the lock-up ON state after the compression ratio is shifted to the low compression ratio side. With this, the lock-up mechanism of the torque converter is not in the lock-up ON state in the high compression ratio state. Accordingly, it is possible to suppress generation of vehicle vibration (booming noise).
