A control device for a driving device, the driving device includes a transmission and a hydraulic pressure generating device. The hydraulic pressure generating device includes an oil pump and a first mechanism. The first mechanism is configured to decrease hydraulic pressure of an oil passage connected with the oil pump. The control device includes an ECU. The ECU is configured to control the engine rotational speed to a first rotational speed and maintain vehicle speed by gear shifting, in a case where, while a vehicle is running in a predetermined running state, fuel consumption is smaller when the engine is driven at the first rotational speed, compared to fuel consumption in the predetermined running state, the first rotational speed is a rotational speed at which the hydraulic pressure is decreased, the predetermined running state being a running state in which the hydraulic pressure is not decreased. |
