What is required is a control device capable of reducing the starting time of an internal combustion engine, and suppressing the transmission of torque shock to wheel side when a first engagement device shifts from a disengagement state to a slip engagement state and when the first engagement device shifts from the slip engagement state to a direct-coupling engagement state. After a request to start an internal combustion engine is made while a first engagement device is in a disengagement state and a second engagement device is in a direct-coupling engagement state, a control device starts first shift control for shifting the first engagement device from the disengagement state to a slip engagement state and second shift control for shifting the second engagement device from the direct-coupling engagement state to the slip engagement state, starts the rotation speed control of a rotating electric machine before the first engagement device shifts to the slip engagement state, and shifts the first engagement device from the slip engagement state to the direct-coupling engagement state after determining that the second engagement device has shifted to the slip engagement state.
