1. A control device that controls a vehicle drive device in which a rotary electric machine is provided in a power transfer path that connects between an internal combustion engine and wheels and in which a first friction engagement device is provided between the internal combustion engine and the rotary electric machine and a second friction engagement device is provided between the rotary electric machine and the wheels, wherein:
the control device executes rotational state control in which a rotational state of the rotary electric machine is controlled such that a target rotational state is established with torque of the internal combustion engine transferred to the wheels while a hydraulic pressure supplied to the first friction engagement device is controlled such that a rotational state of the internal combustion engine coincides with a target rotational state with both the first friction engagement device and the second friction engagement device in a slip engagement state, or with torque of the internal combustion engine transferred to the wheels with the first friction engagement device in a direct engagement state and with the second friction engagement device in a slip engagement state; and the control device executes hydraulic pressure regulation control in which a hydraulic pressure supplied to the second friction engagement device in the slip engagement state is controlled on the basis of torque of the rotary electric machine produced during the rotational state control while the second friction engagement device is transitioned from the slip engagement state to a direct engagement state, wherein: the control device further executes target torque decision control in which target torque for the rotary electric machine is decided on the basis of a difference between a required drive force for driving the wheels and torque transferred from the internal combustion engine to the rotary electric machine; the control device executes as the rotational state control rotational speed feedback control in which a rotational speed of the rotary electric machine is controlled so as to coincide with a target rotational speed by adding correction torque to the target torque; and the control device executes the hydraulic pressure regulation control on the basis of the required drive force and the correction torque for the rotational speed feedback control.
