Abstract
A control device that controls a vehicle drive device, including a rotary electric machine and internal combustion engine that drive wheels, a first friction engagement device and a second friction engagement device. The control device is configured to execute rotational state control in which a rotational state of the rotary electric machine is controlled so as to establish a target rotational state with the second friction engagement device in a slip engagement state, and hydraulic pressure regulation control in which a hydraulic pressure supplied to the second friction engagement device is controlled on the basis of torque of the rotary electric machine produced during the rotational state control after the first friction engagement device is transitioned to a direct engagement state while the second friction engagement device is transitioned from the slip engagement state to a direct engagement state.
