A control device of a vehicle drive device in which an output of a power source is input from a hydraulic power transmission device via a friction engagement device to a continuously variable transmission and transmitted toward drive wheels after speed is changed by the continuously variable transmission, the control device includes: an abnormality detecting portion configured to make a determination of abnormality indicating that the friction engagement device is in a complete release state or a slip state; and an abnormality distinguishing portion, if the abnormality detecting portion makes a determination of abnormality, configured to judge that the friction engagement device is in the slip state when an input/output rotation speed difference between an input rotation speed and an output rotation speed of the hydraulic power transmission device is equal to or greater than a predetermined slip determination value and that the friction engagement device is in the complete release state when the input/output rotation speed difference is less than the slip determination value. |
