Patent ID: 8668621

Claim:
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, the control device configured to execute, when a transition is made from a state in which a drive force is transferred between the rotary electric machine and the wheels with the first friction engagement device in a disengaged state and with the second friction engagement device in an engaged state to a state in which a drive force is transferred between the internal combustion engine and the wheels with the first friction engagement device in an engaged state, 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.
