Provided is a vehicle drive device control device such that, when a first engaging device (CL1) is controlled in a sliding engagement state, a decrease in torque transmitted to a wheel (W) in the event of an increase of the temperature of an engaging member of the first engaging device (CL1) is suppressed, while a temperature increase of the engaging member is suppressed. The control device is provided with: a first engagement slide control unit that controls a second engaging device (CL2) to a direct-connection engagement state during a rotating operation of an internal combustion engine (E), and that controls the first engaging device (CL1) to the sliding engagement state; and a temperature increase suppressing control unit that causes an output torque of a rotating electrical machine (MG) to be increased while causing a transmission torque of the first engaging device (CL1) to be decreased when the temperature of the first engaging device (CL1) is increased during first engagement slide control.
