Abstract

A control device for a vehicle drive device includes performing neutral travel control in which disengagement/engagement elements are disengaged with the wheels rotating so the state of a speed change mechanism is controlled into a neutral state where transfer of a drive force between the input member to the engine and the output member to the wheels is not performed, and the wheels are driven by a rotary electric machine drive force; and comparing an operating state value of each of target actuators that control the state of the disengagement/engagement elements, and a determination value so torque from the speed change mechanism to the wheels because of torque transferred by each of the disengagement/engagement elements, falls within an allowable range during neutral travel control, and determines whether the torque transferred from the speed change mechanism to the wheels falls within the allowable range.
