A control device for controlling a vehicle drive unit including an input member drivingly connected to an engine; an output member drivingly connected to a wheel; and a transmission device that includes engagement elements, that switches between shift speeds by control of engagement and disengagement of engagement elements, and that transmits a rotational driving force of the input member to the output member at a speed changed at a speed ratio of each of the shift speeds. The control device includes a control unit that controls the transmission device to achieve a one-way transmission speed in a running idle state in which a vehicle is running while the rotational driving force of the input member is not transmitted to the output member and a rotational speed of the engine is controlled to a predetermined idle speed. The transmission device has, as one of the shift speeds, the one-way transmission speed at which the rotational driving force from the input member to the output member is transmitted but the rotational driving force from the output member to the input member is not transmitted.
