Abstract
A control device controls a transmission mechanism which includes a first clutch to be engaged at startup and a second clutch, and is interlocked when hydraulic pressure is supplied to the first and second clutches and when the first and second clutches are completely engaged. The control device includes a hydraulic pressure control unit controlling hydraulic pressure supplied to the transmission mechanism so that the first clutch is set in a completely engaged state and the second clutch is set in a slip interlock state where the second clutch is not completely engaged in the case of a return from an idle stop control in which an engine is automatically stopped. The hydraulic pressure control unit starts reducing hydraulic pressure supplied to the second clutch when an increased amount of an engine rotation speed per unit time becomes smaller than a predetermined value.
