Abstract:
1. A control device to control a stepped transmission mechanism of a transmission, the stepped transmission mechanism including a first clutch to be engaged at startup and a second clutch that differs from the first clutch, and is interlocked when a hydraulic pressure is supplied to the first clutch and the second clutch and the first and second clutches are completely engaged, comprising: a hydraulic pressure control unit configured to control a hydraulic pressure supplied to the stepped transmission mechanism such 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 a case of a return from an idle stop control in which an engine is automatically stopped, wherein the hydraulic pressure control unit is configured to start reducing the hydraulic pressure supplied to the second clutch when an increased amount of an engine rotation speed per unit time becomes smaller than a predetermined increased value, wherein the predetermined increased value is a value at which a rev-up of the engine, in which the increased amount of the engine rotation speed per unit time is positive, can be determined to end, and wherein the first and second clutches are completely engaged during interlock of the stepped transmission mechanism.
