Abstract
A control device () for a stepped transmission mechanism is configured to perform an interlock by engaging a first clutch () and increasing hydraulic pressure of a second clutch () up to a first predetermined pressure (P) such that an output shaft of the transmission mechanism is fixed, after an idle-stop condition including at least a requirement that a vehicle is stationary was satisfied and before a stop of an engine (). The control device includes a gradient detecting section () that detects a gradient (R) of a road surface on which the vehicle is stationary; and a hydraulic control section () that performs a slipping interlock by reducing the hydraulic pressure to a second predetermined pressure (P), if the gradient R detected by the gradient detecting section is lower than or equal to a predetermined value (R) during the interlock and before the stop of the engine.
