Abstract
Official abstract text for this publication.
A device for controlling an automatic transmission includes: a position detection means for detecting a shift position; a vehicle speed detection means for detecting a vehicle speed; a rotation frequency detection means for detecting an input rotation frequency of the automatic transmission; and a control means for, when the shift position has been switched from a parking position or a neutral position to a driving position, making a determination about switching from stopped-state control to running-state control based on the vehicle speed after a physical amount indicating a state of the automatic transmission becomes equal to or larger than a predetermined value, the stopped-state control being control for a hydraulic pressure supplied to engaging elements based on the input rotation frequency of the automatic transmission, and the running-state control being control for the hydraulic pressure supplied to the engaging elements without using the input rotation frequency of the automatic transmission.
