変速機の制御装置。[Scope of Claim for Utility Model Registration] In a control device for an automatic transmission that automatically performs a clutch operation and a gear shift operation depending on the vehicle speed, an engine brake operation detection means is provided to detect when the engine brake is activated. In addition, when the engine brake is operating, the shift operation is suppressed until the vehicle speed decreases to a predetermined speed, based on the switching vehicle speed that is set to the lower speed side than the switching vehicle speed of the gear shift when the engine brake is not operating. A control device for an automatic transmission, comprising an engine brake operation control means for controlling a gear shift operation.
