CONTROL DEVICE FOR AUTOMATIC TRANSMISSION

摘要

PURPOSE: To accurately detect the stable state of a rotating speed change rate for the start of feedback control at the time of speed change. CONSTITUTION: A control device for an automatic transmission executes the speed change of the automatic transmission 2 connected to an engine 1 by increasing the engaging pressure of a specified friction engaging device 3, and performs the feedback control of the engaging pressure of the friction engaging device 3 so that the rotating speed of a specified rotary element 4 becomes the predetermined target rotating speed when the rotation change state of the rotary element 4 generated in association with the rise of the engaging pressure of the friction engaging device 3 becomes a specified stable state. This control device is provided with an output detecting means 5 for detecting the output of the engine 1, and a target stable state setting means 6 for setting a stable state according to engine output detected by the output detecting means 5.
