Control Device For Automatic Transmission

摘要

ECU executes a program including the step (S 108 ) of setting a B 2 brake to a engaging state when a first speed gear is effected (YES at S 100 ) and when the difference between an output shaft rotation speed NOUT ( 1 ) estimated from an input shaft rotation speed NIN and the detected output shaft rotation speed NOUT ( 2 ) is larger than a threshold N ( 0 ) (YES at S 106 ). When the B 2 brake is in an engaged state, the relative rotation between the inner race and the outer race of one-way clutch is limited.
