CONTROL DEVICE FOR AUTOMATIC TRANSMISSION

摘要

An ECU executes a program including a step (S108) of causing a B2 brake to enter an engaged state, when first gear is implemented (YES in S100) and when a difference between an output shaft rotation speed NOUT (1) estimated from an input shaft rotation speed NIN and a detected output shaft rotation speed NOUT (2) is greater than a threshold value N(0) (YES in S 106). When the B2 brake enters the engaged state, the relative rotation between the inner race and the outer race of a one-way clutch is limited.
