An object of the present invention provides a control system for the automatic transmission that can suppress, downshift when, by setting the start timing of the increase in the transmission torque control, as appropriate, the occurrence of shift shock due to pull while suppressing the generation of the recover shock to.
In the automatic transmission (AT) to achieve a plurality of speed change stages by switching the fastening state of the friction element in order to transmit torque from the engine (Eng) to the drive wheels, during the downshifting of the current time, yarn deviation state of the physical quantity and the target physical quantity of the base to the car during step to learn correct the signed command pressure of the friction element upon meeting downshift S1 and a downshift, the shift transition a, when a start expected timing of a preset torque phase by the time control, the engine (Eng ) fuel recover control of the torque temporarily increases in the step S3 of performing of, when shift-pressure learning correction is prohibited the torque increase control until it is determined that there is convergence, the shift-pressure learning correction is determined that the convergence of the torque increase control It was provided with a permission learning convergence judgment step of S2.
