PROBLEM TO BE SOLVED: To provide a control device for an automatic transmission to making shifting with re-setting of a frictional engagement element whereby the controlling stability and responsiveness of the input shaft revolving speed at shifting are enhanced. SOLUTION: The target turbine revolving speed Tgt#Nt at shifting is subjected to a delay processing to obtain a normal model target Tgt#Nt#kihan, while the target turbine revolving speed Tgt#Nt is subjected to an advance processing to obtain an inverted filter target speed Tgt#Nt#Inverse. The value obtained by subtracting the target turbine revolving speed Tgt#Nt from the inverted filter output Tgt#Nt#Inverse is used as a feedforward correction revolving speed FF#Nt, while feedback correction revolving speed FB#Nt is calculated from the deviation of the actual turbine revolving speed r#Nt from the normal model target Tgt#Nt#kihan, and the sum thereof is converted into a torque and the feedback correction torque TFB is determined, and the oil pressure on the engagement side is corrected with the feedback correction torque TFB. |
