Abstract:
A control apparatus for an automatic transmission, comprising:oil pressure control means for controlling engagement transition oil pressure which is supplied to friction engaging elements so that a parameter changed by a speed-change is changed along a locus of a predetermined target value;engine torque control means for controlling a quantity of change in engine output torque during a speed-change so that a parameter whose value changes in parallel to a speed changing operation has an optimum change characteristic;oil pressure correction means for correcting said engagement transition oil pressure, based on the quantity of change in said engine output torque, in controlling said engagement transition oil pressure; andengine torque correction means for correcting the quantity of change in said engine output torque, based on said engagement transition oil pressure, in controlling the quantity of change in said engine output torque.
