Control apparatus and control method for an automatic transmission, program for directing a computer to execute the control method, and storage medium on which program is recorded

A control apparatus of an automatic transmission that establishes a gear speed by engaging a friction engagement element that is operated by hydraulic pressure, the control apparatus comprising:

• a hydraulic pressure controlling portion that controls hydraulic pressure supplied to the friction engagement element;
• a determining portion that determines whether a correction of the hydraulic pressure supplied to the friction engagement element during a gear shift is allowed based on a target input torque to be input to the automatic transmission during the gear shift and a torque that corresponds to an actual input torque to be actually input to the automatic transmission;
• and
• a hydraulic pressure correcting portion that corrects the hydraulic pressure based on a state of the automatic transmission during the gear shift when the determining portion determines that the correction is allowed, wherein
• the determining portion allows the correction when a value obtained by integrating a difference between the target input torque and the torque that corresponds to the actual input torque over a predetermined period of time is equal to or less than a predetermined value.
