    摘要： [Solution] It is an object to provide a control apparatus for an automatic transmission which prevents a worsening of a driving feeling and a generation of a one way clutch engagement shock when an accelerator is again depressed after an accelerator foot separation while a rotation speed of a driving source is maintained at a high rotation speed. An engine and the automatic transmission is equipped. A gear-shift control for the automatic transmission (AT) is performed according to a position of a driving point (VSP, APO) present in a gear-shift map. When a gear-shift line correction request occurs, gear-shift line correction control means is provided for correcting up-shift lines and down-shift lines in the gear-shift map by vehicle speed correction lines L0(u), L0(d) set toward a higher vehicle speed than those gear-shift lines before the correction. The gear-shift line correction control means adds a gear-shift line correction such that a correction quantity toward a higher vehicle speed side in a small accelerator opening angle area is made smaller than another correction quantity toward the higher vehicle speed side in a large accelerator opening angle area whose accelerator opening angle is larger than the small accelerator opening angle area to the up-shift lines of the gear-shift stages at each of which a one way clutch is engaged during a drive from among the gear-shift lines after a vehicle speed correction.
