Disclosed are a shifting time and damper clutch control method for a full throttle state, and an automatic transmission for a vehicle controlled thereby. According to an embodiment of the present invention, the shifting time and damper clutch control method for a full throttle state comprises: a shifting point correction logic entry condition determination step a) of, when an engine of a driving vehicle is in a full throttle driving state, determining whether a shifting point correction logic entry condition is satisfied or not; an engine speed calculation step b) of, when the shifting point correction logic entry condition is satisfied, calculating the highest expected engine speed during shifting; a shifting time delay step c-1) of delaying the shifting time for a certain period of time when the highest expected engine speed value acquired by the engine speed calculation step is under a preset value; a damper clutch control entry condition determination step d) of determining whether a damper clutch control entry condition is satisfied or not when the engine of the driving vehicle is in the full throttle driving state; and a damper clutch closing step e-1) of closing the damper clutch when the damper clutch control entry condition is satisfied and the control for delaying the shifting time is working, and when a damper clutch closing condition is satisfied. The shifting time and damper clutch control method for a full throttle state and an automatic transmission for a vehicle controlled thereby can improve the acceleration performance and reduce the delay in acceleration in a full throttle state. 풀 스로틀 시 변속시점 및 댐퍼클러치 제어방법 및 이를 통해 제어되는 차량용 자동 변속기가 개시된다. 본 발명의 실시 예에 따른 풀 스로틀 시 변속시점 및 댐퍼클러치 제어방법은, a) 주행중인 차량의 엔진이 풀 스로틀 구동 상태에서, 변속점 보정 로직 진입조건을 만족하는지를 판단하는 변속점 보정 로직 진입조건 판별단계, b) 변속점 보정 로직 진입조건 만족 시 변속 중 예상 최대 엔진 속도를 계산하는 엔진속도 계산단계, c-1) 엔진속도 계산단계를 통해 획득된 예상 최대 엔진 속도값이 기설정된 값 미만일 경우, 소정 시간 동안 변속시점을 지연시키는 변속시점 지연단계, d) 주행중인 차량의 엔진이 풀 스로틀 구동 상태에서, 댐퍼클러치 제어 진입조건을 만족하는지를 판단하는 댐퍼클러치 제어 진입조건 판별단계 및 e-1) 댐퍼클러치 제어 진입조건을 만족하고, 변속시점을 지연시키는 제어가 실행중인 경우, 댐퍼클러치 클로즈 조건을 충족하면 댐퍼클러치를 클로즈(Close)시키는 댐퍼클러치 클로즈 단계를 포함하는 것을 구성의 요지로 한다.
