And outputting a corresponding control signal for traveling at the current throttle and the shift stage, when the fuel efficiency and the displacement are more efficient in the driving state than the value obtained by evaluating (X2) the shift speed control method of the automatic transmission. 청구항 4에 있어서, 현재의 스로틀과 변속단, 엔진의 RPM(Ne)에 의해 연산되어 평가(X1)된 값보다 변속단을 인접 변속단으로 변속후 현 차속을 유지하기 위한 스로틀 개도량(Th)을 연산하여 연비와 배기량을 평가(X2)한 값이 주행상태에 있어서 효율적인 경우, 스로틀 개도를 보정하여 새로운 스로틀 개도와 새로운 변속단을 설정하여 주행 도로상태에 따라 해당하는 스로틀 보정 신호 및 변속 동기 신호를 출력하고, 스로틀 개도만을 보정하여 새로운 스로틀 개도 제어 신호만 출력하는 것을 포함하여 이루어진 자동 변속기의 변속 제어 방법.The throttle opening amount Th for maintaining the current vehicle speed after shifting the shift stage to the adjacent shift stage is calculated by the current throttle, the shift stage, and the engine RPM (Ne). If the value of the fuel economy and the exhaust capacity (X2) is calculated in the driving state is effective in the driving state, the throttle opening degree is corrected to set a new throttle opening degree and a new shift stage, so that the throttle correction signal and the shift synchronization signal corresponding to the driving road condition are And outputting only the new throttle opening degree control signal by correcting only the throttle opening degree. 청구항 4에 있어서, 운전자가 설정한 차속(No1)과 차량의 현재 주행차속(No2)이 같은 경우, 현재의 스로틀과 변속단으로 주행하기 위한 해당 제어 신호를 출력하는 것을 포함하여 이루어진 자동 변속기의 변속 제어 방법.5. The shift of the automatic transmission according to claim 4, wherein, when the vehicle speed No1 set by the driver and the current traveling vehicle speed No2 of the vehicle are the same, a corresponding control signal for driving at the current throttle and the shift stage is output. Control method.
