PURPOSE: A method of learning control is provided to complete control of gearshift for the target gearshift stage without shock of gearshift during gearshift. CONSTITUTION: A method of learning control consists of a step judging necessity of synthetic control for decreasing output of an engine when a car is driven and gearshift is performed; a step outputting a required signal of the synthetic control for decreasing output of the engine to a controlling device of an engine; a step judging output of a finishing signal of synthetic control in the controlling device of the engine; a step producing new time difference value(T) as operating last value(Tx) in the value(Ta) by fixed arithmetic formula as inputting time from the end point (ERP) of synthetic control to point of the gearshift finish(S.F) after inputting time from the last end point of synthetic control to point of the gearshift finish; a step judging if new producing time difference value is larger than the voluntary fixed the standard time value as operating last time value and the time value; a step returning to the first step after a new end point Tx produces as subtracting the fixed standard time value from time, from the last end point of synthetic control to time of the S.F point, and performs learning storage to apply the value to the next if a producing new time difference value is larger than a voluntary fixed standard time value. By selecting proper time of synthetic control according to the learning stored value, the control of gearshift is performed and durability of a clutch is improved.
