Abstract: PURPOSE: A gearshift control method prevents shock generated as the rotation frequency of an engine suddenly increases on mode switching by tip-in. CONSTITUTION: A gearshift control method comprises four steps. The first step(S200) is to detect whether tip-in occurs by the sudden acceleration signal during lean burn mode driving. The second step(S300, S400) is to increase the initial throttle voltage by the very small set value to induce the engine rotation frequency(Ne) to increase when the sudden acceleration signal is detected. The third step(S500) is to determine whether the difference between the engine rotation frequency(Ne) and the turbine rotation frequency(Nt) is larger than a standard value. The fourth step(S600) is to switch from the lean burn mode to the normal mode if the difference between the engine rotation frequency(Ne) and the turbine rotation frequency(Nt) is larger than the standard value.
