<p>Disclosed is a gear shift control method of an automatic transmission. The gear shift control method capable of controlling a gear to be shifted from a current step realized by the engagement of a first, a second, and a third friction element to a target step realized by the engagement of a fourth, a fifth, and a sixth friction element comprises: a step of shifting the gear to the current step by additionally engaging a surplus friction element among the fourth, the fifth, and the sixth friction element at the end of shifting the gear to the current step; a step of step-releasing one of the surplus friction element and the first, the second, and the third friction element at a start timing of a gear shift according to the target step when shifting the gear from the current step to the target step; and a step of controlling the gear to be shifted to the target step after step-releasing the friction element. According to the present invention, the gear shift control method is capable of reducing control elements in the case of shifting the gear to the target step by additionally engaging the surplus friction element when shifting the gear to the current step, thereby performing a skip-shift.</p> |
