Method of controlling 6 - shift in an automatic transmission for vehicles

But achieve a 6 accelerated by using a conventional five speed power train, the shift control is easy, and improve byeonsokgam to the optimum gear ratio of fuel consumption and power performance improvements, and to minimize the impact of the transmission and, for the purpose of contributing to weight reduction; As two single-pinion planetary gear set, formed of the peripheral sokbu and hook-up to the three clutches and two brakes, one way clutch; A single pinion planetary gear sets, but the shift control of the power train of a vehicle automatic transmission as set comprising a part made of a hook-up speed to the clutch, brake and one-way clutches for each one by one, The peripheral sokbu in forward first, second deceleration having a predetermined gear ratio in the, forward third speed increasing in dongsok, 4F in, speed-increasing in the same dongsok, advancing 6 and in the third, such as in the 4 in advance 5 is output to the state, In the sub-transmission portion controlled so as to output dongsok in deceleration, forward 5, 6 in the forward and fourth sequential up / down shift and a 6th speed shift of the plurality of the vehicle automatic transmission skip shift is made It provides a control method.
