Abstract
A method for learning a touch point of a transmission is disclosed. The method may include: moving a sleeve of a synchronizing device in a shift stage gear direction and calculating a predicted rotation speed based on an initial rotation speed and a rotation speed change rate of a transmission clutch; positioning a first point when a difference between an actual rotation speed and the predicted rotation speed occurs and positioning a second point when a difference value between the actual rotation speed and the predicted rotation speed reaches a set speed; calculating a determination time by subtracting a second time to move the sleeve from the first point to the second point from a first time to move the sleeve from the first point to a pre-stored touch point; and performing a correction and control on the touch point based on the determination time.
