  • Patent number: 10384666
    Abstract: Disclosed herein is a technique for improving drivability of a vehicle by controlling the driving of the vehicle by a double clutch when the clutch of a double clutch transmission (DCT) is overheated. There is provided a shift control method for a hybrid vehicle with a DCT. In particular, where it is desired to perform shifting when one of clutches of the DCT is overheated, double-clutch shifting is performed using a non-overheated clutch and an engine clutch without using the overheated clutch, thereby reducing disharmonic shifting in virtue of a small difference in gear ratio during shifting and improving shifting and driving performance.

  • Patent number: 10316906
    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.
