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.

Abstract: A shift control method includes: a step for confirming whether a high rank shift order is made during a take up control; a step for determining whether a difference between rotation number of an input shaft and the rotation number of the engine is within a predetermined reference rotation number when a high rank shift order has been made as a result of the shift order confirming step; and a step for ending the take up control and converting it into a shift control when the difference between rotation numbers of the input shaft and the engine has been within a predetermined reference rotation number as a result of the slip determining step. Even when a high rank shift order is made, the reduction of the shift replying property and shift feeling can be minimized to improve riding feeling and durability of the first and second clutches.

Abstract: The present disclosure provides technology for preventing burst of a clutch under the driving circumstance, which enters into a road surface with a high friction coefficient after passing through a road surface with a low friction coefficient in vehicle driving; and the present disclosure determines if a wheel-lock has occurred in driving based on a factor reflecting a driving status of the vehicle; upon determining occurrence of the wheel-lock, in the case that a vehicle speed rapidly increases and a difference value between a transmission input shaft speed and an engine speed, which form a current driving gear, is larger than a set value, blocks a mechanical engagement between a clutch and a wheel, which form the current driving gear.

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.

Abstract: Disclosed is a method of diagnosing a malfunction in a dual clutch transmission (DCT) attributable to a gear synchromesh failure, without an output shaft speed sensor. The method includes: calculating, a difference (referred to as a first difference) between a first input shaft speed and the product of a wheel speed and a first gear ratio; a difference (referred to as a second difference) between a second input shaft speed and the product of a wheel speed and a second gear ratio; diagnosing a first input shaft as having a transmission gear synchromesh failure when the first difference is greater than a first reference value and the second difference is equal to or smaller than a second reference value; and performing control such that a gear shifting operation is performed using only a second input shaft when the first input shaft is diagnosed as having a transmission gear synchromesh failure.
