Abstract: Disclosed is a downshift control method for a hybrid DCT vehicle. The method includes: determining, by a controller, whether a downshift is desired while a vehicle travels on a slope having equal to or more than a predetermined reference gradient; comparing, by the controller, a motor speed with a desired shift stage input shaft speed, and selectively performing either a forward control step of increasing a motor torque in a forward direction to increase the motor speed in the forward direction or a negative control step of increasing the motor torque in a negative direction to increase the motor speed in the negative direction. Thus, it is possible to reduce the backward sliding of the vehicle by suppressing the motor speed from unnecessarily increasing and rapidly finishing the downshift.

Abstract: A shift control method for a DCT vehicle, which adjusts a time required to shift gears through clutch control in a DCT. The shift control method includes controlling a release-side dutch such that the release-side dutch is partially disengaged by a controller when gear shifting is initiated in a state in which an accelerator pedal is not pressed, performing synchronization control by partially applying an apply-side dutch torque in an initial stage of synchronization such that an engine rotational speed follows and synchronizes an apply-side input shaft speed, and partially applying a release-side dutch torque in a last stage of synchronization by the controller, and performing torque hand-over control such that an apply-side clutch is engaged while the release-side clutch is disengaged by the controller, after performing the synchronization control.

Abstract: A method of controlling a clutch of a vehicle, by which the clutch can be controlled to reduce jerking impacts in the case of a sudden behavior in engine torque. An amount of APS opening and engine torque are received while the vehicle is cruising using driving force from an engine. When the amount of APS opening is smaller than a first reference value, the clutch is controlled to slip by controlling clutch torque to be smaller than engine torque. After controlling the clutch slip, when the engine acts as a load while the vehicle is cruising, the clutch is engaged by application of the clutch torque to the clutch.
