Abstract: The present disclosure provides a driving control method for hybrid type vehicles with a DCT. The method includes: receiving the motor speed from a driving motor; when abnormality of the motor speed is detected, requesting driving of an engine and determining whether an engine clutch is engaged; if it is determined that the engine clutch is released, controlling a clutch of a current driving stage using a clutch torque higher than a transmission input torque; controlling the current driving stage to be a limp home driving stage set in advance to be in a limp home driven status.

Abstract: A method of preventing a vehicle clutch from sticking includes a wear compensation actuation step of actuating a wear compensation device in conjunction with engagement actuation of a clutch actuator after an ignition is turned off when an actuation condition of the wear compensation device is satisfied, and a clutch control step of controlling a clutch position so that the clutch position returns to a disengaged state of the clutch actuator by reactuating the wear compensation device, when a clutch position based on an amount of variation in an actuation length of the actuation rod fails to return to the disengaged state of the clutch actuator during returning of the engaged clutch actuator.

Abstract: A shift control method in a vehicle having a dual clutch transmission may include determining whether power-off downshifting is being carried out, monitoring whether a tip-in is caused by a driver during the power-off downshifting, releasing all of a transmission torque of a releasing clutch and a transmission torque of a coupling clutch if it is determined that the tip-in is caused during the power-off downshifting, decreasing an engine torque at a point of time when an engine speed becomes identical to a speed of a coupling input shaft on which a target gear is disposed, and synchronously increasing the engine torque by gradually increasing the transmission torque of the coupling clutch and gradually reducing an amount by which the engine torque is decreased when the releasing clutch has completed a releasing action and the engine speed becomes faster than the speed of the coupling input shaft.

Abstract: The present disclosure provides a control method for a vehicle with a DCT, the method including: a diagnosing step of disengaging a corresponding clutch and limiting engine torque to suppress an increase in engine RPM when a controller detects an error from a hall sensor signal, and then applying a test pulse for diagnosing the hall sensor; a reset attempting step of attempting to reset the clutch to an initial position when the controller determines that the hall sensor signal is normal after the diagnosing step; and a returning step of starting normal control of the clutch from the initial position to a target clutch stroke by means of the controller and of removing the limiting of the engine torque, when the clutch is reset to the initial position in the reset attempting step.
