Abstract: A method for controlling vehicle creep driving includes learning, by a controller, a touch point of a clutch when a condition for creep driving is satisfied, changing, by the controller, an upper limit of a creep clutch torque, which is set as a permissible maximum torque of the clutch during creep driving, depending on the learned touch point, and controlling, by the controller, creep driving such that the creep clutch torque required for creep driving is set to be equal to or less than the changed upper limit of the creep clutch torque, and the creep clutch torque is output.

Abstract: A shifting control method for a vehicle with a Double Clutch Transmission (DCT), may include determining whether a manual range power-on up shift has been started, determining whether an actual shifting period has been started, when the manual range power-on up shift has been started, and applying additional predetermined compensation torque to basic torque applied to an engagement-side clutch, when the actual shifting period has been started.

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.

Abstract: An engine torque control method for a vehicle according to the present disclosure includes: sensing an engagement state of a clutch of the vehicle; calculating a slip index according to engine torque, engine revolutions per minute (RPM), clutch torque, and clutch RPM; and filter-controlling the engine torque based on the calculated slip index and the sensed engagement state of the clutch.

Abstract: A method of adjusting clutch characteristics of a Double Clutch Transmission (DCT) vehicle may include determining whether gear shifting has been initiated, updating a T-S curve of a release-side clutch by a transmission torque that is determined using an equation of motion of an engine and a clutch, when a condition in which a difference between an engine speed and a speed of a release-side input shaft is satisfied to be above a first predetermined reference value during a first reference period of time when the gear shifting is determined to have been initiated, and when a torque handover has not been initiated, updating the T-S curve of a connection-side clutch by the transmission torque that has been determined using the equation of motion during a period of time from completion of torque handover to completion of the shifting of gears.

Abstract: The present disclosure relates to a method and apparatus for learning a clutch torque of a Dual Clutch Transmission (DCT) The method includes judging whether shifting begins, controlling torque transmission of a coupling-side clutch and a release-side clutch to cross each other while following a coupling-side target clutch torque when shifting begins, and detecting and storing a learning value, after the controlling has begun, using a function determined by the relationship between an average value of an engine angular acceleration and a coupling-side shifter input-shaft angular acceleration, engine rotation inertia, and a torque compensated by slip control of the coupling-side clutch.

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.
