A method for learning a characteristic of a clutch in a DCT vehicle includes a shifting condition determination step for determining whether a shifting condition is satisfied, a synchronization step for partly reducing torque of a disengagement-side clutch in order to synchronize an engine speed with a speed of an engagement-side input shaft when shifting is started when the shifting condition is satisfied, a clutch release determination step for determining whether a slip amount of a disengagement-side clutch exceeds a reference slip amount, and a disengagement-side clutch learning step for updating clutch torque on a characteristic curve of the disengagement-side clutch using the torque of the disengagement-side clutch that is controlled to allow the slip amount of the disengagement-side clutch to exceed the reference slip amount in the clutch release determination step, and for learning the updated clutch torque.

The present disclosure provides a method of learning and controlling a transmission that includes: a learning condition-checking step of checking whether there is a need for learning by comparing information about a vehicle collected from parts of the vehicle by a detector and transmitted to a controller with reference values kept in the controller; a slip amount-comparing step of comparing an actual slip amount of a damper clutch with a nominal slip amount inputted in advance in the controller, when the learning condition-checking step determines that there is a need for learning; and a learning step of performing learning as according to a learning value table inputted in advance in the controller on the basis of a result obtained by the controller in the slip amount-comparing step.
