Abstract
A method for learning a touch point of a clutch in a Dual Clutch Transmission (DCT) vehicle includes a synchronization determination step, a drive shaft slip inducement step in which the controller induces a clutch of the drive shaft to slip, a non-drive shaft torque application step in which the controller applies torque to a clutch of the non-drive shaft, and a touch point learning step in which, while the speed of the non-drive input shaft follows the engine speed in the non-drive shaft torque application step, the controller searches for a certain point at which the speed of the non-drive input shaft changes and differs from the speed of the drive input shaft, and learns the point as the touch point of the clutch of the non-drive shaft.
