Abstract: A method of estimating transmission torque of a vehicle dry clutch may suitably estimate a variation in the characteristics of transmission torque relative to the actuator stroke of a dry clutch even during the driving of a vehicle, so that the dry clutch is more suitably controlled. In the method of estimating transmission torque of a dry clutch, a clutch is released so that a slip of the clutch occurs. If the slip of the clutch has occurred, the slip of the clutch is uniformly maintained. If the slip of the clutch is uniformly maintained, a relationship between a stroke of an actuator of the clutch and transmission torque of the clutch is determined from a relationship between the stroke of the actuator and torque of an engine in the uniformly maintained slip state.

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.

Abstract: A method and an apparatus for controlling a clutch of a vehicle include determining whether a vehicle is moving under a condition in which a gearshift is coupled to the clutch. A clutch torque is learned in which the clutch is maintained in a micro-slip state by decreasing a target clutch torque for a corresponding gear level when it is determined that the vehicle is moving under the condition in which the gearshift is coupled to the clutch. Learning reliability is calculated by reflecting a difference between an engine torque and clutch torque. The clutch is maintained in the micro-slip state for the clutch torque learning or converting the clutch into a lock-up state, depending on a learning reliability level.
