Abstract: A shift control method includes: a step for confirming whether a high rank shift order is made during a take up control; a step for determining whether a difference between rotation number of an input shaft and the rotation number of the engine is within a predetermined reference rotation number when a high rank shift order has been made as a result of the shift order confirming step; and a step for ending the take up control and converting it into a shift control when the difference between rotation numbers of the input shaft and the engine has been within a predetermined reference rotation number as a result of the slip determining step. Even when a high rank shift order is made, the reduction of the shift replying property and shift feeling can be minimized to improve riding feeling and durability of the first and second clutches.

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.
