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.

A method of searching for a sync start in an automated manual transmission, may include a slip preparing step of operating, in a parked position, a sleeve and a clutch restrained so as not to rotate into a slip state, an actuator operating step of moving the sleeve toward a clutch gear from a neutral position, a clutch speed determination step of determining whether or not a speed of rotation of the clutch has decreased by the actuator operating step, a stop determination step of determining whether or not a movement of the sleeve that was driven by the actuator operating step has stopped, and a first position determination step of determining a point where the clutch speed determination step determines that the speed of the rotation of the clutch has decreased and the stop determination step determines that the movement of the sleeve has stopped as the sync start.
Abstract:
A touch point searching method contributes to improving shift feel and durability of a clutch by making it possible to search and set more accurately a touch point in consideration of drag torque of an input shaft connected with the clutch such that the clutch can be more appropriately controlled.
