摘要: 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.

摘要: A control method of a hybrid vehicle includes: confirming whether or not the driving mode of the vehicle is an EV mode when a controller senses shift of the position of a shift lever from the position R to the position D or from the position D to the position R; applying reverse-directional motor torque to a motor through the controller so that a motor speed is synchronized with the speed of an engagement-side clutch, as a result of confirmation of the driving mode, if the driving mode of the vehicle is the EV mode; and executing normal driving of the vehicle by applying regular-directional motor torque to the motor through the controller after synchronization of the motor speed with the engagement-side clutch speed.

摘要: Disclosed is a method of diagnosing a malfunction in a dual clutch transmission (DCT) attributable to a gear synchromesh failure, without an output shaft speed sensor. The method includes: calculating, a difference (referred to as a first difference) between a first input shaft speed and the product of a wheel speed and a first gear ratio; a difference (referred to as a second difference) between a second input shaft speed and the product of a wheel speed and a second gear ratio; diagnosing a first input shaft as having a transmission gear synchromesh failure when the first difference is greater than a first reference value and the second difference is equal to or smaller than a second reference value; and performing control such that a gear shifting operation is performed using only a second input shaft when the first input shaft is diagnosed as having a transmission gear synchromesh failure.

摘要: 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.
