    摘要: A method of diagnosing a malfunction in a dual clutch transmission may include determining, by a controller, a difference between a first input speed and a wheel speed output by reflecting a transmission gear ratio on the first input speed, and determining by the controller, a difference between a second input speed and a wheel speed output by reflecting the transmission gear ratio on the second input speed, when the difference between the first input speed and the wheel speed output by reflecting the transmission gear ratio on the first input speed is greater than a first reference value and the difference between the second input speed and the wheel speed output by reflecting the transmission gear ratio on the second input speed is equal to or smaller than a second reference value, diagnosing a first input shaft as having a transmission gear synchromesh failure.

    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: 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.
