Abstract: The present disclosure provides a control method for a vehicle with a DCT, the method including: a diagnosing step of disengaging a corresponding clutch and limiting engine torque to suppress an increase in engine RPM when a controller detects an error from a hall sensor signal, and then applying a test pulse for diagnosing the hall sensor; a reset attempting step of attempting to reset the clutch to an initial position when the controller determines that the hall sensor signal is normal after the diagnosing step; and a returning step of starting normal control of the clutch from the initial position to a target clutch stroke by means of the controller and of removing the limiting of the engine torque, when the clutch is reset to the initial position in the reset attempting step.

Abstract: A diagnostic method of determining clutch failure of a dual clutch transmission (DCT) includes comparing, by a controller, a wheel torque of a vehicle with a driving load torque of the vehicle, confirming, by the controller, whether or not the vehicle is driving, if, as a result of comparing step, the wheel torque is greater than the driving load torque, releasing, by the controller, a gear engaged with a non-drive shaft, if, as a result of the confirming step, the vehicle is in a stopped state, reconfirming, by the controller, whether or not the vehicle is driving, after the releasing step, and judging, by the controller, that a transmission clutch of the non-drive shaft fails, if, as a result of the reconfirming step, the vehicle is driving.

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.
