    摘要: A shift control method for a dual clutch transmission (DCT) vehicle may include, performed by a controller of the DCT, an actual shift determining step, a cooperation control termination determining step, a flare determining step, an engine torque reducing step, a torque adding step, an engine torque raising step, and a shift finishing step of reducing an amount of reduction of the engine torque until synchronization is completed in proportion to a synchronization prediction time in which it takes an engine speed to reach a synchronization speed when the synchronization prediction time is smaller than a reference time during which the torque adding step and the engine torque raising step are performed, and having slip control over an engagement-side clutch.

    摘要: 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.
