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： 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.
