Clutch control method and clutch control filter for vehicle

A clutch control method, comprising:

• a variation setting step of setting, by a controller, a current torque variation depending on a difference between a just previous clutch control torque and a clutch target torque;
• a limit determining step of determining, by the controller, whether a jerk of a clutch control torque need not be limited when the clutch control torque is reduced and then is increased or when the clutch control torque is continuously reduced by using the current torque variation and a just previous torque variation;
• when the jerk of the clutch control torque need not be limited as a result of performing the limit determining step, a direction setting step of determining, by the controller, the current torque variation set in the variation setting step as a final torque variation;
• when the jerk of the clutch control torque needs to be limited as a result of performing the limit determining step, a limit setting step of determining the current torque variation as the final torque variation by limiting, by the controller, the current torque variation to an upper bound of the jerk that is a limit in which a variation of the clutch control torque is increased and a lower bound of the jerk that is a limit in which the variation of the clutch control torque is reduced;
• and
• a control torque calculating step of calculating the clutch control torque to control a clutch by adding, by the controller, the final torque variation to the just previous clutch control torque.
