Method for controlling clutch of vehicle with automated manual transmission

A method of controlling a clutch of an automated manual transmission (AMT) vehicle, the method comprising:

• when a shift to current stage completes during an operation of the AMT vehicle, performing, with a controller, a micro-slip control of a clutch to learn clutch transmission torque characteristics, wherein the micro-slip control is a slip control performed in a state where an amount of slip of the clutch is maintained to a predetermined level;
• when a slip releasing condition is satisfied based on the clutch transmission torque characteristics, performing, with the controller, a full-lock control of the clutch;
• and
• when it is determined that a shift from the current stage to a target stage is required based on driving conditions including driving state of the AMT vehicle, performing, with the controller, the micro-slip control of the clutch until a shift to the target stage starts,
• wherein performing the full-lock control of the clutch further comprises:
• determining that the slip releasing condition is satisfied when an absolute value of a difference between an engine torque and a clutch torque is maintained below a first reference value for a first predetermined amount of time, and when an absolute value of the amount of slip of the clutch is maintained below a second reference value for a second predetermined amount of time.
