Method of searching for sync start in automated manual transmission

A method of searching for a sync start in an automated manual transmission, comprising:

• a slip preparing step of operating, in a parked position, a clutch which is restrained so as not to relatively rotate with a sleeve into a slip state, wherein an engine speed is higher than a rotation speed of the clutch;
• an actuator operating step of moving the sleeve toward a clutch gear from a neutral position;
• and
• a first position determination step of locating a point where the rotation speed of the clutch is decreased at the actuator operating step in the parked position and the slip state of the clutch and determining the point as the sync start.

• an actuator operating step of moving the sleeve toward a clutch gear from a neutral position;
• a third position determination step of determining whether or not a movement of the sleeve by the actuator operating step has stopped;
• and
• a first position determination step of determining a point where the rotation speed of the clutch has decreased and where a movement of the sleeve by the actuator operating step has stopped simultaneously in the parked position and the slip state of the clutch, as the sync start.
