Abstract

A method of searching for a sync start in an automated manual transmission includes manual transmission mechanism operated using an actuator. This method can accurately search for a sync start that acts as an important reference for the control in a shift operation so that the sync start can be used for the control of the actuator, which improves shifting response and reduces the chance of a shifting impact occurring, thereby obtaining a high quality of shifting in a reliable fashion.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0143676 filed on December 11, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention generally relates to a method of searching for an origin of synchronization in an automatic manual transmission, and more particularly, to a technique for searching for an origin of synchronization when using a related art such as a dual clutch transmission (DCT) or an automatic manual transmission (AMT). ) The point at which actual synchronization begins when the actuators in the AMT device perform a shift operation. Background technique [0004] In a transmission device using a manual transmission of the related art, when a shift operation is started after a selection operation, a sleeve in a neutral position slides linearly in a direction in which a target gear is placed. Simu...
