Abstract

A method for recognition of the synchronization position and the end of the synchronization operation in an automated shiftable transmission with an electromotive shift actuator is disclosed, which is characterized in that the rotational speed of the shift actuator is detected and the synchronization position, as well as the end of the synchronized operation, is determine based upon the change of the rotational speed.
