摘要

A motor vehicle transmission is shiftable in a track pattern with a selector track and shift tracks. A shifter element moves along the tracks when the transmission is shifted from one gear ratio to another. The shifts are directed by a control device sending command signals to an actuator device which, in turn, applies an actuating force to the transmission. A main position-detecting device detects the position of the shifter element relative to the selector track and shift tracks, and a redundant position-detecting device performs an additional, redundant determination of the shifter-element position.
