Abstract

An actuating device for selecting shift positions of a shift-by-wire gear shifting transmission. The actuating device comprises a selector lever that may be moved between at least a drive position and a parking lock position, the lever having stable selector lever settings, and a locking device for locking the selector lever in the parking lock position. The locking device comprises an actuator device such that the selector lever may be moved from the drive position into the park position by way of the locking and actuator devices. The actuating device makes it possible that the position of the selector lever of the actuating device matches the actual shifting state of the transmission at all times, and thereby offers reliable optical and tactile feedback for the driver of the actual shifting state of the transmission and may also serve as a mechanical emergency actuator for the parking lock.
