Abstract
An operating device for selecting shift stages in a shift-by-wire gearbox. The device comprises a selector lever which is movable between a drive gear position and a park position, and a locking device with a spring-loaded detent pin and a lock-in gate. An actuator device, that moves the selector lever, comprises a disengagement device. A detent pin and a lock-in gate can be brought, via a disengagement device, from a first relative position, in which the detent pin engages a shifting track of the lock-in gate, into another relative position, in which the detent pin disengages the shifting track. The operating device facilitates simple and safe actuator-induced return of the selector lever, into the park position, and offers the driver reliable optic and tactile feedback about the actual shift condition of the transmission.
