摘要

The lock device has an electronic control device (5) moving a rod-shaped locking unit (1) from an unlocking position (I) to a locking position (II) for activating a parking lock. The control device releases the locking unit, which is in the unlocking position, for moving to the locking position during energy supply. An auxiliary locking unit (9) is attached to the locking unit and moves automatically to a locked position (III) during energy supply. The auxiliary locking unit locks the locking unit, which is released from the control device, in its unlocking position. An independent claim is also included for a method for activating and deactivating a parking lock device.
