Parking lock module for actuating a parking lock in a motor vehicle

A parking lock module for actuating a parking lock in a motor vehicle, having a housing, wherein a positioning member for the actuation of the parking lock is accommodated in longitudinally displaceable fashion, said positioning member is movable from a locking position into an unlocking position and vice versa and is selectively fixable relative to the housing with an arresting device, said arresting device has a detent contour fixed to the positioning member and has a detent element on the housing, which detent element is movable from an arresting position, wherein said detent element is in engagement with the detent contour, into a release position, wherein said detent element releases the detent contour, and vice versa, wherein the detent element is preloaded into the arresting position with a spring and is movable, counter to the preload of the spring, into the release position with at least one fluidic actuator with a pressurizable effective surface, wherein the detent element is formed as a piston which is guided displaceably along a feed axis and which forms the pressurizable effective surface of the fluidic actuator,

• wherein the detent element is movable, counter to the preload of the spring, into the release position also by means of an electromagnetic actuator with an armature which is displaceable along the feed axis;
• and
• wherein said fluidic actuator is, in relation to the positioning member, situated on the feed axis in front of the electromagnetic actuator.
