Abstract
A drive device for a lid of a motor vehicle includes a first fastening element connectable to a stationary component or to a movable component, and a housing tube located at the end of the drive device opposite the first fastening element and is free to move axially relative thereto. The housing tube includes, at the end opposite the first fastening element, a second fastening element connectable to the movable component or to the stationary component. A spindle drive including a threaded spindle and a spindle nut mounted on the threaded spindle is actuatable by a rotary device to move the first fastening element and the housing tube axially relative to each other. A stroke position of the first fastening element can be detected by a magnetic field sensor which senses longitudinal movements of a permanent magnet of the spindle along a sensitivity area of the stationary magnetic field sensor.
