Design of the Lock and Drive

|---|---|
| 1 | Rotary striker |
| 2 | Rotary striker pull pawl |
| 3 | Advance detent tooth for rotary striker |
| 4 | Drive pawl |
| 5 | Automatic Soft Close function drive actuating lever |
| 6 | Locking pawl |
| 7 | Rotary striker main detent tooth |
| 8 | Hall sensor installation locations |
Light closing causes the advance detent tooth (3) of the rotary striker (1) to engage on the locking pawl (6). The Automatic Soft Close function drive pulls on the actuating lever (5). The actuating lever rotates the rotary striker by means of the pull latch (4) until it is rotated over the main detent tooth (7). The locking pawl can now engage in the main detent tooth of the rotary striker. The rotary striker is thus secured and the lock can no longer open by itself.

| 1 | Bowden cable |
| 2 | Control electronics |
| 3 | Bowden cable drive wheel |
| 4 | Drive worm |
| 5 | Idler gear |
| 6 | Drive motor |
The Automatic Soft Close function drive motor (6) has a two-start worm (4) on its shaft. This permits drive in the CLOSE direction for the Automatic Soft Close function. The rotary motion of the drive worm is transferred to the driven wheel (3) by the idler gear (5). The drive gear transfers the rotary motion to the Bowden cable (1). This means that the actuating lever in the lock is pulled by the Bowden cable and thus the vehicle door is fully closed.
