  • the assistance motor 26 of the traction device 39 exerts a great effort to compress the seal 38.
  • the position sensor 20 of the double lock lock 1 is not activated. It is desirable for the sensor 20 to be able to dissociate if the lock bolt 7 is in the first locking position ( figure 3 ) or in the second locking position ( figure 4 ) so as not to control the actuation of the traction device 39 too early.
  • the central unit 3 can send a signal on the control panel 41.

It is then possible for it to control the opening of the lock 1 and to restart the manual prepositioning so that the second safety catch is firmly engaged.
  • the fact of detecting the current consumed by the drive motor 26 and more generally the fact of detecting the energy consumed by the traction device 39 makes it possible to obtain additional information with respect to that of the position sensor 20. This makes it possible to use, for example, a cheap microswitch such as that illustrated in FIG. figure 1 .
  • the position sensor 20, responsive only to the position of the lever 6, may not disassociate if the lever 6 is cooperating with the first notch 13 or the second notch 14.
  • the information on the energy consumed by the traction device 39 compared to a threshold, will dissociate if the prepositioning of the opening was made only at the first safety catch 13 or if the second safety catch 14 has been correctly engaged.
  • having information on the energy consumed by the drive motor 26 may allow control redundancy in the case of a position sensor 20 capable of detecting whether the second detent 14 of the bolt lock 7 has been correctly engaged. This redundancy can detect a potential failure of the closure system.
  • the notch 15 allows a pencil to push the abutment surface 12 so that the lock bolt 7 arrives in the first locking position illustrated in FIG. figure 3 .
  • This situation can occur while the opening 37 is wide open.
  • the front portion 10a of the strike device abuts, not on the second branch 11 of the U-shape of the lock bolt 7, but abuts on the first branch 9. This has as effect of bringing the lock bolt 7 into the second locking position while the front portion 10a is not trapped between the two U-shaped arms 9 and 11 of the lock bolt 7.
  • the traction device 39 is actuated while the opening 37 is not hooked by the double-notch lock 1.
  • the energy consumed by the drive motor 26 of the striker device 2 is almost zero, because the strike device is actuated in a vacuum.
  • the comparison of the energy consumed by the final traction device 39 with a minimum threshold makes it possible to detect that the final traction was effected in a vacuum. A signal can be sent to the dashboard 41.
  • control unit 3 can control the latch device 2 so that the ring 10 returns to the extended position 29.
  • the cocking cam 5 of the double-lock lock 1 can be actuated in such a way that the lock bolt 7 is returned to its open position ( figures 1 and 2 ).
  • control method can also take into account the external temperature which has a significant influence on the stiffness of the seal 38.
  • the relevant current threshold consumed by the drive motor 26 is higher. for an outside temperature of -40 ° C than for + 25 ° C. It is also possible to adjust the operating time of the drive motor 26 of the latch device 2, which can for example be 250 milliseconds in summer and 350 milliseconds in winter. It will thus be possible to obtain additional redundant information with respect to the position sensors 32 or 33 of the latch device 2.
