Patent abstract

A position monitoring means for detecting the locked position of a locking element is assigned to at least one locking element. Furthermore, each position monitoring means is operatively connected to a control means for checking on whether a proper locked state prevails such that the actual state and the setpoint state of the locking element are comparable so that if these states do not correspond, an acknowledgment signal can be generated. In this way, it is possible to check on whether all the doors and hatches of a vehicle are properly locked after a locking operation has been performed.
