That is, in this advantageous embodiment, although the decoupling enable signal is formed using the standstill signal, additional becomes evaluated at least one other signal of the train or a vehicle to provide increased security, which, inter alia, stricter legal requirements or criteria catalogs of appropriate regulatory authorities sufficient. As a result, an increased evaluation precision compared to known systems is required, in which only the standstill signal is used to decide whether a possibly occurring uncoupling is to be considered permissible or inadmissible.

  • An initialization branch is given by the functional blocks 422, 424, wherein the functional block 422, which checks whether the carriage 230 is not coupled, is in turn connected to a vehicle voltage or a vehicle voltage terminal 421. If the carriage 230 is not coupled, ie its coupling device 243 is not connected to a corresponding coupling device of another following carriage (not shown), it is checked in the function block 424 whether the driver's console has been activated for a defined time interval. If this is not the case, then a branch is made into block 426, in which it is concluded that the carriage 230 is not coupled, and thus represents a terminal carriage 230.
  • the branch formed by the function blocks 428, 430, 432 successively checks whether the standstill signal STS (FIG. Figure 2a, 2b ) is active (block 428), whether the driver's console is activated for a defined time interval (block 430), and whether the carriage 230 is mechanically coupled (block 432). Only when these criteria are met is it also branched to block 426.
  • Figure 4c shows a logic diagram illustrating the signal flow, as it is used in another embodiment to set the flag "no pull-break".
  • this flag is preferably always set after an initialization of the control device 100 when all limit switches of the sensor means 121, 122, 123 have been checked and no decoupled state has been detected.
  • the flag is preferably stored over the entire operating period of the controller 100.
  • the terminal 441 is in turn connected to a vehicle voltage terminal of the train 200.
  • the flag "no pull-off" is set.
  • a safety loop is closed in blocks 448 or no quick brake is set, so that no safety braking is triggered.
  • the traction signals are driven in a predefined manner.
  • the block 450 is in turn with a Vehicle voltage terminal 441 'connected.
  • the function block 442 it is also possible to branch to the block 444 via the function block 446, with which it is checked whether there is no thread break at a coupling point, in which the flag "no thread break" is set.
  • the function block 442 is then passed through successfully if the logic block according to FIG Figure 4c checked carriage is about a Endwagen 230, while the function block 446 according to Figure 4c is then passed through successfully when the checked car is not the end car 230 and at the same time there is no draft break on the coupling device 241.
  • Illustrated diagrams are advantageously also implemented in the control device 100, in particular in the control unit 130. They can preferably be implemented as relay circuits or else in the form of a program for a microcontroller and / or a digital signal processor (DSP).
  • DSP digital signal processor
  • FPGA programmable logic devices
  • CPLD programmable logic devices
  • ASIC application specific integrated circuits
  • the clutch states "mechanically coupled” or “mechanically uncoupled” are automatically detected by means of the clutch state signals S1, S2, S3 and the sensor means 121, 122, 123 (for Example limit switch), and a flag "no pull-break" is set or initialized.
  • the flag can be realized, for example, in a hard-wired circuit by a relay. If a coupling state changes at the uncoupled coupling point 243 of the endcarriage 230, then, according to a preferred embodiment, this has no influence on the overtravel detection according to the invention.
  • the signaling of a wanted train separation is advantageously carried out as already described above using the dedicated decoupling enable signal EF, which in turn can depend on various criteria (STS, PHLL, MOD).
  • the following technical implementation results in detail: is a driver's seat in the train 200 / train activated, for example, in a power car 210, then over a short time interval, the state of each coupling device 241, 242, 243 in the train 200 queried and stored in the controller 100, for example, using the flag "no pull-break". Until a renewed activation of a driver's desk, the monitoring according to the invention remains active.
  • the state of a coupling device 241, 242 changes from “coupled” to "not coupled", irrespective of the cause of the release (for example activation of uncoupling valve / emergency lug etc.), the state of a coupling device 241, 242 changes as a result of an unintentional train separation / unintentional uncoupling Flag "no pull-break" deleted and one or more of the vehicle reactions described several times above triggered.
  • the vehicle reactions may be For example, the interruption of a safety / rapid braking loop in the still leading tensile part 210 and the severed tensile part 220, 230 act.
  • the other vehicle reactions, which are preferably also carried out, are described above.
  • the current requirements for the vehicle reaction of the train 200 can be met, in particular in the case of an unwanted train separation, as described in the Supplementary Regulations No. B015 "from ⁇ 4 AEG and EBO derived protection goals for the coupling of vehicles with automatic Clutch in Stand "(Internet: WWW.EBA.BUND.DE home page> Infotheque> Vehicles> Brakes).
  • the procedure for generating the decoupling enable signal EF is as follows: in order to signal a regular decoupling by means of the decoupling enable signal EF according to the invention, the main air line is lowered from a control pressure to a defined value of, for example, 2.8 bar , And with an additional presence of the standstill signal STS a decoupling operation (for example, with key switch or Entkupplungsseil) can be performed without this is detected as a pull-off, because the controller 100 has been successfully informed about the disengagement release signal EF according to the invention that desired decoupling process will be performed.
  • a further particularly preferred variant according to the triggering of a pull-break, that is, after the detection of an unwanted uncoupling, only by a deactivation and re-activation of a driver's desk (If necessary, connected with a renewed confirmation of the now changed train configuration) in the train 200 / train part, the circuit or controller 100 are reset.
  • the control device 100 is preferably equipped with the communication interface 140 for communication with the driver's desk of the railcar 210 or another vehicle, but may also have further or more interfaces to other systems.
  • the dark switching of the train closing signals can only be canceled by operating a special operating element by the driver / driver, but first the event "pull-off" must be acknowledged by the driver, for example by a corresponding driver Input at a man-machine interface of the control device 100 provided for this purpose, such as a key switch or a graphical user interface.
  • a man-machine interface of the control device 100 provided for this purpose, such as a key switch or a graphical user interface.
