Description
Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patentanspruches 1The invention relates to a method according to the preamble of Claim 1
Obwohl grundsätzlich die Beseitigung aller schienengleichen Bahnübergänge angestrebt wird, werden, insbesondere an Strecken mit schwachem oder mittlerem Verkehrsaufkommen, noch lange Zeit derartige Bahnübergänge in Betrieb sein.Although fundamentally the elimination of all appearances Level crossings are aimed for, especially on routes with low or medium traffic, for a long time such level crossings be in operation.
Schienengleiche Bahnübergänge im Bahnhofsbereich werden heute in der Regel von einem Stellwerk aus bedient, wobei Schranken und Lichtsignale über Drahtverbindungen angesteuert und gesichert werden. Erst nach signaltechnisch sicher übertragener Rückmeldung des Schrankenverschlusses und der Anschaltung der vorhandenen Lichtsignale können Hauptsignale, die Zugfahrten über den Bahnübergang freigeben, auf Fahrt gestellt werden. Railroad level crossings in the station area are today in usually operated from a signal box, with barriers and Light signals controlled and secured via wire connections become. Only after feedback that has been transmitted safely the barrier lock and the connection of the existing ones Light signals can be main signals that train journeys over the Release the level crossing, be put on the move.
Bahnübergänge auf der freien Strecke werden häufig als Lokführer-überwachte Bahnübergänge ausgeführt, wobei ein Schaltkontakt in einem Abstand, der abhängig von der Streckenhöchstgeschwindigkeit, den schlechtesten Zugbremseigenschaften und der Schrankenschließzeit ist, das Schrankenschließen auslöst. Ein Lokführersignal im Bremswegabstand vor dem Signal gibt dem Triebfahrzeugführer dann die Erlaubnis zum Passieren, wenn der Bahnübergang verschlossen ist. Die Schaltkontakte und Signale sind mit der Logikeinheit des Bahnüberganges über Kabel verbunden.Level crossings on the free route are often called Train driver-monitored level crossings executed, one Switch contact at a distance that depends on the Line speed, the worst Train braking properties and the barrier closing time is that Closing barriers triggers. A train driver signal at the braking distance before the signal, the driver then receives permission to Pass when the level crossing is closed. The Switch contacts and signals are with the logic unit of the Level crossing connected by cable.
Zusätzliche Sicherungsmaßnahmen für Bahnübergänge an Schnellfahrstrecken sind z.B. in einem Aufsatz von W.Köth und 0. Wolf mit dem Titel "Der Beitrag der Signaltechnik zum Schnellverkehr" in "Eisenbahntechnische Rundschau", 1968, Heft 12, Seite 533, insbesondere in Kapitel IV, auf Seite 538 beschrieben.Additional security measures for level crossings High-speed routes are e.g. in an essay by W.Köth and 0. Wolf entitled "The contribution of signal technology to the Schnellverkehr "in" Eisenbahntechnische Rundschau ", 1968, issue 12, Page 533, especially in Chapter IV, on page 538.
Sowohl die von Stellwerken aus gesteuerten Bahnübergänge als auch die Lokführer-überwachten Bahnübergänge auf der freien Strecke sind aufwendig in ihrer Unterhaltung. Die Kabelverbindungen entlang der Strecke und die erforderlichen, das Freifahren des Bahnüberganges meldenden Gleisschaltmittel sind außerdem störungsanfällig. Both the level crossings controlled from signal boxes and the train driver-monitored level crossings are on the free route elaborate in their entertainment. The cable connections along the Route and the necessary, clearing the level crossing Reporting track switching devices are also prone to failure.
Systeme zur automatischen Steuerung und Sicherung von Schienenfahrzeugen, die ständig oder zeitweise mit streckenseitigen Einrichtungen Daten austauschen und ihre Geschwindigkeit nach Bremskurven einstellen, die anhand von in einer streckenseitigen Einrichtungen vorgegebenen Streckenliste enthaltenen Haltepunkten und Streckenhöchstgeschwindigkeiten einerseits und Fahrzeugeigenschaften andererseits berechnet werden, werden als dem Fachmann bekannt unterstellt. Hiervon geht die Erfindung aus.Systems for the automatic control and securing of rail vehicles, the exchange data continuously or temporarily with trackside facilities and adjust their speed according to braking curves, which are based on in one Track-side facilities included predetermined route list Stops and line speeds on the one hand and Vehicle properties, on the other hand, are calculated as being known to those skilled in the art known assumes. The invention is based on this.
EP 0 433 768 offenbart ein Verfahren, bei welchem eine Balise zur Ankündigung eines Bahnübergangs in einem bestimmten Abstand vor diesem Bahnübergang vorgesehen wird. Wenn ein sich dem Bahnübergang näherndes (Eisenbahn-) Fahrzeug diese Balise überfährt, wird eine (kurzzeitige) Kommunikationsverbindung zwischen dieser Balise und einem Empfänger im Fahrzeug aufgebaut und dem Fahrzeug darüber eine Identifikationsnummer und der aktuelle Abstand von dieser Balise zum Bahnübergang mitgeteilt. Das Fahrzeug meldet seine aktuelle Geschwindigkeit und die aktuelle Distanz zu einer Bahnübergangslogik des Bahnübergangs zurück . Unter der Annahme einer maximalen Beschleunigung auf eine maximale erlaubten Höchstgeschwindigkeit berechnet die Bahnübergangslogik eine maximale Zeit bis zum Sichern oder Schließen des Bahnübergangs, d.h. den notwendigen Schließzeitpunkt und sendet ein Acknowledgement-Signal an das Fahrzeug zurück. Da der tatsächliche notwendige Schließzeitpunkt dabei bedeutend später als der errechnete notwendige Schließzeitpunkt sein kann, können wiederholte Meldungen des Fahrzeugs über den jeweils aktuellen Ort und der jeweils aktuellen Geschwindigkeit angefordert werden, um der Bahnüberganglogik eine iterativen Berechnung optimalerer, d.h. spätere Schließzeitpunkte zu ermöglichen. Der Nachteil besteht dabei, dass keine Einbindung des Bahnübergangs als Streckenelement in ein oben genanntes automatisches Steuerung und Sicherungssystem erfolgt. Dadurch können Synergieeffekte einerseits nicht genutzt werden und andererseits aufgrund fehlender Kenntnis von einer im Fahrzeug vorliegenden individuell berechneten Bremskurve kein optimales Ergebnis, d.h. minimale Schließzeiten des Bahnübergangs erreicht werden.EP 0 433 768 discloses a method in which a balise for announcement a level crossing at a certain distance before this level crossing is provided. If a (railway) approaching the level crossing If the vehicle runs over this balise, it becomes a (brief) communication link between this balise and a receiver in the vehicle and the Vehicle with an identification number and the current distance from it Balise communicated to the level crossing. The vehicle reports its current Speed and the current distance to a level crossing logic of the Level crossing back. Assuming a maximum acceleration the level crossing logic calculates a maximum permitted maximum speed a maximum time until the level crossing is secured or closed, i.e. the necessary closing time and sends an acknowledgment signal to the Vehicle back. Because the actual necessary closing time is significant can be later than the calculated necessary closing time repeated reports of the vehicle about the current location and the each current speed can be requested to the level crossing logic an iterative calculation more optimal, i.e. later closing times too enable. The disadvantage is that the Level crossing as a route element in an above-mentioned automatic Control and security system is carried out. This can create synergy effects on the one hand not be used and, on the other hand, due to a lack of knowledge of an im The vehicle's individually calculated braking curve is not optimal Result, i.e. minimum closing times of the level crossing can be achieved.
Der Erfindung liegt die Aufgabe zugrunde, die Steuerung von Bahnübergängen in oben genannte Systeme zur automatischen Steuerung und Sicherung von Schienenfahrzeugen zu integrieren. Dabei soll die Integration dergestalt erfolgen, daß möglichst kurze, an die aktuelle Fahrzeugdynamik angepasste Bahnübergangssperrzeiten ermöglicht werden.The invention has for its object the control of level crossings in Above mentioned systems for automatic control and security of Integrate rail vehicles. The integration should take place in such a way that as short as possible, adapted to the current vehicle dynamics Level crossing closure times are made possible.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. This object is achieved by the features of patent claim 1.
Dabei ist die Verwendung von Funk zur Fernsteuerung von
Bahnübergangseinrichtungen vom Fahrzeug aus für sich bekannt (siehe
z.B. DE 43 31 431 C1, Fig. 2 und Beschreibung Spalte 4, letzter
Absatz bis Spalte 5, Zeile 21). Dort bestimmen jedoch ortsfeste
Streckeneinrichtungen den Zeitpunkt der Ausgabe einer
Sicherungsanforderung für den vorausliegenden Bahnübergang. Eine
Berücksichtigung der individuellen Fahrzeuggeschwindigkeit bei der
Bahnübergangssicherung ist damit dort nicht möglich, es muß
vielmehr immer von der maximal möglichen Geschwindigkeit des
schnellsten Fahrzeuges ausgegangen werden, was bei langsam sich
nähernden Fahrzeugen unnötig lange Bahnübergangssperrzeiten
bedingt. Bei dem Verfahren nach der Erfindung wird die
Schließanforderung dagegen abhängig von einer aus den
Bremseigenschaften des Fahrzeuges und dem Streckenort des
Bahnüberganges berechneten Bremskurve im
Weg- Geschwindigkeits-Diagramm (Fahrprofil) ausgelöst, erfolgt
somit, abhängig von der aktuellen Fahrzeuggeschwindigkeit, an einem
Streckenpunkt, von dem aus, sollte der Bahnübergang auf die
Schließaufforderung nicht reagieren, das Fahrzeug gerade noch durch
eine Betriebsbremsung vor dem Bahnübergang zum Stillstand gebracht
werden kann.The use of radio for remote control of level crossing devices from the vehicle is known per se (see, for example, DE 43 31 431 C1, FIG. 2 and description in column 4, last paragraph to column 5, line 21). There, however, fixed route facilities determine the point in time at which a security request is issued for the level crossing ahead. A consideration of the individual vehicle speed in the level crossing protection is therefore not possible there, rather the maximum possible speed of the fastest vehicle must always be assumed, which causes unnecessarily long level crossing blocking times for slowly approaching vehicles. In the method according to the invention, on the other hand, the closing request is dependent on a braking curve calculated from the braking properties of the vehicle and the route location of the level crossing
Depending on the current vehicle speed, the path-speed diagram (driving profile) is triggered at a point on the route from which, if the level crossing does not respond to the closing request, the vehicle is brought to a standstill by a service brake before the level crossing can.
Ausgestaltungen des Verfahrens nach der Erfindung sind in den Unteransprüchen beschrieben.Embodiments of the method according to the invention are in the Subclaims described.
So stellt die in Patentanspruch 2 angegebene Bemessung sicher, daß noch keine Bremsung des Fahrzeuges erfolgt, wenn der Bahnübergang auf die Schließanforderung vorschriftsmäßig reagiert.So the dimensioning specified in claim 2 ensures that the vehicle has not yet braked when the level crossing responded to the closing request in accordance with regulations.
Anspruch 3 betrifft weitere Versuche, einen zunächst nicht reagierenden Bahnübergang nach bereits eingeleiteter Bremsung noch zu schließen, und den Abbruch der Bremsung, wenn derartige Versuche erfolgreich sind. Claim 3 relates to further attempts, initially not responsive level crossing after braking has already been initiated close, and abort braking if such attempts are successful.
Eine in Anspruch 4 wiedergegebene Ausgestaltung betrifft die Verarbeitung von Schließanforderungen im Hinblick auf Bahnübergänge an mehrgleisigen Strecken, die gleichzeitig Schließanforderungen von mehreren Fahrzeugen bekommen können.An embodiment reproduced in claim 4 relates to Processing of closing requests with regard to level crossings on multi-track lines that have locking requirements at the same time can get from multiple vehicles.
Gegenstand der Ansprüche 5 und 6 ist die Wiederöffnung eines Bahnüberganges nach Durchfahrt eines Fahrzeuges.The subject of claims 5 and 6 is the reopening of a Level crossing after passage of a vehicle.
Anspruch 7 und Anspruch 8 betreffen Maßnahmen zur Weiterführung des Fahrbetriebes im Störungsfall.Claim 7 and claim 8 relate to measures to continue the Driving in the event of a fault.

In Fig. 1 ist schematisch eine zweigleisige Eisenbahnstrecke STR
wiedergegeben mit einem schienengleichen Bahnübergang BÜ, der mit
Schranken SCH und Lichtsignalen LS ausgestattet ist und über Funk
von auf der Strecke verkehrenden Zügen Z1, Z2 aus geschlossen und
geöffnet werden kann. Die Funkverbindung besteht dabei entweder
direkt oder über ein Stellwerk STW als Relaisstelle zu einer
Bahnübergangslogik BÜL, einer intelligenten Steuereinrichtung in
der Nähe des Bahnüberganges, die mit einer
Sende- Empfangseinrichtung für Datenfunk ausgestattet ist und die
lokalen Aktoren und Sensoren des Bahnüberganges ansteuert und
überwacht. Über die Sende- Empfangseinrichtung empfängt die
Bahnübergangslogik Schließanforderungen und
Wiederöffnungs-Erlaubnisse von den Fahrzeugen oder dem Stellwerk
STW und gibt nach Schließen des Bahnüberganges Vollzugsmeldungen an
die jeweiligen Fahrzeuge bzw. das Stellwerk aus. In Fig. 1, a two-track railway route STR is shown schematically with a level crossing level crossing BÜ, which is equipped with barriers SCH and light signals LS and can be closed and opened by radio from trains Z1, Z2 running on the route. The radio connection exists either directly or via a signal box STW as a relay point to a level crossing logic BÜL, an intelligent control device near the level crossing, which is connected to a
Transceiver is equipped for data radio and controls and monitors the local actuators and sensors of the level crossing. The level crossing logic receives closing requests and via the transceiver
Reopening permits from the vehicles or the signal box STW and, after the level crossing has closed, issues execution reports to the respective vehicles or the signal box.
Die zur Berechnung ihrer Fahrkurven notwendigen Streckeninformationen - zu denen z.B. auch der Ort eines Bahnüberganges gehört - bekommen die Fahrzeuge über kontinuierlich wirkende Übertragungseinrichtungen z.B. Linienleiter LL oder Funk oder über punktförmig wirkende Übertragungseinrichtungen PD vom Stellwerk mitgeteilt.The ones necessary to calculate your driving curves Route information - to which e.g. also the place of one Level crossing heard - the vehicles get over continuously acting transmission devices e.g. Line manager LL or radio or via point-acting transmission devices PD from Interlocking communicated.
Fig. 2 zeigt im Weg (s)-Geschwindigkeits (v)-Diagramm zwei
Fahrkurven mit den Anfangsgeschwindigkeiten V1 und V2, die zwei
Zügen Z1 und Z2 zugeordnet sein mögen. Im
Weg-Geschwindigkeits-Diagramm sind für alle Haltepunkte und
Langsamfahrstellen Bremskurven BR1, BR2 enthalten, die jedes
Fahrzeug nach dem Ort des Haltepunktes und den eigenen
Bremseigenschaften berechnet. Die in der Figur 2 enthaltenen Züge
Z1, Z2 mögen hier gleiche Bremseigenschaften haben, so daß für sie
dieselben Bremskurven vor den Haltepunkten Bahnübergang BÜ und
Bahnhof BF gelten mögen.2 shows in the path (s) -speed (v) diagram two driving curves with the initial speeds V1 and V2, which may be assigned to two trains Z1 and Z2. in the
Path-speed diagrams contain braking curves BR1, BR2 for all stopping points and slow speed points, which each vehicle calculates based on the location of the stopping point and its own braking characteristics. The trains Z1, Z2 contained in FIG. 2 may have the same braking properties here, so that the same braking curves may apply to them at the level crossing level crossing and train station BF stopping points.
Zug Z1 fährt mit hoher Geschwindigkeit V1 auf den Bahnübergang BÜ zu. Aus der Streckeninformation, die der Zug über Linienleiter, über Funk oder über eine punktförmige Übertragungseinrichtung aufgenommen hat, kennt das Fahrzeuggerät des Zuges die Zeitspanne, die der Bahnübergang vom Empfang einer Schließanforderung an bis zur Abgabe einer Meldung über den erfolgten Verschluß benötigt. Je nach seiner gefahrenen Geschwindigkeit berechnet der Zug die innerhalb dieser Zeit zurückgelegte Strecke und gibt zu einer Zeit t1, zu der er sich noch etwas weiter als diese Strecke vor dem Ort befindet, an dem er die Bremskurve BR1 erreicht, über Datenfunk eine Schließanforderung an den Bahnübergang ab. Reagiert der Bahnübergang vorschriftsmäßig, so gibt er, nachdem der Verschluß erfolgt ist, d. h., je nach Art des Bahnüberganges, die Lichtsignale Rot zeigen und/oder die Schranken geschlossen und verriegelt sind, zu einer Zeit t2 eine Vollzugsmeldung an den Zug zurück. Das Fahrzeuggerät hebt daraufhin den dem Bahnübergang zugeordneten Haltepunkt in seiner Streckenliste auf. Train Z1 drives at high speed V1 onto the level crossing BÜ to. From the route information that the train uses to route lines, by radio or via a punctiform transmission device the vehicle's device on the train knows the time span, the level crossing from the receipt of a closing request to needed to submit a message about the closure. ever the train calculates the speed based on its speed distance traveled within that time and returns at a time t1, to which he goes a little further than this route on site is located at which it reaches the braking curve BR1, via radio data transmission a closing request to the level crossing. Does the Level crossing according to regulations, he gives after the closure has occurred, d. that is, depending on the type of level crossing, the Light signals show red and / or the barriers closed and are locked, a completion report to the train at a time t2 back. The vehicle device then lifts the level crossing assigned stop in its route list.
Damit verschwindet die Bremskurve BR1 und der Zug fährt mit gleichbleibender Geschwindigkeit V1 bis zur nächsten Bremskurve BR2, die z.B. dem Bahnhof BF zugeordnet ist, weiter. Reagiert der Bahnübergang nicht wie vorgeschrieben, wird zum Zeitpunkt t2 keine Vollzugsmeldung empfangen. Der Zug erreicht die Bremskurve BR1 und leitet eine Betriebsbremsung ein. Dabei bremst der Zug entlang der Bremskurve BR1 bis auf eine niedrige Durchfahrtgeschwindigkeit Vd ab, mit der er dann den Bahnübergang unter Fahrt auf Sicht passiert. Während des Bremsvorganges kann jedoch die Schließanforderung wiederholt werden. Reagiert der Bahnübergang dann doch noch auf die Schließanforderung, so kann nach Empfang der Vollzugsmeldung der Bremsvorgang abgebrochen und der Zug wieder beschleunigt werden.The braking curve BR1 disappears and the train goes with it constant speed V1 until the next braking curve BR2, e.g. is assigned to the station BF. Does the Level crossing does not go as required, there will be none at time t2 Execution notification received. The train reaches the braking curve BR1 and initiates service braking. The train brakes along the Braking curve BR1 down to a low passage speed Vd with which he then crosses the level crossing while driving on sight happens. However, during the braking process Closing request can be repeated. The level crossing reacts then on the closing request, after receiving the Execution message the braking process canceled and the train again be accelerated.
Der mit niedrigerer Geschwindigkeit V2 fahrende Zug Z2 sendet seine Schließanforderung zum Zeitpunkt t3, an den Bahnübergang BÜ ab. Er ist zu dieser Zeit aber bereits viel dichter an den Bahnübergang herangefahren. Aufgrund der niedrigen Geschwindigkeit kann er dennoch sicher entlang der Bremskurve BR1 auf die Durchfahrtgeschwindigkeit Vd abgebremst werden, wenn vom Bahnübergang nicht zum Zeitpunkt t4 die Meldung über den Vollzug des Verschlusses eingeht. Geht eine solche Meldung rechtzeitig ein wird, wie im Falle des Zuges Z1, der dem Bahnübergang BÜ zugeordnete Haltepunkt aufgehoben und der Zug Z2 fährt mit der Geschwindigkeit V2 weiter. Nach Passieren des Bahnüberganges geben alle Züge eine Wiederöffnungs-Erlaubnis an den betreffenden Bahnübergang ab. Dies geschieht zu einem Zeitpunkt t5 an einer Stelle, an der der Zugschluß den Bahnübergang verlassen hat. Ein am Ort des Bahnüberganges geschaffener Gleisabschnitt, der z.B. durch einen Gleisstromkreis oder mittels Achszählpunkten realisiert ist, kann zur Prüfung des Freiseins des Bahnüberganges zusätzlich herangezogen werden, das heißt, die Wiederöffnungs-Erlaubnis wird von der Bahnübergangslogik erst umgesetzt, wenn der den Bahnübergang enthaltende Gleisabschnitt freigemeldet ist. The train Z2 traveling at a lower speed V2 sends its Closing request at time t3 from the level crossing from. He is already much closer to the level crossing at this time moved up. Because of the low speed it can nevertheless safely along the braking curve BR1 on the Passage speed Vd are braked when from Level crossing does not report the execution at time t4 of the closure. Receives such a notification in good time will, as in the case of train Z1, the level crossing BÜ assigned stop and the train Z2 runs with the Speed V2 continues. Give after passing the level crossing all trains have a reopening permit to the concerned Level crossing from. This happens at a point in time t5 Point at which the end of the train left the level crossing. A on Track section created at the level crossing, e.g. by a track circuit or by means of axle counting points, can also be used to check that the level crossing is clear be used, that is, the reopening permit only implemented by the level crossing logic when the Level crossing containing track section is released.
Wird z. B. im Störungsfalle keine Wiederöffnungs-Erlaubnis empfangen, so kann nach Ablauf einer Wartezeit eine Wiederöffnung vorgenommen werden, wenn der am Ort des Bahnüberganges geschaffene Gleisabschnitt während der Zeit, in der der Bahnübergang geschlosen war, besetzt und wieder freigefahren wurde.Is z. B. in the event of a fault, no re-opening permit received, it can be reopened after a waiting period be made if the one created at the level crossing location Section of track during the time when the level crossing is closed was occupied and cleared again.
Bei Bahnübergängen an mehrgleisigen Strecken ist vor Wiederöffnung außerdem zu prüfen, ob nicht von einem sich auf einem anderen Gleis nähernden Zug eine Schließanforderung vorliegt. In diesem Falle bleibt der Bahnübergang geschlossen bis auch von diesem Zug eine Wiederöffnungs-Erlaubnis empfangen wurde und/oder ein in dem anderen Gleis gebildeter Gleisabschnitt besetzt und wieder freigefahren wurde.At level crossings on multi-track lines is before reopening also to check whether not from one to another track approaching train there is a closing request. In this case the level crossing remains closed until one of these trains Reopening permission has been received and / or one in which other track section formed occupied and again was freed.

- Method for integrating level crossings into automatic control and protection of rail vehicles, which exchange data constantly or at times with line-side devices and adjust their speeds according to braking curves, which are calculated in the vehicle on the one hand with reference to stopping points and maximum line speeds contained in a line list, which is conveyed by a line-side device to the rail vehicles, and with reference to vehicle attributes on the other hand, a radio data transmission connection existing between the vehicles (Z1, Z2) and a level crossing logic (BÜL) respectively that controls a level crossing device (SCH, LS) and is equipped with a radio transmitting and receiving device, characterized in thatthe level crossings (BÜ), identified individually by a characteristic, are included in the line list as cancellable stopping points,a vehicle (Z1, Z2) transmits a closure request to a level crossing lying ahead in the direction of travel at a time (t1, t3), this time (t1, t3) being determined, depending on the location of the level crossing, a preset time span from the receipt of a closure request to the delivery of a message on the completed closure and the braking curve (BR1) to this level crossing calculated in the vehicle, in the path and speed diagram in the vehicle such that the train can still be brought to a halt ahead of the level crossing (BÜ) by service braking in the event that no message is forthcoming andthe stopping point assigned to the level crossing in the line list is cancelled if the closure of the level crossing has been completed and a message regarding this has been received by the vehicle together with the characteristic of the respective level crossing.
- Method according to claim 1, characterized in that the distance to the braking curve (BR1) at which when reached a closure request is transmitted by the vehicle is specified depending on the vehicle speed such that the time required by the vehicle to travel this distance is equal to at least the sum of the barrier closing time and the data transmission times required to transmit the closure request and the completion message.
- Method according to claim 1 or claim 2, characterized in that, in the event that a closure request of a vehicle is not answered by the level crossing ahead by a completion message, once service braking has been initiated further closure requests are transmitted to the level crossing and the stopping point assigned to the level crossing is cancelled and thus service braking is interrupted as soon as a message indicating closure of the level crossing has been received by the vehicle.
- Method according to claim 1 to 3, characterized in that a closure request transmitted by a vehicle is stored by the level crossing logic of the level crossing addressed, together with a characteristic of the requesting vehicle, and a closure executed on account of the closure request is at least maintained, until permission to reopen arrives from the vehicle that requested the closure.
- Method according to one of claims 1 to 4, characterized in that closure of the level crossing is reversed if, following passage of the vehicle end of the vehicle that requested the closure at the location of the level crossing, permission to reopen containing the vehicle characteristic and the level crossing characteristic is issued by this vehicle and received by the level crossing logic and no closure request of another vehicle is present.
- Method according to claim 5, characterized in that reopening of the level crossing is also made dependent on whether a track section created in the area of the level crossing is emptied of vehicles.
- Method according to claim 5, characterized in that in the event of permission to reopen failing to materialize, reopening of the level crossing takes place if a track section created in the area of the level crossing is emptied of vehicles after an interim occupation and no closure request of another vehicle is present.
- Method according to one of the above claims, characterized in that if a message fails to materialize regarding completion of the closure of a level crossing, the closure of which level crossing was requested, braking of the vehicle below a low passage speed predetermined for the abnormal occurrence is interrupted by the vehicle driver and the level crossing may be passed running under caution.
