A method of operating a vehicle dressing Kommunikati ^¬ onseinrichtungen, traction vehicle, the vehicle and control vehicle ribbon

The invention relates to a method for operating a vehicle association with a traction vehicle and at least one vehicle and for determining the affiliation of the vehicle to the vehicle body.

Such a method is known from German Patent DE 198 30 053 Cl. The known method relates to a vehicle body in the form of a train with a traction vehicle and vehicles in the form of wagons. In this case, both the traction vehicle and the wagons on communication equipment, the communication equipment of the waggons in the PoI- ling operation by means of electromagnetic waves send out data sets for the identification of the respective wagon. In the known method, a mobile Datenerfas ^¬ sungsgerät allows vehicle data with logistics information that are stored e- lektronisch in on-board computers of the communication equipment of the waggons, and thereby determine the affiliation of a wagon to the train.

However, a disadvantage of the known method is precisely that the determination of those vehicles belonging to the vehicle association is comparatively complicated and requires an additional work step. It should be taken into account in general that neither in a marshalling yard nor on a free route can it be assumed that only data records are received from such vehicles that actually belong to the vehicle association. Thus, appropriate records, especially at Use of a radio link between the locomotive and the vehicles, for example, be sent by located on a neighboring track vehicles.

The object of the present invention is of providing a particularly simple and efficient method of the type mentioned at the outset a ^¬.

This object is achieved for a method for operating a vehicle association with a traction vehicle and at least one vehicle and for determining the affiliation of the vehicle to the vehicle body according to the invention by determining the value of at least one kinematic measurement ^{variable of} the vehicle on the vehicle side. is agreed value of the measured variable with a powered vehicle side ^¬ be certain value of the measured variable is compared and the vehicle is recognized as belonging to the vehicle combination, provided that the comparison results in a match.

The inventive method has the advantage that with ^¬ means of a vehicle-specific value of a kinemati ^¬ rule measured value and a traction-unit-side specific value of the same measurand is possible by comparing the respective values a statement as to whether the person concerned de vehicle is part of the vehicle association, ie belongs to this vehicle association. The use of the movement of the vehicle Association's measured variables ^¬ SSE particular allows a distinction of, for example parked on adjacent tracks vehicles. Thus, it is advantageously avoided that appropriate Fahrzeu ^¬ ge that are not part of the vehicle association, Fälsch ^¬ SHORT- as this are considered to belong. In the context of the method according to the invention, the vehicle body may be any type of vehicle body. In addition to trains or train associations, this may be, for example, towing units of ships or jointly moving associations of road vehicles. It is also possible in principle that the vehicles of the driving association have their own drive or auxiliary drive.

It should be noted that the traction vehicle can be arranged in principle within the vehicle association at any position. In addition, of course, a corresponding vehicle association may include several traction vehicles. In this case, the measured variable can be determined either only for one of the traction vehicles or else for several or all of the traction vehicles and used for the comparison with the value determined on the vehicle side of the measured variable.

Usually, the vehicle ^{grouping will encompass} several vehicles or, respectively, several vehicles will be considered with regard to a possible affiliation with the vehicle association. In this case, the determination of the value of the at least one kinematic measured variable and the comparison with the drive-vehicle-determined value of the measured variable are preferably carried out for each of the vehicles. However, it should be ^noted that, even in the case where several vehicles belong to the vehicle group, it is not necessary for each of these vehicles to have a determination of the kinematic measured variable. Thus, it is conceivable, for example, that a corresponding determination is made only for selected vehicles of the vehicle association, such as the last vehicle starting from the traction vehicle. Unless be determined in the method of the invention, several kinematic measurements, the accuracy when determining the feed can be increased by a corresponding comparison with locomotive-side specific values of the measured variables affiliation of the vehicles to the vehicle association legally advantageous ^¬.

The method according to the invention preferably proceeds in such a way that a vehicle identifier of the vehicle belonging to the vehicle group is detected. This is advantageous because a preferably unique identi fication ^¬ of the respective vehicle is possible with ^¬ means of the vehicle identifier. In this case, a corresponding vehicle identifier can for example be permanently assigned to the respective vehicle or assigned to the vehicle before or at the end of the method.

In the context of the method according to the invention, in principle, any kinematic measured variable, such as the direction of travel, can be used and determined in any manner known per se. In a preferred embodiment of the inventive method, the place, the speed Accelerati ^¬ supply and / or the driving time period is used as kinemati ^¬ specific measured variable. This is before ^¬ geous, since the corresponding kinematic variables for determining the affiliation of a vehicle to the

Vehicle Association are particularly suitable. For detecting Bezie ^¬ hung as determination of the kinematic measure the vehicles as well as the traction unit in dependence on the per weiligen used ^¬ measured variable with the corresponding measuring equipment are provided directions. In a corresponding measuring device may be, for example, for measuring the speed of a Doppler radar, to determine the location and optionally the speed therefrom derived a receptions and seminars ^¬ ger a satellite-based navigation system, ie examples For example, a GPS receiver, or act as an acceleration sensor.

In principle can be carried out within the framework of the inventive method to compare the vehicle-specific value of the measurement ^¬ size with the traction vehicle side certain value of the measured ^¬ size by any component which can be part of the vehicle component ^¬ association or not. For example, the comparison can be made by a central control or planning office. In addition, communication within the vehicle association can basically be both wired and wireless. In addition to a cable connection, for example, an infrared interface can be used.

In a particularly preferred embodiment of the method according to the invention, the measured variable determined on the vehicle side is transmitted to the traction vehicle by means of a radio link. This means that the traction vehicle communicates with the vehicles of the vehicle association via a radio link or is connected. Advantageously, within the scope of this preferred development of the method according to the invention, it is thus possible to exchange information within the vehicle grouping without a wired connection, for example in the form of a wired cable bus or another continuous line, such as a compressed air line. Corresponding through-lines are ten in practice because of the required compounds from vehicle to vehicle as a result of Wackelkontak- and corrosion usually comparatively unzuverläs ^¬ sig. By transmitting the vehicle-specific measured quantity to the vehicle engine, it is further possible that the comparison of the vehicle-specific value of the measurement ^¬ size with the traction vehicle side particular value of the measurement large traction vehicle side done. This is advantageous because the locomotive has a central role within a vehicle Association customary ^¬ wise. Then this is the ^¬ particular the possibility of issuing of the vehicles of the vehicle Association received information directly to the leader of the traction unit. In the context of the preferred embodiment of the method according to the invention the Ermit ^¬ stuffs the membership of a vehicle running on the vehicle association moreover advantageously autonomously generating union inside the vehicle, so that, for example, Kommunikationsverbin ^¬ applications to central facilities, such as in the form of a control center of a railway system, advantageously for the functionality of the process of the method are not necessarily he ^¬ required. In this case, only a radio link with the traction vehicle is required by the vehicles of the vehicle association, so that advantageously the maximum length of the vehicle body is sufficient with regard to the range of the radio link. For example, a maximum permissible length of 750 m is specified for a vehicle association in the form of a freight train in Germany. Preference ^{¬ way} , the radio connection is done by means of an immedi ^¬ direct connection between the respective vehicle and the locomotive. Alternatively, however, it is also possible for example that individual or all vehicles of the vehicle association can serve as routing stations, ie as forwarding points between the relevant vehicle and the traction vehicle. Because the required range of the radio connection is comparatively low, the vehicles require comparatively little power or energy for the relevant communication connection. This is advantageous since it is desirable to ensure a maintenance ^¬ free energy supply of the vehicles, for example by suitable batteries, over a long period. In a preferred process of the invention proceeds in such a way that, in a vehicle combination containing more ^¬ reren vehicles based on the determined part of the vehicles values of the measured variable the last vehicle of the vehicle association and / or the ranking of the vehicles in the vehicle Association be ^¬ true is. Since an unwanted separation of Fahrzeugver ^¬ bands based on a loss of the last vehicle of the driving ^¬ convincing union can be reliably detected, comes from the ^¬ going last of the engine car of the vehicle association usually has a special significance. Zusätz ^¬ Lich or alternatively to the determination of the last vehicle of the vehicle dressing can advantageously be fully ^¬ permanent ranking of the vehicles in the vehicle Association ^¬ be true. This offers the advantage that accurate information about the structure of the vehicle body can be provided, for example, to a vehicle driver of the locomotive. This makes it possible, for example, to distinguish a technical defect of a communication device used for data transmission of a vehicle of the vehicle association from a separation of the vehicle association. If, for example, the communication device of a vehicle arranged in the middle of the vehicle body fails, then this may be due to the fact that vehicles, which are located farther away from the locomotive, are still accessible, can be distinguished from a separation of the vehicle body. It also allows a ranking determination of the vehicles of the vehicle in front Association ^¬ geous enough, even comparing them to used for operations management scheduling systems.

Advantageously, the method according to the invention is designed such that an acknowledgment message regarding the affiliation of the vehicle to the vehicle association is transmitted to the vehicle. This offers the advantage that the Vehicle is informed that it has been recognized as belonging to the Fahr ^¬ convincing association. Based on this information, the vehicle in question can thus adapt its further behavior accordingly.

In a further preferred embodiment of the method which transmits the vehicle association zugehö ^¬ engined vehicle, a telegram with at least the vehicle identifier to the vehicle engine. In addition to the vehicle identification, the telegram may optionally contain further information, for example in the form of status information of the vehicle. Corresponding status information may be, for example, safety-relevant data such as brake pressure, temperature or other physical measured variables of the vehicle or its charge.

In a particularly preferred development of the method which transmits the vehicle association zugehö ^¬ engined vehicle, the telegram in predetermined regular time intervals loan, on request of the traction unit and / or si ^¬ tuationsabhängig to the traction unit. By entspre ^¬-reaching transmission of the telegram at regular intervals is advantageously ensured that the traction unit receives regular feedback of the vehicles of the vehicle association. In this case, the time interval in which a corresponding feedback occurs, advantageously predetermined. This means that the concerned zeitli ^¬ che distance, for example in the form of a configuration Para ^¬ meters of a control device of the respective vehicle, such as a function of the type of the respective vehicle, pre ^¬ may be passed. In addition, however, it is also possible that the respective time interval is predetermined by the traction vehicle. So it is conceivable, for example, that the traction vehicle depending on the state of the Vehicle association, ie, for example, depending on whether the determination of the vehicles associated with the vehicle association is completed, and / or depending on the position of the vehicle in the vehicle association individually for each of the vehicles specifies the time interval. Thus it can be determined, for example, that the last movement of the vehicle ^¬ convincing association reports at shorter intervals than the other vehicles in the vehicle by means of association of the telegram with the train. As a result, a separation of the vehicle association on the basis of the absence of a corresponding telegram is advantageously faster he ^¬ known. In addition, there is advantageously additionally or alternatively the possibility that the vehicle belonging to the vehicle association transmits the telegram to the traction vehicle on request of the traction vehicle and / or depending on the situation. In the context of a situation-dependent transmission of the telegram can be, for example, upon detection of an error or the deviation of a physical variable from a predetermined range of values, the traction vehicle by means of telegram informed of the occurred situation.

Preferably, the inventive method can also take place so ^¬ that an acknowledgment of receipt to the vehicle is transmitted from the power car according to reception of the message ^¬ program. This offers the advantage that the vehicle is informed of which he ^¬ cessful transmission of the telegram. Dar ^¬ beyond can be the vehicle for example, signaled by means of the acknowledgment that the part of the traction unit further telegrams are, for instance in regular time intervals loan desired.

In a further preferred embodiment, the method according to the invention is configured in such a way that on the vehicle side, if the acknowledgment of receipt is missing, an inactive one Operating mode is changed in the telegrams are transmitted only on An ^¬ request from the traction unit and / or at greater time intervals to the traction unit. This offers the advantage that in particular under the provisions of the vehicles of the vehicle Association mens such vehicles that get on a signal sent from them telegram with their Fahrzeugken- voltage of the locomotive no acknowledgment of receipt can see that they are not part of the Driving ^¬ convincing union and use it to save energy. This concerns, for example, those vehicles which are parked on neighboring tracks, for example in the case of a vehicle association in the form of a train in a marshalling yard.

The invention furthermore relates to a drive-vehicle-side communication device for communicating with at least one vehicle-side communication device.

With regard to the drive-vehicle-side communication device, the present invention has the object to provide a communication device of the aforementioned kind, which is a particularly simple and efficient method for operating a vehicle association with a traction vehicle and at least one vehicle and Ermit ^¬ teln the affiliation of the vehicle to the vehicle association supported.

In a entspre ^¬ sponding measuring device may be o-, for example, a receiver of a satellite-based navigation system, that is, for example, a GPS receiver, a motion sensor of the act a Doppler radar speed determination. Then an appropriate measuring device before ^¬ allowed geous enough, a statement as to whether the vehicle in question is part of the vehicle association or not. Preferably, the drive-vehicle-side communication device according to the invention can also be designed such that the transmission device is designed for data transmission via a radio network. As a result, the necessity of a wired data transmission between the drive-vehicle-side communication device and the vehicle-side communication device is advantageously avoided. With regard to further advantages of this embodiment of the drive-vehicle-side communication device, reference is made to the statements in connection with the corresponding preferred development of the method according to the invention.

In a further particularly preferred embodiment, the drive-vehicle-side communication device is configured in such a way that the control device in a vehicle association with a plurality of vehicles based on the values determined by the vehicles of the measured variable for determining the last vehicle of the vehicle association and / or the ranking of ^Fahr¬ vehicles in the vehicle association is trained. This advantageously makes it possible to determine information about the structure of the vehicle association and if necessary to ver ^¬ work, to exploit and / or output.

Preferably, the drive-vehicle-side communication device according to the invention for receiving and evaluating a telegram is formed with at least the vehicle identifier of the vehicle-side communication device of the belonging to the vehicle association vehicle. Here, the Te ^¬ telegram advantageously both security and non-security may include data. Advantageously ^¬ legally thus available, the corresponding data part of the locomotive-side communication means available, optionally also a forwarding of the relevant data from the engine-vehicle communication onseinrichtung can be done to a central control or control device. Such a forwarding can take place via any known type of data transmission between a traction vehicle and a central guidance device or point.

Preferably, the powered onboard Kommunikationsein ^¬ direction may also for transmitting the transmission frequency of the telegram predetermining instruction message to the vehicle-side communication device and / or for interrogating the

Telegram be formed by the vehicle-side communication device. With regard to the advantages of this embodiment of the drive-vehicle-side communication device according to the invention, reference is made to the above statements in connection with the corresponding preferred development of the method according to the invention.

The present invention furthermore relates to a vehicle-side communication device for communicating with at least one drive-vehicle-side communication device.

With regard to the advantages of the vehicle association according to the invention, reference is made to the corresponding explanations above.

In the following the invention will be explained in more detail by means of exemplary embodiments. This shows

Figure 1 is a schematic representation of an embodiment of a vehicle dressing of the invention with an embodiment of a traction unit according to the invention as well as egg ^¬ nem embodiment of invention ^shown SEN vehicle and

Figure 2 for explaining an embodiment of the method according to the invention is a schematic

Representation of a track system of a freight yard with a locomotive and a Viel ^¬ number of vehicles.

Figure 1 shows a schematic representation of an embodiment of a vehicle assembly according to the invention with an embodiment of a traction vehicle according to the invention and an embodiment of a vehicle according to the invention. Shown is a vehicle body 200 in shape a freight train with a traction unit 10 in the form of a Lo ^¬ komotive of the goods train, and a vehicle 110 in the form of a goods wagon.

The traction unit 10 has a drive-vehicle communi cation ^¬ device 15 with a measuring device 20 for motive-vehicle determining a value of at least one kinematic measurand. At the respective measuring means 20 may, for example, a motion, nigungs- accelera- or vibration sensor and / or a device for determining the velocity of the traction unit 10 han ^¬ spindles.

Connected to the measuring device 20 is a control device 30, which is designed to receive and evaluate the measured variable determined by the measuring device 20. In addition, the control device 30 is connected to a transmission device ^¬ 40th The transmission device 40 has an antenna 50, via which signals or telegrams can be received by a vehicle-side communication device 115 of the vehicle 110. Furthermore, the locomotive-side Kommunikationsein ^¬ direction 15 a GPS (Global Positioning System) receiver 60, that is a receiver of a satellite-based Navigati- onssystems on. This makes it possible at any time to make an accurate determination of the position of the traction unit 10. In addition, the generally available temporal information is available through the satellite-based navigation data received. This makes it possible, for example, to determine the arrival time of the traction vehicle 10. This can be done, for example, by the fact that the measuring device 20 in the form of an acceleration sensor transmits a corresponding signal to the control device 30 and uses the same in the form of a GPS signal. Receiver 60 contained time the arrival time of the traction vehicle 10 determined.

Typically, the vehicle body 200 will consist of the locomotive 10 and a plurality of vehicles 110. This is indicated in the illustration of FIG 1 through the corresponding points between the running engine 10 and the driving ^¬ generating 110th It is further assumed that each of the vehicles of the vehicle association, ie each of the freight wagons, is equipped in accordance with the illustrated vehicle 110.

The vehicle 110 has a measuring device 120, which preferably determines the value of the kinematic measured variable in the same way as the measuring device 20 of FIG

Traction vehicle 10. In addition, the vehicle 110 has a control device 130, a transmission device 140 with an antenna 150 and a GPS receiver 160. The devices in question correspond in their function substantially to the corresponding components of the traction vehicle 10, wherein the control device 30 of the drive ^¬ vehicle 10 in its functionality is usually more efficient ^¬ capable than the control device 130 of the vehicle 110 will be.

Within the vehicle 200, an association between Kommunikati ^¬ on the vehicle-side communication device 115 and the locomotive-side communication device 15 can now proceed. This will be explained in more detail below with reference to FIG.

Figure 2 shows an illustration of an embodiment of the method according to the invention is a representation of a track system of a freight yard with a traction unit and a Variety of vehicles. The freight yard has branching lanes RG1 to RG9 and bypassing lanes UG1 and UG2 from a lane ALB. In the goods station there are vehicles W1-W65 in the form of freight cars and arranged on the directional track RG7 locomotive Ll in the form of a locomotive. The locomotive Ll forms together with the vehicles W35 to W41 a vehicle association in the form of a freight train. In this case, the locomotive Ll and the vehicles W35 to W41 are each constructed in accordance with the representation of FIG. 1, ie within the vehicle association a communication takes place via a radio link. The corresponding radio range FR of the communication device of the traction unit Ll is indicated in Figure 2 by a corresponding circular segment. Here, it can be seen that due to the radio range FR the locomotive Ll not only on ^¬ construction of a communication link with the vehicles W35 to W41 of the vehicle association, but is also formed with a plurality of other vehicles, who are in the area of the freight station, , This means that the part of the traction unit Ll can be no way out of it ^¬ assumed that all vehicles be located within the wireless range FR belonging to the vehicle Association of the traction unit Ll.

In order to make it possible to make a statement regarding the affiliation of the vehicles to the vehicle association and, in addition, a series determination of the vehicles, the vehicle-side communication devices of all the vehicles equipped accordingly send out a telegram at regular intervals, which of all reachable drive-side communication devices of the possible locomotives, ie the locomotives within the radio range of the respective vehicle-side communication device is received. To avoid possible collisions and thus connected error in the transmission takes place the sending of the telegrams from the different vehicles here advantageously each at different times. In this case, the telegram as a vehicle identifier and a time stamp of the last valid GPS data set, the last determined valid GPS position, contain the last be ^¬ voted speed, the last travel expenses or state direction and, where appropriate, its latest travel time ^¬ point of the respective vehicle.

The method can now proceed, for example, in such a way that the telegrams which are transmitted by the vehicle-side communication devices of each of the vehicles and received by the drive-vehicle-side communication device of the traction vehicle L1 are first of all evaluated and the received data records are registered in a "provisional vehicle list" This can be done, for example, by the fact that data records which have not yet been added to the provisional vehicle list of registered vehicles and possibly updated data records of already registered vehicles.The corresponding provisional vehicle list thus contains vehicle identifications of all vehicles within the radio range FR of the drive-vehicle-side communication device of the traction unit Ll In the further course of the method, it is now determined which of these vehicles actually belongs to the vehicle group with the locomotive Ll.

In a first step of checking the membership of the vehicles to the vehicle combination can be determined whether the vehicle in question is in general within a predeterminable prior ^¬ distance from the locomotive Ll. If this is not the case, ie the distance between the relevant vehicle-side communication device and the driveline-side communication device at- For example, exceeds the maximum allowable length of a Fahrzeugver ^¬ bands, so no receipt confirmation is generated and sent by the driveline side communication device. However, the vehicle in question and the traction unit is within the limit Entfer ^¬ voltage range, the provisional vehicle list is sorted by the distance between the vehicles and the train and evaluate the next step of the plausibility check. The preliminary vehicle list thus becomes a "provisional ranking list".

In a second step, it can be checked whether the driving condition of the respective vehicle coincides with that of the traction vehicle. If a vehicle has a speed while the traction unit Ll is at the same time, no acknowledgment of receipt is generated and transmitted on the part of the traction vehicle-side communication device.

If the running state for at least one vehicle is in agreement, then changes the locomotive-side communication ^¬ device of the traction unit Ll advantageously from egg ^¬ nem operation "standby" mode in an operating mode "Zugehö- rigkeits- or ranking determination" and acknowledges the entspre ^¬ sponding vehicle-side communication device the recom- start of the telegram with a corresponding Empfangsbestäti ^¬ supply. The locomotive-side Kommunikationsein ^¬ direction of the traction unit Ll has the ability to parameterize within the receipt, the frequency of telegrams sent from the subject vehicle individually for each of the vehicles. This makes it possible, for example, for the transmission frequency of the vehicle-side communication device of the potentially last vehicle of the vehicle association to be greater than that of vehicle-side communication devices of the vehicles within of the vehicle association. In addition, the be ^¬ signed embodiment of the method according to the invention advantageously the transmission frequency of vehicle-borne communication facilities in operation module under "hörigkeits- or conces- ranking determination" greatest.

If the vehicle-side communication device of a vehicle receives an acknowledgment of receipt for the first time, then the relevant vehicle-side communication device is likewise set to the operating mode "standby" in the operating mode "rowing determination". Provided that the vehicle-side communication device in the vehicle receives an acknowledgment of receipt of the same potential traction vehicle once again on a telegram out so the relevant vehicle-side communication ^¬ device switches from the operating mode "of belonging or Rei ^¬ hung determination" in the operating mode "Operation" in which The reason for this is that the radio link is provided between the two subscribers, ie the traction vehicle-side communication device of the traction vehicle Ll is the corresponding vehicle-side communication on ^¬ direction.

Remain more receipts of the communication equipment of the traction unit Ll to a potential for generating driving joined ^¬ belonging to the vehicle, for example, resulted in a negative plausibility check on the other hand, so changes the on-vehicle communication device of the respective

Vehicle after a predetermined time automatically from the operating mode "membership or ranking determination" back to the operating mode "Standby". In the described embodiment, the closing off ^¬ determining the affiliation of the vehicles to the vehicle Association for reasons of accuracy and reliabil sigkeit ^¬ takes place only after reaching the vehicle dressing. Thus, those vehicles of the vehicle association are highlighted by hatching in Figure 2, which have been recognized as belonging to the vehicle association after appropriate approach. This includes in the exemplary embodiment, an identifica tion ^¬ the vehicles in question, for example by means of a vehicle identification, with a. The communication devices of these vehicles are in the operation mode "Operation" after completion of the plausibility check, ie after completion of the verification of the affiliation of the vehicles to the vehicle association.

In the context of the final and decisive step of determining the affiliation of the vehicles to the vehicle ^¬ association are recognized when detecting a journey of the vehicle association as kinematic parameters, the arrival times, the speeds and / or the change in the distances between the communication devices. In this case, the values of the detected measured variables are transmitted by the vehicle-side communication devices to the drive-side communication device. The latter makes a comparison of the received values of the measured variables with corresponding values determined by the drive vehicle and determines from this which of the vehicles belong to the vehicle association. Insofar as the type of measured variables used and the respective measuring accuracy allow this, advantageously a simultaneous determination of the ranking of the vehicles of the vehicle association takes place. This results in the embodiment of Figure 2, starting from the Triebfahr ^¬ zeug Ll to W35, W36, W37, W38, W39, W40, W41, where it is at the same time, the relevant reference symbols can be the vehicle identification of the relevant vehicle.

Although the vehicle W42 is in the same directional track RG7, it is not connected to the vehicle association belonging to the traction unit Ll, that is, it is coupled. When approaching the vehicle association, the distance between the traction unit Ll and the vehicle W42 consequently becomes larger. The same applies to the vehicles in the neighboring tracks. In addition, the starting time as well as the speed and ^{acceleration of} these vehicles also deviate from those of the vehicles of the vehicle association. Thus, it enables fahrzeugsei- term and drove-vehicle determining at least one ki ^¬ nematic measure and the comparison of the advertising found te, only then assign a vehicle the vehicle association to ^¬ or to recognize as belonging to the vehicle association, if the comparison indicates a match. It is not necessary for a match ei ^¬ ne identity of the measured variables determined. For example, to take into account that there may be differences between the travel time points of the leading vehicle and the other vehicles in the order of several seconds as in a freight train ^¬ a length of 750 m. Depending on the measuring accuracy, these differences in the arrival times can advantageously be used in connection with a determination of the sequence of the vehicles belonging to the vehicle group.

According to the previous versions, the communications are tion facilities belonging to the vehicle Association vehicles W35-W41 and the traction unit Ll with a geeigne ^¬ th sensor and an appropriate logic for starting is detected equipped. As a sensor, for example, a micro-vibration sensor can be used. As part of a on the In this case, for example, a repeated interrogation and evaluation of the GPS data as a result of the response of the sensor can take place. The speed of two consecutively detected GPS data records for a journey must be greater than zero and increasing. As a result, the affiliation to the vehicle association can be determined beyond doubt even if several vehicles are behind each other, but not all belong to the vehicle association. The time of approach can be detected and stored as a time stamp ge ^¬ . This time stamp can for example be at ^¬ calculates hand the internal time stamp in the determination of the last valid GPS data set and to the detection of the approach elapsed internal time.

At the end of the process is the part of the ^{locomotive-¬} communications device a complete tire hung list with all belonging to the vehicle driving Association ^¬ witness or vehicle-mounted communication device available. If, in the future, a telegram with the vehicle identification is received by a corresponding vehicle-side communication device by the vehicle-side communication device, this answers the drive-vehicle-side communication device by a corresponding acknowledgment, whereby the relevant vehicle-side communication device is kept in the operation mode "operation" . Stay such acknowledgments, however, so takes place after a predetermined time period, the resolution of the communication link or the allocation to the vehicle combination, that is substituted, for example, the Lö ^¬ research of existing ranking list. Furthermore, the respective vehicle-side communication device automatic ^¬ table from the operating mode "operation" back in the operating mode "Standby", for example in the case that the Vehicle Association is resolved and therefore a corresponding communication link between the vehicles W35-W41 and the locomotive Ll is no longer required.

The above-described embodiment of the erfindungsge ^¬ MAESSEN method has the advantage that in particular in a wireless communication by means of a radio transmission between the locomotive and the vehicles of a vehicle association, a determination of the ranking of the vehicles of the vehicle association without a continuous line within the vehicle association is made possible. Simultaneously, a determination of the associated to the vehicle Association vehicles and the ranking of these vehicles advantageously intra ^¬ half of the vehicle association itself is possible, ie a transmission of a corresponding ranking list, for example, from a central control, is not required. Nevertheless, a comparison of the determined series list with a corresponding scheduled vehicle list, which can be received, for example, on the drive side by a control center, in principle, of course, additionally possible.
