- Figure 4 shows an embodiment of the method according to the invention, in which an embodiment of the vehicle 11 according to the invention. Identical or functionally equivalent elements are provided with the same reference numerals as in relation to Figures 1-3.
- the front area 18 is detected by the first detection device 20 and it is detected by the first detection device 24 that several objects 34 are located on the route 6.

- the vehicle 3 shown at the top in Figure 6 forms a vehicle group, the integrity of which is determined by means of a physical loop (the integrity is present if the loop has no interruption).
- the vehicle 5 shown in the middle of Figure 6 is, for example, a goods transport vehicle with a locomotive and several wagons. In vehicles of this type, wiring with a physical loop analogous to the vehicle 3 is not practical.

- the vehicle 112 detects the vehicle 111 using the second detection device 28.
- the two vehicles 111 and 112 can each retrieve information about the coupled vehicle from a database. In this way, information from a train inauguration of a vehicle group formed by vehicles 111 and 112 can be confirmed via the respective recognition of the coupling partner. For example, information from an electronic train christening can be compared with the information obtained through recognition.
- the vehicle 112 moves away from the stationary vehicle 111 in the direction of travel 14. The vehicle 112 detects the rear area 19 using the second detection device 22 and detects the vehicle 111 and the increasing distance between the vehicles 111 and 112 using the second detection device 28. In this way, the separation of the vehicles, which has already been recognized, for example, by an electronic coupling signal, is confirmed by the object recognition after decoupling.
- the vehicle 111 shown in FIG. 8 is a sub-vehicle of a plurality of sub-vehicles 111, 112 that can be coupled to one another and can together form a vehicle group.
- the other sub-vehicle 112 of the vehicle group is recognized as the object. Based on the detection, the further sub-vehicle 112 is identified and it is determined whether the further sub-vehicle is coupled to the vehicle 111.
- the method steps described show that the determination of train integrity is improved by the method according to the invention by combining information from different sources (electronic train inauguration, database content, object recognition).

- the respective vehicle can determine its location and orientation based on the recognition of the detected objects 930.
- a second application occurs when the vehicles 911, 912, 913 are parked at a smaller distance from one another in such a way that they can at least partially recognize each other. In this way, the respective vehicle can use the detection to determine which other vehicles it is standing next to and/or between. Management can use this knowledge to determine which vehicles are “parked” and in what order the vehicles can be moved.
- a third application is the location of a vehicle 911, 912 or 913 after it was moved to the switched off state (so-called cold movement detection). By detecting objects 930 in the surrounding area, the displaced vehicle can determine its location alone or in addition to a GPS signal.
- Figure 10 shows a further embodiment of the method according to the invention, in which an embodiment of the device according to the invention is used. Identical or functionally identical elements are provided with the same reference numerals as in relation to Figures 1-9.

- a method step BB after the vehicle has passed the object 1030, the object 1030 is recognized within the rear area 19 by means of the second recognition device 28 of the same vehicle 1011.
- the object 1030 is recognized within the rear area 19 at a time after it has already been recognized as an object within the front area 18.
- the object properties of the object 1030 recognized within the front region 18 and the object properties of the object 1030 recognized within the rear region 19 are brought together in a method step CG in order to determine combination properties of the object 1030. This combination is illustrated in FIG. 10 by a schematic representation of an enlargement through a magnifying glass 1031.
- the respective object property is, for example, a two-dimensional silhouette of the object 1030 (from the front and from the back).
- the combination property is, for example, a three-dimensional contour of the object 1030. This contour can be taken into account when operating a subsequent vehicle 1012 in a method step DD and for improved recognition of the object 1030 by the further Vehicle 1012 can be used. This is helpful, for example, if the other vehicle 1012 detects the object 1030 in a changed orientation.
