Abstract

A method for operating rail vehicles in an operational area of a traffic network that is shared with traffic participants other than the rail vehicles. The rail vehicles communicate with line elements arranged in the operational area. Here, the rail vehicles and the line elements use a V2X standard for communication between each other within the shared operational area. In an operational area that is reserved for the rail vehicles, the rail vehicles communicate with the line elements via a communication standard that is different from the V2X standard.

First claim

The invention claimed is:

1 . A method for operating a rail vehicle (FZ) in a traffic network, the method comprising:
providing a shared operational area that is shared with traffic participants other than rail vehicles, wherein the rail vehicle is configured to run on sight without automatic train protection; providing a reserved operational area reserved for rail vehicles, wherein the rail vehicle is configured to operate according to a central rail monitoring and operational management having an automatic train protection; communicating between the rail vehicle and line elements arranged in the shared operational area by using a V2X standard for communication in the shared operational area shared with traffic participants other than rail vehicles; and communicating between the rail vehicle and line elements arranged in an operational area reserved for rail vehicles by using a communication standard different from the V2X standard for communication.

2 . The method according to claim 1 , which comprises using a Cooperative Awareness Message of the V2X standard for communication.

3 . The method according to claim 1 , wherein the line elements, which use the V2X standard, are modified to use a processing unit, which converts a message received according to the V2X standard into converted control commands for a control member or generates control commands from the received message and in both cases transmits the control commands to a controller for the respective control member, and wherein the controller actuates the control member using the control commands.

4 . The method according to claim 3 , wherein the converted control commands have a syntax which matches a syntax of specific line elements developed for the relevant control member.

5 . The method according to claim 4 , which comprises using the modified line elements and the specific line elements in the shared operational area.

6 . The method according to claim 1 , which comprises replacing specific line elements that are permanently fitted in a track body of the traffic network.

7 . The method according to claim 6 , which comprises replacing specific line elements that are embedded in a road surface surrounding the line.

8 . The method according to claim 6 , which comprises using modified line elements fitted outside of the track body.

9 . A traffic network for operating rail vehicles, the traffic network having an operational area shared with traffic participants other than the rail vehicles, the traffic network comprising: line elements configured to carry out the method according to claim 1 .

10 . A rail vehicle for operation in a traffic network having an operational area shared with traffic participants other than the rail vehicle, the rail vehicle being configured to carry out the method according to claim 1 for communicating with a line element of the traffic network.

11 . The rail vehicle according to claim 10 , wherein the line element is a modified line element.

12 . A processing unit for operation in a traffic network having an operational area shared between traffic participants that include rail vehicles and traffic participants other than the rail vehicles, the processing unit being configured to carry out a method according to claim 1 to process signals in a line element.

13 . A computer program comprising non-transitory program commands for carrying out the method according to claim 1 when the program commands are executed on a computer.

14 . An apparatus for providing the computer program according to claim 13 , wherein the apparatus is configured for storing and/or providing the computer program.

15 . A method of modernizing an operational area for rail vehicles, wherein the operational area has control members, which are actuated by line elements using control commands, the method comprising:
for modernizing the operational area, successively replacing line elements specific to the relevant control member and fitted in a line of the operational area with modified line elements; configuring a processing unit of the modified line elements, the processing unit converting a message received in accordance with one communication standard into modified control commands for a control member or generating control commands from the message and in both cases transmitting the control commands to a controller for the respective control member, and actuating the control member with the control commands; the control commands having a syntax, which matches a syntax of specific line elements fitted in the line for the rail vehicle; and using the modified line elements having a processing unit and specific line elements in the shared operational area.

16 . The method according to claim 15 , which comprises using a V2X standard as the communication standard.

17 . The method according to claim 15 , wherein the operational area lies in a traffic network which is shared with traffic participants other than the rail vehicles.
