- Rail vehicle that is suitable for driving on the railway track system according to Figures 1-8.
- FIG. 1 shows a railroad track system 10 which comprises a passenger transport area 11 and a depot area 12.
- the passenger transport area 11 has two tracks 111 and 112, which are equipped with three stops or train stations 113a, 113b and 113c.
- the passenger transport area 11 has a large number of trackside devices which enable an autonomously drivable rail vehicle to operate autonomously.
- the trackside facilities for this autonomous ferry operation are not shown in more detail in FIG. 1 for the passenger transport area 11 for reasons of clarity.
- the depot area 12 of the railroad tracks 10 has three sidings 121, 122 and 123.
- the sidings or the depot area 12 as a whole are also equipped with track-side devices which enable an autonomously driving rail vehicle to operate autonomously; the trackside facilities in the depot area 12 are symbolized in FIG. 1 by circles, three of which are indicated by way of example with the reference numerals 124a, 124b and 124.
- the trackside devices 124 can be, for example, track circles or balises placed in the track bed of the railroad track system 10.
- the depot area 12 is also equipped with a monitoring device 30 which enables the depot area 12 or at least sections of the depot area 12 to be monitored.
- the monitoring device 30 is equipped with cameras 31, the camera signals KS of which are evaluated by an evaluation device 32 of the monitoring device 30.
- the monitoring device 30 is connected to a higher-level control center 40, for example.
- an autonomously drivable rail vehicle 20 is located on the siding 123 and is parked there.
- FIG. 2 shows a person capable of driving the rail vehicle 20, hereinafter referred to as the vehicle driver FF for short, who is located in the station 113b of the passenger transport area 11.
- the vehicle driver FF would like to put the rail vehicle 20 into operation and, as part of an autonomous ferry operation, drive it to the station 113b forming the transfer point, where he would like to take the rail vehicle for further travel.
- the vehicle driver FF generates a request signal AS, which he transmits, for example, by radio to the rail vehicle 20 parked in the depot area 12.
- the rail vehicle 20 After receiving the request signal AS, the rail vehicle 20 generates a request A (see FIG. 3), which it sends to the monitoring device 30 on the spot. With inquiry A, the rail vehicle asks whether it is allowed to drive into the depot area autonomously or not. After receiving request A, the depot-side monitoring device 30 uses the camera signals KS of the cameras 31 to check whether the depot area 12 as a whole or at least the section 200 is free and can be driven through by the rail vehicle 20 in an autonomous auxiliary driving mode without endangering it.
- the rail vehicle 20 may not initially travel in an autonomous ferry mode after being put into operation, but must first be operated in an autonomous auxiliary travel mode. Switching from the autonomous auxiliary driving operation to the autonomous ferry operation should only be possible or permitted when the rail vehicle 20 - starting from the stopping position shown in FIGS. 1 to 4 - has passed the first and second trackside devices 124a and 124b.
- the route section 200 which extends from the stopping position to the second route-side device 124b, should first be driven through in the autonomous auxiliary driving mode; Only then should the rail vehicle 20 switch to the autonomous ferry operation and be allowed to travel in this through the remaining depot area 12 in the direction of the passenger transport area 11.
- the monitoring device 30 determines that the route section 200 up to the second route-side device 124b is free or can be driven through without danger, it generates a release signal FS on the output side, which signals the drivability.
- the release signal FS is transmitted from the monitoring device 30 to the rail vehicle 20 (see FIG. 4).
- the rail vehicle 20 As soon as the rail vehicle 20 has received the release signal FS, it sees the request signal AS as a travel command and begins its journey in the direction of the passenger transport area 11 to the station 113b, which is used as the destination, for example is indicated in the request signal AS.
- the rail vehicle 20 in the route section 200 that is to say until it passes the second route-side device 124b, will initially travel in autonomous auxiliary driving mode.
- the autonomous auxiliary driving mode it will ignore signals which it receives from the two trackside devices 124a and 124b or other trackside devices and which indicate, for example, maximum permitted speeds (see FIG. 5) and preferably a fixed maximum speed for the autonomous auxiliary driving mode do not exceed.
- the second trackside device 124b Only after passing the second trackside device 124b (see Figure 6) will it switch to the autonomous ferry operation and in this - in a known manner using or observing control signals received from trackside devices 124 and, for example, maximum speeds specify - drive through the depot area 12 into the passenger transport area 11 and to the train station 113b. As soon as it has reached the station 113b, the vehicle driver FF can take over the rail vehicle 20 and continue from there.
- the request signal AS is generated by the control center 40 and transmitted to the rail vehicle 20 (see FIG. 7).
- the rail vehicle 20 can inquire from the monitoring device 30 (inquiry A) whether the route section 200 can be driven on and the journey in the direction of the passenger transport area 11 - as described in connection with FIGS. 1 to 6 - can take place; and the monitoring device 30 can, if necessary, generate the release signal FS.
- control center 40 forwards the request signal AS directly to the monitoring device 30, which after checking the drivability of the depot area 12 or the route section 200, the release signal FS together with the request signal AS as Travel command FB is transmitted to rail vehicle 20 (see FIG. 8).
- FIG. 9 shows an exemplary embodiment for the rail vehicle 20 according to FIGS. 1 to 8 in greater detail.
- the rail vehicle 20 has a vehicle control device 210 which comprises a computing device 211 and a memory 212.
- a driving module ATO is stored in the memory 212, which when executed by the computing device 211 enables an autonomous ferry operation, as is generally known in the field of railway technology, in particular in the field of rail-bound local transport.
- an auxiliary module HM is stored in the memory 212, which when executed by the computing device enables an autonomous auxiliary driving mode in which - unlike in the autonomous ferry operation - control signals transmitted by trackside devices are disregarded and preferably independent of received control signals The maximum speed specified for the autonomous auxiliary drive is not exceeded.
- a control module SM is designed to first activate the autonomous auxiliary driving mode, i.e. the auxiliary module HM, and only switch from the auxiliary module to the driving module ATO when a specified switchover condition is met, for example after starting up in the autonomous auxiliary driving mode, a specified number In the railway track system 10 attached track-side devices 124a and 124b (z.
