Description

[0001] DESCRIPTION

[0002] Decentralized door device of a rail vehicle

[0003] The invention relates to a door device of a rail vehicle according to the preamble of claim 1. Furthermore, the invention also relates to a rail vehicle with such a door device according to claim 20.

[0004] Currently, electrical components (sensors / actuators) in the movable door leaves of door devices (entry systems) are connected discretely (individually) to a central door control system. This signal connection is established either via separate signal lines and / or via a bus system in which the individual signals are bundled for transmission. This requires continuous transmission of all input and output signals between the individual components in the door leaf(s) and the central door control system, as the control logic of these components is entirely implemented in the central door control system.

[0005] This design results in high cabling costs between the components in the door leaf(s) and the central door control, high demands on signal processing in the central door control, and increased sensitivity to interference in the communication between the components and the central door control.

[0006] A generic door device is known, for example, from DE 20 2021 102 331 U1. There, a central door control unit arranged on a drive support of the door frame is connected via a power chain and a cable arrangement arranged in the power chain, as well as a distribution device, to various actuators arranged in or on a door leaf of a door device, such as a sound module, a passenger button, and a radiator.

[0007] The present invention, in contrast, is based on the object of providing a door device that reduces the complexity of the central door control system and, moreover, allows for less complex cabling and data transmission. Likewise, a rail vehicle with at least one such door device is to be provided.

[0008] This object is achieved according to the invention by the features of claims 1 and 20. Disclosure of the invention

[0009] The invention is based on a door device of a rail vehicle, at least comprising: a) at least one door frame with at least one door opening, b) at least one door leaf driven relative to the at least one door frame by at least one door leaf drive, for opening and closing the at least one door opening, c) at least one first door control which provides a first part of functions of a door leaf operation or door leaf actuation control of the at least one door leaf and which is arranged outside the at least one door leaf, in particular on the at least one door frame.

[0010] A rail vehicle is defined as a track-bound vehicle traveling on a track, such as a subway, a commuter train, a tram, or a carriage or railcar of a train. The door leaf can be a sliding door leaf with a pure translational degree of freedom or a combined sliding / swinging door leaf with a translational and rotational degree of freedom. The rail vehicle is particularly part of local or long-distance public transport.

[0011] The first door control can control at least one door leaf, which can open or (partially) close a single door opening. In this respect, the first door control can provide the first part of the functions of the door leaf operation or door leaf actuation control of at least one door leaf, which is assigned to a single door opening. In this respect, for example, a separate first door control can be provided for each door opening of the rail vehicle, which then provides the first part of the functions of the door leaf operation or door leaf actuation control of at least one door leaf, which is assigned to the respective door opening. Furthermore, the first door control can also be provided to provide the first part of the functions of the door leaf operation or door leaf actuation control of several door leaves, which are assigned to different door openings or open and close them.The first part of the functions of the door leaf operation or door leaf actuation control, which is provided by the first door control, comprises in particular a (direct) control or regulation of the at least one door drive.

[0012] The at least one first door control can then communicate with a central control of the rail vehicle, for example, with a central train control unit, in order to receive instruction signals from the central control unit, which are generated by the central control unit depending on the driving state, for example, when the rail vehicle stops, particularly at a platform, an enable signal that generally allows the door leaves to be opened, for example, by passengers. The at least one first door control can also represent or comprise a central control unit of the rail vehicle.

[0013] The invention is then characterized by d) at least one second door control which is arranged on or in the at least one door leaf or is integrated there and which provides a second part of the functions of the door leaf operation or door leaf actuation control of the at least one door leaf.

[0014] The invention therefore assumes that a first part of the functions of the door leaf operation or actuation control of the at least one door leaf is provided outside the at least one door leaf by the at least one first door control, which is arranged, for example, on the door frame and in particular controls at least one door leaf assigned to a door opening or also several door leaves assigned to different door openings. The invention then provides that a second part of the functions of the door leaf operation or actuation control of the at least one door leaf is outsourced to the at least one second (electronic) door control arranged in or on the movable door leaf.

[0015] In this case, the first door control unit can in particular represent a central door control unit, which, in particular with regard to certain functions, represents a master in a master / slave relationship between the first door control unit and the second door control unit as the slave. Equality between the first door control unit and the second door control unit is also possible, in particular with regard to certain functions. Last but not least, in particular with regard to certain functions, the second door control unit can represent the master and the first door control unit the slave. This enables decentralized control / regulation of components (actuators, sensors) of the at least one door leaf by means of the then distributed first and second parts of the functions of the door leaf operating or

[0016] This does not, however, exclude the possibility that the first and second parts of the functions of the door leaf operation or

[0017] Door leaf actuation controls can also have overlaps as long as they are not completely identical.

[0018] On the one hand, this reduces the load on the control or regulation logic of components of the at least one door leaf in the first door control system because part of the control logic (the second part) is located locally in the second door control system on or in the at least one door leaf. The second door control system, in particular, has local intelligence.

[0019] The intelligence of the second door control can consist in the fact that it evaluates a sensor signal received from at least one sensor and, depending on the sensor signal, generates an instruction signal, i.e. a command for at least one actuator in or on the door leaf. The at least one sensor is preferably arranged on or in the at least one door leaf, but alternatively also outside the at least one door leaf. Additionally or alternatively, the intelligence of the second door control can comprise an interpretation and / or implementation of an instruction signal received, for example, from the first door control and / or from the central control, for example in such a way that the second door control activates or regulates an actuator arranged on or in the at least one door leaf depending on the instruction signal. Open-loop and closed-loop controls by the second door control are therefore possible.Last but not least, due to its intelligence, the second door control can also generate an instruction signal for the first door control and / or the central control depending on a sensor signal, for example from at least one sensor arranged in or on the at least one door leaf, in order to activate or deactivate the door drive, for example.

[0020] As a result, it is no longer necessary to transmit all discrete signals between the components of the at least one door leaf (sensors, actuators) and the first door control system, since the second part of the functions of the door leaf operation or door leaf actuation control system is executed or processed in the second door control system, in particular autonomously, i.e. independently of the first door control system. This leads to a reduction in the amount of data that must be exchanged between the components (sensors, actuators) in or on the at least one door leaf and the first door control system, and thus to a reduction in potential interference. In particular, the requirements regarding the temporal dependence of the signal transmission between the first (central) door control system and the components become less critical.

[0021] The subclaims list features of advantageous developments of the invention.

[0022] Particularly preferably, the second part of the functions of the door leaf operation or door leaf actuation control comprises an evaluation of a sensor signal from at least one sensor, in particular arranged in or on the at least one door leaf, in particular also independently of the first door control.

[0023] According to a further development, the second part of the functions of the door leaf operation or actuation control can comprise generating an instruction signal for the door leaf drive as a function of the sensor signal, wherein the second door control is designed and configured to generate the instruction signal, in particular independently of the first door control. The instruction signal for the door drive can in particular represent an activation or deactivation of the door drive, for example so that the at least one door leaf assumes an open position, a closed position, or an intermediate position between the open position and the closed position. The second part of the functions of the door leaf operation or actuation control, which is provided by the second door control, therefore in particular comprises an (indirect) control or regulation of the at least one door drive.

[0024] In the sense of a “local intelligence” already mentioned above, the second door control can also be designed and configured to control or regulate at least one actuator arranged on or in the at least one door leaf with the aid of implemented control or regulation routines, in particular also independently of the first door control.

[0025] In further development of this, the second door control can then be designed and configured to control or regulate the at least one actuator arranged on or in the at least one door leaf with the aid of the implemented control or regulation routines as a function of a sensor signal from at least one sensor arranged in particular on or in the at least one door leaf, in particular independently of the first door control.

[0026] An output stage (power control) can also be arranged between the second door control and the actuator, which output stage is arranged in or on the at least one door leaf and is integrated, for example, into the second door control.

[0027] To implement the “local intelligence”, the second door control may comprise electronics with at least one microprocessor and / or at least one memory in which, in particular, an evaluation circuit for sensor signals and / or control or regulation routines are implemented.

[0028] In particular for digital communication with the first door control and / or with a central control, the second door control may comprise a digital data interface which is designed and configured for connection to a data bus.

[0029] Preferably, at least one communication device can be provided and configured to communicate instruction, status, and / or feedback signals between the first door control and the second door control. An instruction signal is to be understood as a signal with the aid of which actuators and / or further control devices arranged in or on the at least one door leaf are controlled or regulated. Status signals or feedback signals can represent the state or position of the at least one door leaf, in particular with regard to its respective position relative to the door opening (open position, closed position, intermediate position), but also a functional state of the second door control itself or of components connected to it, such as actuators and sensors on or in the at least one door leaf.This can also be understood as a signal which characterises a pinching or collision situation between at least one door leaf and an object or a person.

[0030] The communication device can be designed and configured to operate according to a multiplexing method, in which multiple signals are bundled and transmitted simultaneously over a medium. Bundling can be achieved, for example, by modulating data or signals onto a carrier signal, which is then demodulated at the receiver, particularly in the first door control, as part of a debundling process. The communication device can also be integrated into the second door control or can be a stand-alone device connected to both the second door control and the first door control.

[0031] The medium used for the communication device can comprise one or more lines, a cable, both possibly in a drag chain, a data bus and / or a radio link.

[0032] A power chain can also be provided between the at least one door leaf and an external power supply in order to supply at least the second door control and / or components installed in or on the at least one door leaf, such as actuators and / or sensors, with electrical energy. Alternatively or additionally, an electrical power supply such as a battery, an accumulator, or a capacitor can also be arranged on or in the at least one door leaf in order to supply the second door control and / or the components arranged on or in the at least one door leaf with electrical energy.

[0033] According to one application, the second door control can comprise a control of at least one display arranged on the at least one door leaf, in particular on or in a transparent door pane of the door leaf, wherein the second part of the functions of the door leaf operation or door leaf actuation control includes a control of graphics, symbols, and / or alphanumeric characters shown on the display. The second door control can in particular control at least one display in order to display graphics, symbols, and / or alphanumeric characters in an interior of the rail vehicle and / or to the outside. The graphics, symbols, and / or alphanumeric characters can in particular contain information about arrival and departure times of the rail vehicle, connecting connections, entrances and exits at platforms, etc., but also advertising.

[0034] According to a further application, the second door control can comprise a control of at least one operating unit, into which at least one actuating element for inputting door opening and / or closing commands, at least one sensor that detects actuation of the actuating element and interacts with the second door control, and at least one optical and / or acoustic signaling device are integrated, which is configured and designed to signal at least the door leaf state and / or a possible actuation of the door leaf. The second part of the functions of the door leaf operation or door leaf actuation control then comprises the control of the optical and / or acoustic signaling device and / or the door leaf drive, for example, by means of an instruction signal that is generated by the second electronic door control as a function of actuation of the at least one actuating element.

[0035] The operating unit then represents an independent operating module which in particular carries out the opening and closing control of the at least one door leaf when, for example, an enable signal has been transmitted from the central control of the rail vehicle and / or from the first door control to the second door control so that the second door control then controls or regulates the opening and closing of the at least one door leaf (only) depending on the actuation of the at least one actuating element and in particular independently of the first door control.

[0036] According to a further application, the second door control can comprise a control of at least one LED device comprising at least one LED arranged on the at least one door leaf. The LED device can, in particular, signal a possible or already completed actuation of the at least one door leaf, e.g., a green light for a possible or permitted opening or closing of the at least one door leaf, in particular by actuating the at least one actuating element of the control unit described above. Conversely, a red light can symbolize an impossibility of opening the at least one door leaf. Serial control of several LEDs arranged along a light strip to generate light bars of different lengths is also conceivable.

[0037] According to a further development, at least one brightness sensor can also be arranged on the at least one door leaf, wherein the second door control controls the at least one LED device depending on the signal of the brightness sensor.

[0038] The LED device can also backlight recesses made in a cover, which then, when illuminated by the LED device, display graphic symbols such as arrows pointing outwards, for example to signal that at least one door leaf is currently being opened or closed.

[0039] According to a further application, the second door control may comprise a contact-free control or regulation of the at least one door leaf, wherein the second part of the functions is a generation of an instruction signal for the door leaf drive depending on a signal from at least one contact-free proximity sensor arranged on or in the at least one door leaf, which is generated depending on a relative distance between a person and / or an object and the at least one proximity sensor.If, for example, a release signal has been transmitted from the central control system of the rail vehicle and / or from the first door control system to the second door control system, for example, after the rail vehicle has stopped, the second door control system can autonomously and, in particular, independently of the first (central) door control system, initiate the opening or closing of at least one door leaf (solely) depending on the signal from the at least contactless proximity sensor. Then, for example, only those door leaves in the vicinity of which a passenger or an object such as a cane is located are automatically controlled by the second door control system from the closed position to the open position.

[0040] According to a further application, the second door control can also comprise a control of an anti-pinch function or a pinch detection function, wherein the second part of the functions comprises generating a detection signal representing a pinch or collision situation depending on a signal from at least one pinch or collision detection sensor, which the sensor generates depending on a pinch or collision situation. This signal is generated, for example, when an object and / or a person's body part becomes trapped between a closing edge of the door leaf and the door frame or another closing edge of another door leaf. The pinch or collision detection sensor can, in particular, comprise a force or pressure sensor arranged in the region of the closing edge.

[0041] According to a further application, the second door control can comprise a control of a sound module arranged on or in the at least one door leaf, which outputs acoustic signals and / or acoustic information, wherein the second part of the functions of the door leaf operation or door leaf actuation control comprises a control of the sound module as a function of instruction, status and / or feedback signals from the at least one door leaf or for the at least one door leaf. In particular, the control of the sound module by the second door control can be carried out as a function of the ambient noise, which is detected, for example, by a sensor interacting with the second door control, such as a microphone. Preferably, the sensor is also arranged on or in the at least one door leaf.

[0042] In a further development, the sound module can be comprised of a detection tone generating device, which is controlled by the second door control and is designed and configured to generate an acoustic detection tone in the region of the at least one door leaf. Such a detection tone generating device serves, in particular, to make it easier for visually impaired persons to locate the door device or the at least one door leaf by means of the emitted detection tone. In particular, the detection tone generating device can be controlled by the second door control as a function of the ambient noise, which is detected, for example, by a sensor such as a microphone that interacts with the second door control. The sensor is preferably also arranged on or in the at least one door leaf.

[0043] According to a further development, several of the above-described controls can also be implemented in the second door control. The second door control can represent a single structural unit and then comprise the entire second part of the functions of the door leaf operation or door leaf actuation control. However, it is also conceivable to distribute the second part of the functions of the door leaf operation or door leaf actuation control among several second door controls, which are then arranged in or on the at least one door leaf or integrated there.

[0044] The invention also relates to a rail vehicle with at least one door device as described above, which is designed in particular for the transport of goods and / or persons in local or long-distance public transport.

[0051] Actuating device and an availability display device in a structural unit which cooperates with a double-leaf vehicle door device according to Fig. 2;

[0052] Fig. 4 is a further schematic representation of the double-leaf door device of Fig. 2.

[0053] Description of the embodiment

[0054] Fig. 1 shows a rail vehicle 300 with, for example, two double-leaf door devices 200, each of which is encompassed by an entry system of the rail vehicle 300. The rail vehicle 300 is designed in particular for passenger transport in local or long-distance public transport and, for example, as a railcar. The rail vehicle 300 has a central controller 53, which performs essential control and regulation functions of the rail vehicle 300, as well as, for example, a separate first electronic door controller 10 for each door device 200, which provides a first part of the functions of a door leaf operation or door leaf actuation control of two door leaves 5a and 5b of the respective door device 200 and which is arranged, for example, on a door frame of the respective door device 200.The door devices 200 are each designed here, for example, as prefabricated and complete door modules, each comprising a door frame, a door guide, the two door leaves 5a, 5b, and the first electronic door control 10. Such a door module can then be inserted completely into a door opening in the side wall of the rail vehicle 300.

[0055] The first electronic door controls 10 communicate, for example, via a first data bus 6 with the central control unit 53 and can also receive an enable signal via this route, which the central control unit 53 controls, in particular when the rail vehicle 300 stops at a platform, in order to enable the door leaves 5a, 5b of the door devices 200 to be opened individually by passengers, for example.

[0056] Fig. 2 shows a schematic side view of a double-leaf door device 200 of the rail vehicle 300 of Fig. 1. The double-leaf door device 200 comprises a first door leaf 5a and a second door leaf 5b. Here, the first door leaf 5a is, for example, a first sliding door leaf displaceable in a displacement direction, and the second door leaf 5b is a second sliding door leaf displaceable in the displacement direction. Consequently, the door device 200 here preferably represents a sliding door device.

[0057] The door leaves 5a, 5b carry first illuminating means 150a on their mutually facing closing edges 7a, 7b, namely on a first closing edge 7a and second illuminating means 150b on a second closing edge 7b.

[0058] Furthermore, a first door guide (not shown here) is provided, which guides the first door leaf 5a relative to a door opening on the door frame, and a second door guide (also not shown here) which guides the second door leaf 5b relative to the door opening on the door frame.

[0059] The door device 200 further comprises first and second drive devices 9a, 9b, for example, without mechanical coupling of the two door leaves 5a, 5b. A first drive device 9a comprises a first motor 1a driving a first spindle 2a, as well as a first nut / spindle drive comprising the first spindle 2a and an associated first spindle nut 3a. Similarly, a second drive device 9b comprises a second motor 1b driving a second spindle 2b, as well as a second nut / spindle drive comprising the second spindle 2b and an associated second spindle nut 3b.The motors 1a, 1b, for example, are rotary motors, which then drive the associated spindle 2a, 2b, screwing the respective non-rotatably held spindle nut 3a, 3b along the associated spindle 2a, 2b via the corresponding nut-spindle drive. Mechanical connecting elements 4a, 4b each connect a door leaf 5a, 5b to the respective spindle nut 3a, 3b. Alternatively, the door leaves 5a, 5b could also be driven directly, i.e., without nut-spindle drives, for example, by a linear motor.

[0060] The first door leaf 5a can therefore be moved by the first drive device 9a between a first open position and a first closed position, each as the end position, as well as into any intermediate positions between the first open position and the first closed position. Similarly, the second door leaf 5b can also be moved by the second drive device 9b between a second open position and a second closed position, each as the end position, as well as into any intermediate positions between the second open position and the second closed position.

[0061] The first drive device 9a and the second drive device 9b are therefore designed separately here. The first drive device 9a and the second drive device 9b are controlled jointly by a first electronic door control 10, which controls the movement of the two door leaves 5a, 5b. A first movement of the first door leaf 5a between the first open position and the first closed position in relation to a second movement of the second door leaf 5b between the second open position and the second closed position therefore occurs here, for example, without mechanical coupling between the first door leaf 5a and the second door leaf 5b. Rather, the two door leaves 5a and 5b are controlled jointly by the electronic first door control 10, then electronically coupled, or individually, i.e. independently of one another.

[0062] For example, a display device 54 is arranged in each of the two door leaves 5a and 5b, which interacts with the two-leaf vehicle door device 200 according to Fig. 2 as described below. For reasons of scale, such a display device 54 is shown in Fig. 2 only on the first door leaf 5a, but the second door leaf 5b may also be equipped with such a display device 54.

[0063] The display device 54 is part of an availability display device 50, which includes and is controlled by a second electronic door control 56. The availability display device 50 can, for example, use visual information to display the availability, or if no availability exists, the non-availability, of the two door leaves 5a, 5b with respect to the possibility of opening the two door leaves 5a, 5b, particularly when the rail vehicle is stopped at a platform.

[0064] Here, for example, combined with the availability display device 50 or with the display device 54 in one structural unit is an actuating device 51, which is also controlled by the second electronic door control 56 and which here, for example, has two actuating elements, a first actuating element 52a and a second actuating element 52b, for actuating, for example, the first door leaf 5a, and which here, for example, is also controlled by the second electronic door control 56. It is understood that the actuating elements 52a and 52b act on sensors (not shown here), which detect actuation of the actuating elements 52a, 52b and interact accordingly with the second door control 56. In Fig. 2, the second electronic door control 56 is shown separately from the structural unit in which the availability display device 50 is combined with the actuating device 51 for reasons of clarity.However, the second electronic door control 56 can also be integrated into this unit.

[0065] For example, on or at the actuating elements 52a, 52b, symbols in the form of arrows are formed, which are intended to symbolize an opening and closing direction of the door leaves 5a, 5b. By means of the actuating elements 52a, 52b, the two door leaves 5a, 5b can then be individually actuated between their respective open and closed positions, provided, however, that the second electronic door control 56 has received the release signal from the central control unit 53 that the door leaves 5a and 5b are released for actuation. Upon actuation of the first actuating element 52a of the actuating device 51, which, as can be easily understood from Fig. 2, symbolizes, for example, the opening direction of the first door leaf 5a, an opening signal is then fed into the second electronic door control 56, where it is processed and, for example, also digitized.

[0066] The second electronic door control 56 is connected to the first electronic door control via a second data bus 57. Since the second electronic door control 56 is integrated into the movable door leaf 5a, the second data bus is preferably integrated into a drag chain cable (not shown here). The second electronic door control 56 also receives the release signal from the first electronic door control 10 via this second data bus 57, so that an actuation of the first door leaf 5a by a passenger using the actuating device 51 or, here, for example, by the first actuating element 52a, is even possible.

[0067] Also via the second data bus 57, the second electronic door control 56 then controls a first actuation signal S1 for actuating the first door leaf 5a into the first electronic door control 10 in response to the opening signal, which then controls or activates the first motor 1a accordingly in order to move the first door leaf 5a from the closed position to the open position.

[0068] The two door leaves 5a and 5b can therefore be operated separately, for example, by their own actuating device 51. For example, viewed in the operating position of the actuating device 51, the first, here for example left, actuating element 52a then actuates the first door leaf 5a into the open position, and the second, here for example right, actuating element 52a actuates the first door leaf 5a into the closed position. In an analogous manner, but mirrored, the second door leaf 5b is controlled by its own actuating device (not shown here).

[0069] As explained above, in the embodiment of Fig. 2, the display device 54 and the operating device 51 form a structural unit which is arranged on or in the door leaves 5a and 5b and is jointly controlled, for example, by the second electronic control 56.

[0070] Here, for example, the second electronic door controls 56 integrated in the door leaves 5a, 5b can receive, in particular from the first electronic door control 10 or from the central control 53, a first availability signal V1 for the availability of the first door leaf 5a or a first unavailability signal NV1 representing the unavailability of the first door leaf 5a with regard to an actuation of the first door leaf 5b, and separately therefrom a second electrical availability signal V2 representing the availability of the second door leaf 5b or a second unavailability signal NV2 representing the unavailability of the second door leaf 5b with regard to an actuation of the second door leaf 5b. This then means that the door leaf 5a or 5b in question can be opened or closed despite actuation of the relevant actuating device 51 orof the first actuating member 52a remains in its closed position and cannot then be opened.

[0071] The first and second availability signals V1 and V2 can generally be generated when the rail vehicle 300 is at a standstill or at a platform, and then, after generating a general release signal for the door leaves 5a, 5b, there is additionally no fault in the door leaves 5a, 5b, the motors 1a, 1b and in the respective drive trains which mechanically connect the door leaves 5a, 5b to the motors 1a, 1b.

[0072] However, if, for example, due to wear between the first spindle 2a and the associated spindle nut 3a, a current exceeding an upper limit current flows through the first motor 1a, the first electronic door control 10 registers this and then generates the first unavailability signal NV1. This first unavailability signal NV1 does not allow the first motor 1a to be controlled by the first actuation signal S1 for actuating the first door leaf 5a, which is generated by the second electronic door control 56 and fed into the first electronic door control 10 via the second data bus 57. With the result that the first door leaf 5a remains in the closed position and can then no longer be opened in order to prevent the first door leaf 5a from jamming during further actuation.

[0073] The first and second availability signals V1 and V2 and / or the first and second non-availability signals NV1 and NV2 can also be generated via a user interface, in particular by operating personnel, when a door leaf 5a or 5b or both door leaves 5a and 5b of a door device 200 can or should not be operated.

[0074] If, for example, there is no fault in the second door leaf 5b, the second motor 1b, or in the drive train that mechanically connects the second door leaf 5b to the second motor 1b, the first electronic door control 10 generates, for example, a second availability signal V2 for the second door leaf 5b, which means that it can be operated without restriction.

[0075] The first electronic door control 10 therefore preferably monitors the vehicle door device 200 for defects and errors and, depending on this monitoring, evaluates the availability of its door leaves 5a, 5b with regard to permitted or prohibited operation. This monitoring, including the generation of the availability signals V1, V2 or the non-availability signals NV1, NV2 for the two door leaves 5a, 5b, as well as the control of the first and second drive devices 9a and 9b, are therefore encompassed by the first part of the functions of the door leaf operation or door leaf actuation control. Of course, it is also conceivable that a non-availability signal, namely the first and second non-availability signals NV1 and NV2, is generated by the first electronic door control 10 for each of the two door leaves 5a and 5b.

[0076] The first unavailability signal NV1 for the first door leaf 5a and / or the second unavailability signal NV2 for the second door leaf 5b can be generated by the first electronic door control 10 even if it is prompted to do so, for example by means of a user interface not shown here, for example by an input from the train driver or maintenance personnel via the user interface, that an actuation of, for example, the first door leaf 5a is not desired because, for example, it has been determined that actuation of the first door leaf 5a represents a risk due to damage to the first door leaf 5a.

[0077] The first electronic door control 10 is therefore designed such that the actuation signals S1, S2 for the door leaves 5a, 5b, transmitted by the second electronic door controls 56 and generated by actuating the actuating elements 52, 52b of the actuating device 51, can only be converted into an activation of the motor 1a, 1b of the respective door leaf 5a, 5b if an availability signal V1 or V2 has been generated for the respective door leaf 5a, 5b and no non-availability signal NV1 or NV2 has been generated. The actuation signals S1, S2 represent instruction signals, generated in particular by the second electronic door control 56, for the first electronic door control 10 with regard to an activation of the first and second drive devices 91 and 9b, in particular the first and second motors 1a, 1b.

[0078] In the example discussed here, where the first electronic door control 10 generates a non-availability signal NV1 for the first door leaf 5a, but an availability signal V2 for the second door leaf 5b, these signals are each fed into the second electronic door controls 56 via the second data bus 57 and processed there.

[0079] If the first electronic door control 10 has then generated a non-availability signal NV1 for the first door leaf 5a, for example, the first actuation signal S1 generated by a possible actuation of the first actuating element 52a of the actuating device 51 and transmitted via the second data bus 57 for an actuation of the first door leaf 5a or for the first motor 1a in the first electronic door control 10 is overwritten or rendered ineffective, so that the first door leaf 5a cannot then be actuated.

[0080] On the other hand, if the first electronic door control 10 has generated an availability signal V2 for the second door leaf 5b, for example, a second actuation signal S2 for an actuation of the second door leaf 5b generated by a possible actuation of the first actuating element 52a of the actuating device 51 of the second door leaf 5b is not overwritten in the first electronic door control 10, so that the second motor 1b or the second door leaf 5b can then be actuated.

[0081] The evaluation of the availability or non-availability signals V1, V2 and NV1, NV2, respectively, fed from the first electronic door control 10 into the second electronic door control 56 are therefore included in a second part of the functions of the door leaf operation or door leaf actuation control, which the second electronic door control 56 provides, in order to visually and / or acoustically display the availability or non-availability of the door leaves 5a, 5b via the availability display devices 50. Depending on this evaluation, the availability display devices 50 integrated in the door leaves 5a, 5b or their display devices 54 are therefore controlled.

[0082] Fig. 3 shows a schematic individual representation of the playback device 54 of Fig. 2 according to a preferred embodiment. The playback device 54, which is arranged in particular on each door leaf 5a, 5b, generates

[0083] - on the first door leaf 5a, first optical information depending on the first availability signal V1 about the availability of the first door leaf 5a or depending on the first non-availability signal NV1 about the non-availability of the first door leaf 5a, and

[0084] - on the second door leaf 5b, second optical information depending on the second availability signal V2 about the availability of the second door leaf 5b or depending on the second non-availability signal NV2 about the non-availability of the second door leaf 5b.

[0085] The first and second optical information here consists, for example, of LEDs illuminating in the colors "green" and "red," with an availability signal V1 or V2 for a door leaf 5a, 5b being assigned the color "green," for example, and an unavailability signal NV1 or NV2 for a door leaf 5a, 5b being assigned the color "red," for example. This assignment is easily understandable for passengers.

[0086] The display device 54 is therefore designed here as an optical display device and has a light source field, here in the form of a light source ring 55, which is vertically divided into a first light source ring part 56a for the first door leaf 5a and a second light source ring part 56b for the second door leaf 5b and here, for example, encloses the actuating device 51. The first and second light source ring parts 56a and 56b are each formed here, for example, by an LED strip, which can then be controlled by the controller with regard to the color of the emitted light.

[0087] If we now assume the case described above, in which the rail vehicle is stationary at a stop or in a station, and therefore a general release signal for the door leaves 5a, 5b has been generated and received by the first electronic door control 10, the latter assigns a first unavailability signal NV1 to the first door leaf 5a and a second availability signal V2 to the second door leaf 5b. The first electronic door control 10 then feeds the first unavailability signal NV1 into the second electronic door control 56 of the first door leaf 5a and the second availability signal V2 into the second electronic door control 56 of the second door leaf 5b. There, these signals are interpreted or evaluated, and depending on these signals, the respective illuminant ring parts 56a, 56b of the arranged therein

[0088] Playback devices 54 are controlled.

[0089] For example, the second electronic door control 56 of the first door leaf 5a controls the first and second light ring parts 56a, 56b arranged there to emit red light. Conversely, the second electronic door control 56 of the second door leaf 5b controls the first and second light ring parts 56a, 56b to emit green light. The color logic then informs the passenger at the stop or in the station, or inside the rail vehicle, that the first door leaf 5a is locked and only the second door leaf 5b can be operated for boarding or disembarking.

[0090] However, if the rail vehicle has started moving and left the stop or station, the general release signal for the door leaves 5a, 5b is not generated or is suppressed, so that the first electronic door control 10 then assigns a first unavailability signal NV1 to the first door leaf 5a and a second unavailability signal NV2 to the second door leaf 5b. The second electronic door control 56, to which the unavailability signals NV1 and NV2 have been transmitted, then controls the first and second illuminant ring parts 56a, 56b of both display devices 54 to emit red light.

[0091] Fig. 3 and Fig. 4 now show the two-leaf vehicle door device 200 of Fig. 2 with an extension of the availability display devices 50 of the door leaves 5a, 5b. The availability display devices 50 are in turn each controlled by the second electronic door control 56 shown in Fig. 2. In addition, although not explicitly shown, actuating devices 51 are provided for both door leaves 5a and 5b. As in Fig. 2, the first door leaf 5a is provided with a first window 110a and the second door leaf 5b with a second window 110b.

[0092] In automatic door leaves for rail vehicles, a finger guard rubber on the closing edge serves to prevent injuries. According to this exemplary embodiment, an optical display device, e.g., an LED strip, is integrated into or on this finger guard rubber, which can visually indicate the availability or unavailability of the respective door leaf 5a, 5b with regard to possible operation.

[0093] Therefore, for example, an illuminable finger protection device 120a, 120b is arranged on each of the closing edges 7a, 7b of the door leaves 5a, 5b: a first finger protection device 120a on the first door leaf 5a and a second finger protection device 120b on the second door leaf 5b. The first illuminable finger protection device 120a comprises a first finger protection strip (not explicitly shown here) and a first illuminating means 150a, and the second illuminable finger protection device 120b comprises a second finger protection strip (not explicitly shown here) and a second illuminating means 150b. The protection strips can be made of an opaque or a fully or partially translucent plastic material, which can also be designed to be reversibly deformable. The illuminating means 150a, 150b can each be designed, for example, as rod-shaped LED arrangements. In the case shown in Fig.In the embodiment shown in Fig. 4, the lighting means 150a, 150b preferably each extend over an entire length of the closing edges 7a, 7b of the two door leaves 5a, 5b.

[0094] The lighting means 150a, 150b can be connected to the protective strips in different ways. If the protective strip is opaque, for example, the lighting means 150a, 150b can be applied to the protective strip by adhesive or other types of connection. The lighting means 150a, 150b can also be arranged in a groove in the protective strip. If the protective strip is at least partially translucent, the lighting means 150a, 150b can be arranged, for example, in a groove or a cavity in a translucent region of the protective strip. The lighting means 150a, 150b is activated or deactivated, for example, by the second electronic door control 56 depending on the availability signal V1 or V2 or the non-availability signal NV1 or NV2 input by the first electronic door control 10.If the light source 150a, 150b is activated, it illuminates (in particular, with a specific color), which may indicate that the door leaf 5a or 5b associated with the respective light source 150a or 150b is available for operation. If, however, the light source 150a, 150b is deactivated, it does not illuminate, which may indicate, for example, that the door leaf 5a or 5b associated with the respective light source 150a or 150b is not available for operation.

[0095] Also, as in the present case, the availability and unavailability of the door leaves 5a, 5b can be indicated by different colors. Through appropriate control by the second electronic door control units 56 integrated into the door leaves 5a, 5b, the availability or unavailability of the door leaves 5a, 5b can be indicated by means of the lighting devices 150a, 150b.

[0096] If the first door leaf 100a is not available for operation, for example, the first light source 150a is controlled by the associated second electronic door control 56 in the first door leaf 5a so that it illuminates red, for example, to signal that the first door leaf 5a cannot be operated. If the second door leaf 5b is to be available for operation, the second light source 150b is controlled by the associated second electronic door control 56 in the second door leaf 5b so that it illuminates green, for example, to signal that the second door leaf 5b can be operated.

[0097] An alternative or additional possibility for indicating the availability or non-availability of the respective door leaf 5a, 5b with regard to possible actuation by means of a visual display device can be implemented by displays 130a, 130b, a first display 130a and a second display 130b. The first display 130a can be arranged or integrated, for example, in or on the first window 110a of the first door leaf 5a, and the second display 130b can be arranged or integrated, for example, in or on the second window 110b of the second door leaf 5b. The displays 130a, 130b can, in particular, be transparent OLED displays.

[0098] The availability or non-availability of the respective door leaf 5a, 5b or both door leaves 100a, 100b can then be displayed on the displays 130a, 130b, particularly using alphanumeric characters. For example, availability can be visually indicated by the message "Door in operation," while non-availability can be visually indicated by the message "Door locked," so that the passenger is informed which of the two door leaves 5a or 5b they can operate.

[0099] The availability or unavailability of a door leaf 5a, 5b can also be communicated to a passenger by acoustic information, such as spoken announcements ("left door leaf defective"), reproduced by an acoustic reproduction device such as a sound module 58. This sound module 58 is then in turn controlled by the second electronic door control 56 depending on the availability signal V1, V2 or the unavailability signal NV1, NV2 input by the first electronic door control 10, as shown in Fig. 2.

[0100] As the example described above shows, a first part of the functions of the door leaf operation or actuation control of the two door leaves outside the door leaves 5a, 5b is provided by the first electronic door control, while a second part of the functions of the door leaf operation or actuation control of the door leaves 5a, 5b is provided by the second electronic door control 56 arranged in or on the door leaves 5a and 5b, respectively. Accordingly, the second part of the functions of the door leaf operation or actuation control can be performed by a second electronic door control 56 independently of the first electronic door control 10, such as, for example, the local control of the availability display device 50.

[0101] However, this division of the functions of the door leaf operation or door leaf actuation control is not limited to the applications described above, but can be extended to other functions.

[0102] For example, the second door control 56 can comprise a contactless control or regulation of the door leaves 5a, 5b, wherein the second part of the functions of the door leaf operation or door leaf actuation control involves generating instruction signals S1 for the door leaf drives or motors 1a, 1b depending on a signal from a contactless proximity sensor arranged on or in at least one door leaf 5a, 5b, which is generated depending on a relative distance between a person and / or an object and the at least one proximity sensor. This realizes an automatic opening of the door leaves 5a, 5b, controlled by the second door control 56, when a person or an object approaches the proximity sensor integrated in at least one door leaf 5a, 5b.The second part of the functions of the door leaf operation or door leaf actuation control then comprises an evaluation and processing of the signal of the contactless proximity sensor as well as a generation of the instruction signal S1 to the first electronic door control 10 depending thereon, for example to activate or deactivate the first and / or second drive device 9a, 9b and thereby automatically control the two door leaves 5a, 5b depending on the proximity.

[0103] The second door control 56 can also include a control for anti-pinch prevention or pinch or collision detection, wherein the second part of the functions of the door leaf operation or door leaf actuation control comprises generating a detection signal representing a pinch or collision situation depending on a signal from at least one pinch or collision detection sensor, which is installed, for example, on at least one of the two door leaves 5a, 5b. The second part of the functions of the door leaf operation or door leaf actuation control then comprises evaluating and processing the signal from the pinch or collision detection sensor and generating the instruction signal S1 to the first electronic door control 10 depending thereon, for example, to deactivate the first and / or second drive device 9a, 9b and thereby eliminate the pinch or collision situation.
