Description

The invention relates to an emergency system and a method for making an emergency call in a passenger transport vehicle having at least one passenger compartment, and to a passenger transport vehicle.The useful value of a highly automated vehicle for transporting persons results from the replacement of the human bus driver by a technical system. For cost and capacity reasons, there is no need for a permanent register located in the vehicle, which can perform tasks such as, for example, inlet control, answering smaller requests for travel, descaled conflicts, or else intervention in hand-held manipulations. Furthermore, a quenching effect, generation function in the case of penalty records, etc. are therefore also dispensed with.This leads to highly automated road traffic for (public) transportation of people being accustomed to a considerable safety risk and inherent possibility of crimilitity. This extends far beyond aspects of functional security, behavior security and information security (cyber security).Autonomous vehicles are therefore increasingly equipped with so-called emergency call systems. Depending on the configuration, such emergency call systems offer the possibility of sending manually triggered emergency calls and / or automatically upon the occurrence of a specific event. Normally, in the case of an automated emergency call (e-call), a set of data is transmitted once at the beginning of the emergency call and subsequently switched to the voice mode, in which the emergency call is then terminated.For example, there are emergency call systems specifically designed for ride sharing to increase the safety of drivers and passengers, where the emergency call systems include a camera and cloud connection as well as a wireless SOS button through which assistance may be requested.DE 10 2020 201 629 A1 discloses an emergency call system for a vehicle, comprising a transmitting and receiving unit which is designed to connect the emergency call system to an emergency call centre, a microphone device, a loudspeaker device and a control and computing unit, coupled to the aforementioned components, with an execution program for the emergency call system, wherein at least one sub-region of the execution program can be switched on and / or off and set in a user-defined manner by means of at least one received signal from the emergency call centre.An improved emergency call system for automated passenger transport vehicles is therefore desirable.It is an object to specify an improved emergency system, especially for passenger transport such as buses or trains, and to this end an improved passenger transport vehicle.The object is achieved by an emergency system having the features of claim 1 and a passenger transport vehicle having the features of claim 14 and a method having the features of claim 19.Advantageous embodiments are evident from the dependent patent claims, the description and from the figures.The object is achieved by an emergency system for placing an emergency call in a passenger transport vehicle having at least one passenger compartment, wherein an interaction terminal is provided, wherein the interaction terminal comprises different modes and is designed for selecting the different modes and for manually inputting information in the respective selected modes, wherein the different modes comprise at least one emergency mode, and wherein an emergency operating unit is provided which is arranged in the passenger compartment, wherein the emergency operating unit is coupled to the interaction terminal, and wherein the emergency operating unit is designed to bring about an activation of the interaction terminal upon manual actuation, wherein the interaction terminal is designed to put into the emergency mode upon activation by the emergency operating unit or is designed to put into the emergency mode upon manual activation of the emergency mode, and to place an emergency call message to a predefined emergency call center and also to establish a bidirectional connection to a service center, for the input of information by the vehicle occupant for forwarding to the service center and / or for establishing an interaction between the vehicle occupant and the service center.The service center and the emergency call center can be identical, for example the police.Various other modes may include, besides the emergency mode for releasing or retrieving assistance, for example, inquiring about satisfaction of travel or state of the passenger transport vehicle, entertainment, etc. Other modes may also be provided.In this case, the emergency call message or the connection can be established, for example, by radio.An interaction terminal can have, for example, a monitor as a touchscreen, a camera for recording the vehicle occupant, a microphone, a loudspeaker and, for example, optionally operating keys for manual input, and also fastening elements, a housing and, for example, a visual protection, for example a polarization filter. By way of the visual protection, for example, only the direct user can see the inputs.Furthermore, the interaction terminal has, for example, connections to a vehicle control device in the passenger transport vehicle, for transmitting and executing commands to and through the vehicle control device and, for example, for setting up and carrying out the bidirectional connection to the service center / emergency call center through a corresponding interface / antenna system / mobile radio network as communication interface to the smartphone.The interaction terminal for inputting an emergency call / message can be a component of a larger protection system.According to the invention, the emergency control unit is coupled to the interaction terminal, i.e. connected to the latter for the data transmission. This can be a cable connection or radio connection.The emergency control unit is designed, for example, as a button / emergency button, which is arranged in a housing and must be pressed for triggering.According to the invention, when the emergency control unit is manually operated, the interaction terminal is activated and automatically placed in the emergency mode.Furthermore, the interaction terminal can be automatically placed in the emergency mode by its own activation.In this case, the interaction terminal module is designed to issue an emergency call message to an emergency call center in the emergency mode and to contact a predefined service center.Furthermore, according to the invention, a bidirectional connection to a service station is established for the input of information by the vehicle occupant for forwarding to the service station. These can be input, for example, by means of manual input (touchscreen), so that, for example, pre-selected threat positions can be displayed for selection.An interaction can also be produced between the vehicle occupant and the deployment site. This can take place, for example, as an acoustic interaction, via microphone and loudspeaker and camera.As a result, the vehicle occupants of the passenger transport vehicle are authorized to send an emergency call to the emergency call center or a message to the operator / deployment point, in dependence on the risk of threat and the expected severity or the subjective feeling of safety, as well as to add further information to the emergency call.The emergency system according to the invention can provide more rapid information about the expected severity and the type of emergency by the possibility of differentiating the emergency call, such as, for example, accident, myocardial infarction, threat by attackers, fire, etc. A further differentiation of the emergency call can be, for example, in the case of a threat situation: attackers with knives, a plurality of attackers, etc., so that the responsible emergency call center / service station is already extensively informed beforehand about the severity and the type of emergency, so that immediate targeted intervention is made possible.Thus, the emergency system according to the invention enables, for example, the interrogation of the 5-W questions (what, how, where) in order to enable an adequate response, for example by the police, fire fight, by the response.Such an interactive emergency system according to the invention has a strong frucation factor for perpetrators and serves as a safeguard for vulcanizable vehicle occupants.Due to the dual possibility of placing an emergency call, namely by the emergency control unit and the interaction terminal, and the automated placing of an interaction terminal in the emergency mode with the possibility of setting up a, for example, speech and pictorial interaction between the vehicle occupant and the service center, or due to the possibility of inputting into the, for example, touchscreen, older or more recent, non-technically trained, vehicle occupants also have the possibility of rapidly placing an emergency call.By means of the emergency system according to the invention, specific threat scenarios can be categorized first, for example after the most severe damage to be assumed. In this case, the damage can be categorized as financial damage, damage to the well-being of the person, damage to the person (psychic or without injury to the body), damage to the person-body injury easily, etc.For emergency situations, the vehicle occupants are quickly authorized to send an emergency call to the emergency call center or a message to the operator / emergency site on the basis of the emergency risk and the expected severity or the subjective safety sensation.The emergency system according to the invention allows differentiation of the message.In a further embodiment, the interaction terminal is designed to activate a microphone and a loudspeaker and a camera in an emergency mode for image transmission and for acoustic input of the information and / or acoustic interaction between the vehicle occupant and the deployment site. As a result, a videocall, for example, can be activated with an operator of the place of use even in emergency mode. This can have a deterring effect on an attacker or serve for safety / quieting the vehicle occupants, for example in the event of an accident in the vehicle. An application of automated speech recognition may also be possible in the acoustic interaction.In a further embodiment, the interaction terminal is designed to activate an existing interior sensor system, wherein the interior sensor system comprises at least one interior camera, but preferably a plurality of cameras, for pictorially capturing the passenger compartment as interior data, wherein the interaction terminal is designed to effect permanent storage of at least the interior data recorded during the activated emergency mode. In this case, for example, a general storage in a ring memory can be provided, the data of which are transmitted and stored in a permanent memory in the emergency mode in order to secure the latter. In addition to cameras, interior sensors can also have microphones for capturing the acoustics, for example.In a further embodiment, the interaction terminal is designed to query whether a threat situation is present and, if a threat situation is present, to query what type of threat is present and / or to query the perceived strength of the threat. The query can be formed, for example, by selecting predefined threat situations and selecting the applicable ones, or an acoustic query. Threat situations may be theft, physical threat, etc.Furthermore, the interaction terminal can be designed to contact a corresponding emergency location and / or emergency call center depending on the strength input and / or the type of threat situation.Furthermore, external sensors may also be present, for example lidar / radar sensors / cameras for recording the external space as external space data. This exterior space data can likewise be transmitted from the ring memory into the permanent memory in the emergency mode, for example.For this purpose, the interaction terminal can provide a trigger signal to a data recorder, for example, for the permanent storage of previously recorded data which were temporarily stored in the ring memory, and for the recording of all subsequent relevant monitoring data and for the storage of these in the permanent memory.In this case, these stored data can serve, for example, as evidence for law enforcement or civil-law measures, etc.In a further embodiment, the interaction terminal is designed to transmit the interior data recorded during the activated emergency mode to an external server. The acquired data, for example interior data and exterior data, can be combined, for example, with records from the ring memory to form data packets. The data packets can then be uploaded to an external server, for example a cloud. Subsequently, for example, identifiers specific to the data packet can be generated and assigned to the data packet.On the basis of the identifiers, for example, affected vehicle occupants and / or else the emergency / emergency call center can authenticate themselves and access the data packet via the identifier and then use this data packet, for example as evidence.Furthermore, the interaction terminal can be designed to transmit the interior data recorded during the activated emergency mode at least to the service station. The exterior data can likewise be transmitted. These can likewise be transmitted to the service station. This allows a more rapid assistance since the emergency situation of the service site is already known in advance. Thus, for example, in the event of a severe accident, a plurality of hospital cars or else already a rescue helicopter can be sent out or else the technical auxiliary work can be informed.In a further embodiment, the interaction terminal is designed to transmit further messages to the emergency call center and / or the service center, wherein the further messages can be selected from the following group: adding the current location or a respectively updated location, adding the vehicle route still to be managed, adding an ID (vehicle ID identification number) of the passenger transport vehicle, adding a current seat number relating to the interaction terminal.The vehicle or the seat has, for example, an identification number which is displayed to the vehicle occupant or is attached in front of the seat thereof or at the interaction terminal.In the case of an emergency call, the vehicle occupant of the emergency / emergency call center can pass through the ID in order to establish the bidirectional connection.The ID can also be seat-specific, so that the emergency / emergency call center can immediately determine the position of the vehicle occupant in the passenger transport vehicle. If the seat is likewise transmitted in the ID, a marking can be placed via the live stream, which marking shows the seat / position of the vehicle occupant within the image to the emergency call center / place of use.In particular, in a further embodiment, the emergency control unit can be designed to issue a separate emergency call to the emergency call center if a connection to the interaction terminal cannot be established. If, for example, the emergency control unit signals that no connection to the interaction terminal can be established, then this can place a separate emergency call to a predefined emergency call center, for example the police. At least data of the passenger transport vehicle can be added to determine where the emergency call comes. As a result, an emergency call can be transmitted in a secured manner even in the event of a fault in the connection to the interaction terminal or a fault in the interaction terminal itself.Furthermore, the emergency control unit can be designed as a multi-emergency button and can have a plurality of input keys for different types of incidents.In this case, the plurality of input keys may reflect a threat level which is transmitted with the emergency call, depending on the threat sensation. It can also be designed for different types of emergency calls to different emergency call centers, for example police or fire fights in the event of a fire of the passenger transport vehicle, etc.In a further embodiment, the interaction terminal is designed to display a plurality of predefined emergency situations for selection and / or to display different locations of use for selection in the emergency mode.For example, such emergency situations can be: accident, fire, attacker / threat by persons, illness, for example, when a vehicle occupant suffers a myocardial infarction.Furthermore, for example, the interaction terminal can be designed to establish a connection to the correspondingly stored place of use at least as places of use, the fire weir, hospital, wherein doctor / rescue provider / hospital cart are also included here or police is displayed for selection, and if manually selected accordingly. As a result, for example, a rapid and pictorial first differentiation of the emergency situation can be achieved and, for example, first assistance can be provided by the vehicle occupants in the event of a myocardial infarction.In a further embodiment, the interaction terminal can be designed to establish a connection to a predefined stored place of use in the event of no selection of an emergency situation or place of use. An emergency call can also be made. In this case, the time interval from the selection to the automatic connection can be selected to be very short, for example, so that only little valuable time is lost.Furthermore, the interaction terminal can be designed to establish a connection to a mobile terminal, for example a smartphone, tablet, or smart watch of the vehicle occupant in the emergency mode.In this case, the connection to the mobile terminal can be established via a vehicle ID, QR code entered in advance into the mobile terminal and / or automatically via NFC (Near Field Communication).In addition, an emergency call / message can also be supported via the smartphone of the vehicle occupant, for example, so that locating the vehicle, locating the vehicle occupant in the vehicle, and estimating the situation is easier. In this case, a connection between the vehicle and the smartphone can be established via a QR code or automatically via, for example, NearFieldCommun via Bluetooth or via the input vehicle ID.The vehicle ID identification number is that number which is displayed to a vehicle occupant, for example, when boarding or is mounted in the passenger transport vehicle, for example, at the seat locations.The vehicle ID identification number can be, for example, the license plate of the passenger transport vehicle in a simplified manner. In the case of an emergency call, the vehicle occupant of the emergency station can pass through the ID or this is transmitted in an automated manner. The interaction terminal can then be activated, for example, in order to start a video recording with the place of use.The service center can thus establish a communication interface to the vehicle, for example, on the basis of the ID for identification.In addition, further information which is present about the vehicle, the interior sensor system, the smartphone of the vehicle occupant, etc., can also be included by the activating emergency system in the event of an emergency call.Likewise, in such a case, the personal emergency data stored on the mobile terminal, such as anamnesis infos, such as previous disorders, blood group, possible obstructions, etc., as well as emergency contacts, can be transmitted via the interaction terminal to the place of use. Thus, for example, first responders can be informed directly beforehand about the blood group in the case of persons who are in an accident or other diseases, etc.Conversely, when the interaction terminal is activated, the mobile terminal can transmit information regarding emergency contacts and first responder information.The smartphone can thus be used for emergency call and this can be supported via the interaction terminal, for example by a videocall with the point of use.The object is furthermore achieved by a passenger transport vehicle having at least one passenger compartment comprising an emergency system as described above or a plurality of emergency systems each having an interaction terminal.Furthermore, in a further embodiment, each emergency system or the passenger transport vehicle is assigned a vehicle ID (identification number), wherein the interaction terminal is configured to add the vehicle ID (identification number) to an emergency call message and / or the vehicle ID (identification number) to the information to a service station.In particular, such a passenger transport vehicle can be an autonomously driving bus / train or taxi.In a further embodiment, the passenger transport vehicle has an interior sensor system, wherein the interior sensor system is designed for the continuous generation of interior data for the continuous interior monitoring of the passenger compartment, wherein the passenger transport vehicle is designed to identify a threat situation on the basis of the continuous interior monitoring and to activate the at least one emergency system and to transmit at least the interior data to a predefined place of use.The interior sensor system can be designed primarily as cameras. The passenger transport vehicle or an evaluation unit recognizes possible threats by continuously monitoring the interior and, if applicable, the exterior. If a vehicle occupant is prevented from placing an emergency call, for example, the emergency system itself can thus be activated. This increases safety. In addition, in the case of an emergency call, the most likely threat cases can first be displayed on the interaction terminal for selection.In this case, the passenger transport vehicle can have an evaluation unit which is designed to detect a threat situation in the interior data on the basis of artificial intelligence. This can be, for example, an artificial trained neural network or a convolutional network for evaluating image data.The object is furthermore achieved by a method for placing an emergency call in a passenger transport vehicle having at least one passenger compartment by an emergency system comprising the steps:providing an interaction terminal, wherein the interaction terminal comprises different modes and is configured for selecting the different modes and for manually inputting information in the respective selected mode, wherein the different modes comprise at least one emergency mode,providing an emergency operating unit which is arranged in the passenger compartment, wherein the emergency operating unit is coupled to the interaction terminal, and wherein the emergency operating unit carries out an activation of the interaction terminal upon manual actuation, wherein the interaction terminal is placed in the emergency mode upon activation by the emergency operating unit or is placed in the emergency mode upon manual activation of the emergency mode, and an emergency call message is transmitted to a predefined emergency call center and also establishes a bidirectional connection to a service location, for the input of information by the vehicle occupant for forwarding to the service location and / or for establishing an interaction between the vehicle occupant and the service location.Furthermore, as a further step, the interaction terminal can query whether a threat situation is present and, if a threat situation is present, query what type of threat is present and / or query the perceived strength of the threat and contact a corresponding emergency station and or emergency call center depending on the input strength and / or the type of threat situation.Further characteristics and advantages of the present invention will become apparent from the following description with reference to the attached figures. The following are shown schematically in the drawing: FIG. 1 shows an emergency system schematically, FIG. 2 shows a schematic of a multi-emergency button, FIG. 3 shows schematically an interaction terminal, FIG. 4 : a passenger transport vehicle, FIG. 5 : different vehicles ID (identification number) in the passenger transport vehicle FIG. 6 : Starting a video call in the event of a threat. FIG. 7 : shows the method on the basis of a threat situation.FIG. 1 schematically shows an emergency system 1 for making an emergency call in a passenger transport vehicle 5 having at least one passenger compartment.The emergency system 1 has, on the one hand, an emergency operating unit which is arranged in the passenger compartment. This can be designed as a multi-emergency button 2 a, 2 band can have a plurality of input buttons 13 for different types of emergency calls.In this case, the multi-emergency button 2 a, 2 bincludes a connection via cable or radio to an interaction terminal 3 for making an emergency call and also a communication interface 14 for directly making an emergency call to a predetermined emergency call center 7, such as police, fire fight, if the connection to the interaction terminal 3 cannot be established.In this case, the multi-emergency button 2 a, 2 bmay be arranged in a housing with a fastening element.Furthermore, the multi-emergency button 2 a, 2 bmay have different input keys 13.Fig. 2 shows a multi-emergency button 2a, 2b in detail.In this case, the multi-emergency button 2 acan have a plurality of input keys 13 in order to transmit a threat level with the emergency call depending on the threat sensation. The input keys 13 can each reflect a different degree of threat.Alternatively or additionally, the multi-emergency button 2 bhas further input buttons 13 which reflect various incidents such as medical emergency, accident, fire or other threats and which, when actuated, respectively establish a connection to a respective other emergency call center, such as police, fire fight, hospital / rescue agencies etc.The multi-emergency button 2 a, 2 bmay also be designed to input further information on different buttons upon request, similar to a machine query on the call: Press the orange button if further persons are in danger.Furthermore, the interaction terminal 3 is provided, FIG. 3 : this comprises a monitor as a touchscreen 15, a camera 16 for recording the vehicle occupant, a microphone 17, a loudspeaker 20 and, for example, optionally buttons for manual input, fastening elements, a housing and, for example, a visual protection, such as, for example, a polarization filter. By way of the visual protection, for example, only the direct user can see the inputs. Furthermore, operating keys 18 can be provided.Furthermore, the interaction terminal 3 has a connection to a vehicle control device 4 in the passenger transport vehicle 5, for transmitting and executing commands to and through the vehicle control device 4 via a communication interface 14, for example for setting up and carrying out a bidirectional connection to a service station 6 or emergency call center through a corresponding communication interface / antenna system / mobile radio network 19.Furthermore, the interaction terminal 3 has different modes 21 and is designed to select the different modes 21. Such modes 21 can serve, for example, without being connected to a service station 6 merely for information purposes. In this case, for example, a mode 21: vehicle state, satisfaction, entertainment etc. can be present in order to input the various messages without an emergency call center 7 or emergency station 6. In this case, the messages can be input, for example, by means of the touchscreen of the interaction terminal 3. Such messages may include, for example, vehicle position, vehicle condition (Drunk, Clean), planned route, or other traffic information.Further, the interaction terminal 3 has an emergency mode. This can be activated directly, for example by selecting on the touchscreen or by actuating the multi-emergency button 2 a, 2 b.When activated, the interaction terminal 3 enters the emergency mode and sends an emergency call message to a predefined emergency call center and establishes a bidirectional connection to the emergency site 6, for the input of information by the vehicle occupant for forwarding to the emergency site 6 and / or for establishing an interaction between the vehicle occupant and the emergency site 6.In this case, the interaction terminal 3 can transmit further messages to the emergency call center 7 and / or to the service center 6, wherein the further information is, for example: adding the current location or a respectively updated location, adding the vehicle route still to be managed, adding an identifier of the passenger transport vehicle 5, adding a current seat number relating to the interaction terminal 3, the vehicle state, traffic information, vehicle occupant information, etc.If the interaction terminal 3 is activated, it can establish a connection to an operator as the place of use 6. In this case, the microphone 17 and the loudspeaker 20 as well as the camera 16 are activated for image transmission and for setting up a video call and for acoustic input of the information and / or acoustic interaction between the vehicle occupant and the place of use 6.Thus, the emergency system according to the invention enables, for example, the interrogation of the 5-W questions (which, how, who, are, are waiting) by the operator / service station 6 in order to enable an adequate reaction, for example by the service station 6 or the emergency call centre 7, by the answering.The interaction can thus have a deterring effect on an attacker, for example, or serve for safety of the vehicle occupants, for example in the event of an accident in the passenger transport vehicle 5. The interaction terminal 3 can also be designed to recognize / estimate its origin and possible languages on the speech, accounting, skin colour, etc. of the vehicle occupant.These languages can be proposed by the interaction terminal 3 to the vehicle occupant in addition to the most likely.Alternatively or additionally, in addition to acoustic input by videocall, it is also possible to query by display and input into the touchscreen 15.If the interaction terminal 3 is activated, it in turn activates an existing interior sensor system 8 and exterior sensor system, provided that it was not activated in advance.The interior sensor system 8 and exterior sensor system here comprise at least one interior camera or a plurality of cameras for pictorially capturing the passenger compartment as interior data and the exterior compartment as exterior data.In this case, the interaction terminal 3 causes at least permanent storage of the interior / exterior data recorded during the activated emergency mode to be effected during the activated emergency mode.For this purpose, the interaction terminal 3 can transmit a trigger signal to a data recorder 10 (permanent memory), for storing previously recorded data which were temporarily stored in a ring memory, for example, and for recording all subsequent relevant monitoring data and for storing these in the permanent memory.In the case of each emergency call / message, these stored data can finally serve as evidence for, for example, law enforcement or civil-law measures.The interior data and exterior data recorded in this way can also be transmitted to the service station 6, as a result of which the service station can better estimate the emergency.The interaction terminal 3 can also carry out a transmission of the stored exterior space data and interior space data or else at least interior space data recorded during the activated emergency mode to an external server. The acquired interior data and exterior data can be combined, for example, with records from the ring memory to form data packets.The data packets can then be uploaded into the external server, for example a cloud 9. Subsequently, for example, a specific identifier for the data packet can be generated and assigned to the data packet.By means of the identifier, for example, affected vehicle occupants and / or else the emergency station 6 / emergency call center 7 can authenticate themselves and access the data packet via the identifier and then use this data packet, for example as evidence.Also, in the emergency mode, the interaction terminal 3 can display a plurality of predefined emergency situations for selection and / or display different locations 6 for selection.For example, such emergency situations can be: accident, fire, attacker / threat by persons, illness, for example, when a vehicle occupant suffers a myocardial infarction.In this case, for example, the service stations 6, the fire weir, hospital / doctor or police can be displayed for selection, and, if manually selected accordingly, a connection to the correspondingly stored service station 6 can be established. As a result, for example, a rapid and pictorial first differentiation of the emergency situation can be achieved and first assistance can be provided.Furthermore, in the emergency mode, the interaction terminal 3 can set up a connection to a mobile terminal, for example a smartphone 11 of the vehicle occupant.In this case, the connection to the smartphone 11 can be established via a passenger transport vehicle 5 ID, QR code entered in advance into the smartphone 11 and / or automatically via NFC (Near Field Communication).The vehicle ID identification number is that number which is displayed to a vehicle occupant, for example, when boarding, or is mounted in the passenger transport vehicle 5, for example, at the seat locations.The vehicle ID identification number can be, for example, the license plate of the passenger transport vehicle 5 in a simplified manner. In the case of an emergency call, the vehicle occupant of the service center 6 can pass through the ID or this is transmitted in an automated manner. The interaction terminal can then be activated, for example, in order to start a video recording with the service station 6.The service center 6 can thus establish a communication interface to the passenger transport vehicle 5, for example on the basis of the ID for identification.In addition, an emergency call / message can also be supported via smartphone 11 of the vehicle occupant, for example, so that locating passenger transport vehicle 5, locating the vehicle occupant in passenger transport vehicle 5, and estimating the situation is easier.In addition, further information which is present about the passenger transport vehicle 5, the interior sensor system 8, the smartphone 11 of the vehicle occupant, etc., can also be included in the case of an emergency call.For example, in such a case, the personal emergency data 12 stored on the mobile terminal / smartphone 11, such as anamnesis infos, such as previous diseases, blood groups, possible disability, etc., as well as emergency contacts, can be transmitted via the interaction terminal to the emergency site 6. Thus, for example, first responders can be informed directly beforehand about the blood group in the case of persons who are in an accident or other diseases, etc.Furthermore, the smartphone 11 can be used for emergency call and this can be supported via the interaction terminal 3, for example with a videocall with the point of use 6.If there is thus a risk situation with respect to the vehicle occupant, then a threat message can be made by means of the emergency system 1 according to the invention via the multi-emergency button 2 a, 2 bor the interaction terminal 3 or the smartphone 11 coupled to the interaction terminal 3. When the emergency button 2a, 2b is actuated, an emergency call center 7 is directly informed. This activates the interaction terminal 3 for further input and starting a transmission to a service station 6. Furthermore, data storage of exterior data and interior data is made possible in the case of data recorders 10, the transmission of the stored data to a cloud 9 is ensured and at least the interior data is transmitted to the service station 6 in a secured manner.The vehicle occupant can differentiate the threat situation by means of an input via the interaction terminal 3 (videocall, touchscreen input) on the basis of the emergency system 1 according to the invention. The service center 6 can select suitable measures on this basis and forward them to the emergency call center 7.FIG. 4 schematically shows a passenger transport vehicle 5 having at least one passenger compartment comprising an emergency system 1 or a plurality of emergency systems 1 each having an interaction terminal 3. In particular, such a passenger transport vehicle 5 can be an autonomously driving bus / train or taxi.In this case, each emergency system 1 or the passenger transport vehicle 5 is assigned a vehicle ID (identification number). This may be, for example, the license plate of the passenger transport vehicle 5 and an additional number which indicates the seat or the arrangement of the emergency system 1 in the vehicle (FIG. 5 ).In this case, the interaction terminal 3 can add this vehicle ID (identification number) of an emergency call message and / or the vehicle ID (identification number) to the information at an emergency location 6, with the result that the passenger transport vehicle 5 can easily be identified.Furthermore, the passenger transport vehicle 5 has the interior sensor system 8 and exterior sensor system for the continuous generation of interior data and exterior data.In addition, an evaluation unit is provided which detects a threat situation. On the basis of the detected threat situation, the latter can inform a predefined deployment location 6 and switch on the interaction terminal or terminals 3 for starting, for example, a video call (FIG. 6 ).The evaluation unit thus recognizes possible threats by continuously monitoring interior and exterior space and recognizes whether someone is prevented from sending an emergency call. For quenching, the interaction terminal 3 can be switched on.Specific threat scenarios can be categorized first by the emergency system 1 according to the invention, for example after the most severe damage to be assumed. In this case, the damage can be categorized as financial damage, damage to the well-being of the person, damage to the person (psychic or without injury to the body), damage to the person-body injury easily, etc.With regard to emergency situations, the vehicle occupants are quickly authorized to send an emergency call to the emergency call center 7 or a message to the operator / service station 6 on the basis of the emergency risk and the expected severity or the subjective safety sensation.The emergency system 1 according to the invention allows differentiation of the emergency call.FIG. 7 shows the method according to the invention in a threat situation. In a first step S 1, the threat is input via the multi-emergency button 2 a, 2 bor the interaction terminal 3. It can also be entered whether a threat is present for another person. The other person can also be specified more precisely, for example on the basis of the seat.In a second step S 2, the threat situation is interrogated in detail. This can already take place with the assistance of an operator / service station 6 / emergency call center 7 or exclusively via the input into the touchscreen 15.
