Description

The invention relates to a method for optimizing first-aid measures in the environment of a vehicle, wherein the vehicle recognizes whether a first-aid measure is required in the environment of the vehicle.In addition, the invention relates to a vehicle having at least one evaluation device, having at least one loudspeaker and having at least one light source.A first-aid course has completed many persons participating in road traffic once in life for driver's license checking. The necessary manipulations are learned over the years. If a situation occurs in which others must be assisted by means of reanimation measures, uncertainty arises with regard to the correct execution. In the worst case, it is not helped to make something wrong from anxiety.In order to simplify the first-aid measures, different options are known in the prior art for providing assistance to a first-aid person so that first-aid measures can be carried out correctly as far as possible.US 2022 / 0293262 A1 describes, for example, a context-sensitive guidance system (CSG) for providing clinical interventions for a patient in a medical emergency. The system includes a CSG machine, patient interface devices configured to generate signals indicative of physiological data of the patient, and a display device configured to provide a CSG user interface, and medical device(s) configured to connect to the patient interface devices, the CSG machine, and the display device, receive the signals, generate the physiological data from the signals, and transmit the physiological data to the CSG engine and the display device, wherein the CSG engine is configured to receive and evaluate the physiological data, identify a clinical intervention, and transmit a clinical intervention-based output to the medical device(s) configured to / are, performing at least one operation in response to the transmitted output.DE 20 2009 003 971 U1 discloses a device for supporting first responders. The device is a releasable arrangement which allows entrainment. It is provided that the device outputs acoustic action instructions that first responders should support.However, such a mobile device must be stored in the vehicle and present in order to be able to use it in an emergency as well. In addition, it must be actively operated by a first responder who may be overproved in an emergency situation and under stress.The invention is therefore based on the object of specifying a method for optimizing first-aid measures in the environment of a vehicle and a vehicle in which a first responder can be supported in first-aid measures in such a way that the measures can be carried out correctly even in large stress situations.This object is achieved in the present invention by the features of the characterizing part of claim 1 first in that acoustic and / or visual measures are initiated by the vehicle, which aid a first responder in the first-aid measures.First-aid measures are to be understood in particular as measures which are necessary for the initial supply of an injured person. These include, in particular, reanimation experiments. The environment of the vehicle can be a predefined region, for example a radius, around the vehicle. Depending on whether and which sensor system is installed on the vehicle, the area can be correspondingly larger or smaller. In any case, it must be ensured that within the predefined range around the vehicle, a detection that first-aid measures are required can take place.The acoustic or visual measures can have different configurations. The visual measures are preferably assistance for the first responder, so that the latter can recognize how a first-aid measure is to be carried out. In the acoustic measures, acoustic signals, in particular voice announcements, can be played accordingly, explaining to the first responder how to carry out a first-aid measure. In this case, it can be provided that the speech of the speech announcement is carried out in the office speech of the country in which the vehicle is located at this point in time, since it is conceivable that a resident of the country as a first responder will help in a potential accident site. However, it is also conceivable for the speech of the speech announcement to be output in a speech previously defined by a user. This preselection could be carried out, for example, via an input device of the vehicle.A first advantage of the method according to the invention is that a first responder receives direct visual and / or acoustic assistance arrangements which can safely conduct him through the first assistance measures even in a stress situation.Further preferred embodiments of the invention result from the other features mentioned in the dependent claims.In a first embodiment of the method according to the invention, it is provided that the vehicle recognizes, by an indication of a first responder, whether a first-aid measure is required. The indication can be made visually, for example. It is conceivable that a sinking of the first responder or another gesture, for example the crossing of the arms over the head, leads to the vehicle recognizing that a first-aid measure is required. In addition, an intentional activation can also take place, for example by means of a switch, a button and / or a touch display of an infotainment system.In this case, in a further embodiment of the method according to the invention, it can additionally be provided that the first responder's indication is made acoustically inside or outside the vehicle, the acoustic indication being assigned by means of a speech recognition of the vehicle. The acoustic indication can be, for example, a signal word that is called out by a first responder. However, it is also conceivable that the speech and, for example, the pitch of persons in the area of the vehicle is recorded by an evaluation unit. Depending on which words are spoken or even called, this can be seen as an indication that an emergency is present and first aid measures are necessary.In a further embodiment of the invention, it is provided that the environment around the vehicle is at least partially illuminated by the vehicle if the brightness of the environment falls below a specific brightness limit value. In particular, it can be provided that in the event of darkness, the direct area around the vehicle is illuminated. The brightness limit value can be dependent, for example, on the sunrise or on the sunset. In this case, various lighting devices of the vehicle can be used for illumination. It is conceivable that the headlights are used. Likewise, bending lights, side lights in exterior mirrors, tail lights, backup lights and others may be used. Such illumination or illumination simultaneously serves as a signal effect for other road users who can additionally provide assistance.In a further particularly advantageous embodiment of the method according to the invention, it is provided that the vehicle determines whether the person who requires a first-aid measure is an adult person or an infant. The distinction is relevant, for example, for performing cardiac pressure massages. In an adult human, a greater pressure is required than in an infant. The ascertainment can be carried out by evaluating data from vehicle cameras, for example interior cameras, front cameras, side cameras and / or rear cameras.In order to provide the first responder with a suitable assistance for a possibly necessary cardiac massage, it is provided in a further embodiment of the method according to the invention that a clock for a reanimation is output as part of a first assistance measure by means of available loudspeakers of the vehicle and / or that a clock for a reanimation is output as part of a first assistance measure by means of available light sources of the vehicle. An output clock, both visual and acoustic, helps a first responder, for example, to maintain the correct frequency in the event of a cardiac pressure massage or to give him an indication of how often pressure should be exerted on the chest of an injured person in the minute. The predetermined cycle can serve as an orientation for the first responder, so that a correct execution of the first-aid measure can be achieved.According to the invention, it is provided that by means of at least one UltraIdeBand antenna of the vehicle, an impression depth necessary for a cardiac massage is measured within the scope of the first-aid measure. In this way, first-aid measures carried out can be checked. It can be correspondingly measured how deep, for example, the rib cage of an injured person is pressed in by the first responder. By comparing with reference values, it can then be checked, for example, whether the first-aid measure is carried out correctly or whether adaptations are necessary.In this case, in a particularly advantageous embodiment of the method according to the invention, provision can additionally be made for acoustic indications to be output by available loudspeakers of the vehicle, which contain assistance about the necessary impression depth. For this purpose, for example, voice announcements can be made by the loudspeakers, which output clear information to the first responder as to whether or not the first-aid measure is carried out correctly. Speech outputs which animate the first responder to exert a stronger or weaker pressure would be conceivable. If carried out correctly, this can also be confirmed accordingly by a voice announcement, so that the first responder knows that he is carrying out the actions carried out correctly.In a further advantageous embodiment of the method according to the invention, it is provided that a visual assistance for carrying out the first-aid measure is projected onto the ground in the environment of the vehicle by the vehicle. In this case, it can be provided, for example, that a matrix LED light of the vehicle projects a heart onto the ground. A light carpet is placed around this heart. When the chest is pressed in during a reanimation, the light carpet collapses into the heart. When the impression depth is sufficient, the entire light carpet falls in, and when the pressure is too weak, a part of the light carpet remains stationary. In addition, with the impression depth correct, a hook is displayed as an indication of the correct execution. In this way, the first responder is provided with an easily comprehensible and highly visible instruction as to how the first-aid measure is to be carried out.The aforementioned object is also achieved by a vehicle, having at least one evaluation device, having at least one loudspeaker and having at least one light source. It is provided that a method according to the invention can be carried out by the evaluation device. The above explanations with respect to the method according to the invention also apply accordingly to the vehicle according to the invention.Electronic or electrical devices and / or other relevant devices or components according to the embodiments of the present invention described herein may be implemented using any suitable hardware, firmware (e.g., an application specific integrated circuit), software, or a combination of software, firmware, and hardware. For example, the various components of these devices may be packaged on an integrated circuit (IC) or on separate IC chips. Moreover, the various components of these devices may be implemented on a flexible printed circuit foil, a tape carrier package (TCP), a printed circuit board (PCB), or on a single substrate. Moreover, the various components of these devices may be a process or thread that runs on one or more processors in one or more computing devices, executes computer program instructions, and interacts with other system components to perform the various functions described herein. The computer program instructions are stored in a memory that can be implemented in a computing device using standard memory, such as random access memory (RAM). The computer program instructions may also be stored in other non-transitory computer readable media, such as a CD-ROM, flash drive, or the like. One skilled in the art should also appreciate that the functionality of various computing devices may be combined or integrated into a single computing device or that the functionality of a particular computing device may be distributed to one or more other computing devices without departing from the scope of the exemplary embodiments of the present invention.The various embodiments of the invention mentioned in this application can be combined with one another with advantage unless stated otherwise in the individual case.The invention is explained below in exemplary embodiments with reference to the associated drawings. The following are shown: FIG. 1 shows a schematic illustration of a vehicle, by means of which a method for optimizing first-aid measures in the environment of the vehicle is carried out, and FIG. 2 shows a schematic block diagram of various steps of a method for optimizing first-aid measures according to FIG. 1.FIG. 1 shows a vehicle 10, wherein the vehicle 10 detects whether a first-aid measure is required in the environment of the vehicle. Both acoustic and visual measures are initiated by the vehicle 10 to assist a first responder 12 in the first aid measures. The first-aid measures are actions that are necessary for first supplying an injured person 14. These include, in particular, reanimation experiments. By means of a predefined region around the radius 16, the environment of the vehicle 10 is predefined in which it is intended to establish whether first-aid measures are required.By an indication of a first responder 12, the vehicle 10 recognizes whether a first-assist measure is required. The first responder 12 is indicated acoustically inside or outside the vehicle 10 in this exemplary embodiment. The acoustic cue is a signal word that is called out by the first responder 12. In the present exemplary embodiment, "help" is used as the signal word. A common signal word used in certain situations can also help first responders 12 who do not know that vehicle 10 has such an assistance function. In an emergency situation, it is obvious to call "help". This may be registered by the vehicle 10.In darkness, an area around the radius 16 around the vehicle 10 is illuminated. In this case, various lighting devices 18 of the vehicle 10 are used for illumination. In particular, headlights 20 are used. Likewise, bending lights, side lights in exterior mirrors, tail lights, backup lights and others may be used. Such illumination or illumination simultaneously serves as a signal effect for other road users who can additionally provide assistance.The vehicle 10 further determines whether the injured person 14 who needs a first-aid action is an adult person or an infant. The distinction is relevant, for example, for performing cardiac pressure massages. In an adult human, a greater pressure is required than in an infant. The ascertainment is carried out by evaluating data of a vehicle camera 22 In order to provide the first responder 12 with a suitable assistance for a possibly necessary cardiac massage, a clock for a reanimation is output as part of a first-assistance measure by means of available loudspeakers 24 of the vehicle 10. In addition, a clock for a reanimation is output by the headlights 20 of the vehicle 10 within the scope of a first-aid measure. An output clock, both visual and acoustic, helps a first responder 12 to maintain the correct frequency, for example, during a cardiac massage, or to give him an indication of how often pressure should be exerted on the chest of an injured person 14 in the minute. The predetermined cycle can serve as an orientation for the first responder 12 so that a correct execution of the first-aid measure can be achieved.By means of an UltraIdeBand antenna 26 of the vehicle 10, a necessary indentation depth is measured for a cardiac massage within the scope of the first-aid measure. In this way, it is possible to measure accordingly how deep, for example, the rib cage of an injured person 14 is pressed in by the first responder 12. By comparing with reference values, it can then be checked, for example, whether the first-aid measure is carried out correctly or whether adaptations are necessary. Loudspeaker 24 of the vehicle 10 outputs additional acoustic indications which contain an aid to the necessary impression depth. In this embodiment, voice announcements are output by speakers 24, which output unique alerts to first responder 12 as to whether or not the first help action is being performed correctly. In the voice announcements, words such as "stronger", "weaker" or "correct" are used to communicate to the first responder 12 both if the first-aid action can be improved or if the first-aid action is already carried out correctly.In addition, a visual assist for performing the first assist action is projected onto the ground in the vicinity of the vehicle 10 by the vehicle 10. For this purpose, a matrix LED light 30 is provided, through which a heart 32 is projected onto the ground. A light carpet 34 is placed around this heart 32. When the chest is pressed in during a reanimation, the light carpet 34 collapses into the heart 32. When the impression depth is sufficient, the entire light carpet 34 falls in, and when the pressure is too weak, a part of the light carpet 34 remains stationary. In addition, with the impression depth correct, a hook 36 is displayed as an indication of the correct execution. In this way, the first responder 12 is provided with an easily comprehensible and highly visible instruction as to how the first-aid measure is to be carried out.FIG. 2 shows a schematic block diagram of various steps of a method for optimizing first-aid measures. In step 100, the vehicle 10 recognizes the need for reanimation by an acoustic notice of a first responder 12. In step 102, visual and audible capabilities of the vehicle 10, both inside and outside, are subsequently performed to assist the first responder 12 in performing reanimation actions. For this purpose, provision is made in step 104 for checking whether, owing to darkness, illumination of the direct environment around the vehicle 10 by means of the headlights 20 or other light sources of the vehicle 10 is necessary in order to supply persons brought into the outer region with sufficient brightness.In step 106, it is checked whether the reanimator is an adult or an infant. This applies only to recognized vehicle occupants or persons outside the vehicle within the visibility range of the vehicle camera 22, for example an interior camera, front camera, side camera and / or rear camera.In step 108, a clock for reanimation is output over all the interior and exterior speakers. Accordingly, a clock is additionally output over all the interior and exterior lights for reanimation. Lights and sounds are synchronous.In step 110, the required impression depth in the event of a cardiac massage is measured by means of the UltraIdeBand antenna 26 and is passed on to the first responder 12 by means of acoustic signals.Additionally, in step 112, a visual aid is projected onto the ground by means of the matrix LED light 30, which projects images moved in real time to the first responder 12 onto the ground, by means of which the first responder 12 is directed to correctly carry out the first aid measures.List of reference characters10 Vehicle 12 First responder 14 Injured person 16 Radius 18 Lighting device 20 Headlight 22 Vehicle camera 24 Loudspeaker 26 UltraIdeBand antenna 30 Matrix LED light 32 Heart 34 Light carpet 36 Hook 100 Detection of first aid measure 102 Performance of visual and acoustic possibilities 104 Checking whether lighting is necessary 106 Checking whether infants or adults 108 Output clock for reanimation 110 Measurement and signaling of the impression depth 112 Projecting visual aid
