Description

The invention relates to a method and a device for supplying a vehicle occupant of a vehicle in an emergency situation.

In future automated vehicles, it will be more common for people to be transported alone. In a medical emergency, the person being transported must be helped quickly.

From the DE 10 2015 011 319 A1 a method for improving the driving safety of a vehicle is known. The method comprises the following steps: determining the state of the driver; Determining whether the specific state of the driver can be viewed as undesirably influencing driving safety; and if so, activating certain measures beforehand so that driving safety is improved. The method further comprises the following steps: storing cases of activation of the previously determined measures; and providing the cases of activation of the previously determined measures stored in this way for future actions to improve driving safety.

The invention is based on the object of improving a method and a device for supplying a vehicle occupant of a vehicle in an emergency situation.

The object is achieved according to the invention by a method having the features of claim 1 and a device having the features of claim 10. Advantageous embodiments of the invention emerge from the subclaims.

In particular, a method for supplying a vehicle occupant of a vehicle in an emergency situation is made available, with biometric data of the vehicle occupant being recorded by means of a sensor system, with a checking device being used to check whether the recorded biometric data exceed at least one predetermined threshold value, and with one If at least one predetermined threshold value is exceeded, measures are initiated by means of a control device as a function of escalation levels assigned to each threshold value.

Furthermore, in particular, a device for a vehicle for supplying a vehicle occupant of the vehicle in an emergency situation is created, comprising a sensor system or an input interface for capturing or receiving biometric data of the vehicle occupant, a checking device, and a control device, the checking device being designed in such a way check whether the captured biometric data exceed at least one predetermined threshold value, and wherein the control device is designed to initiate measures as a function of escalation levels assigned to threshold values when at least one predetermined threshold value is exceeded.

The method and the device make it possible to react to an emergency situation in an automated and in particular improved manner. This is made possible by initiating measures after the occurrence of an emergency situation depending on escalation levels. In this way, an aid measure tailored to the specific emergency situation can be initiated. It is also possible to go through escalation levels in an orderly manner depending on the course of the emergency situation. To determine the emergency situation, biometric data of a vehicle occupant are recorded by means of a sensor system. A checking device continuously checks whether the biometric data exceed at least one predetermined threshold value. It can be provided here that a state of health of the vehicle occupant is estimated from the biometric data. Alternatively or additionally, the state of health can also be compared with predetermined threshold values or threshold states (“health thresholds”) or when they are reached or exceeded. Escalation levels are assigned to the threshold values. The same or more escalation level (s) can be assigned to a threshold value or several threshold values. If at least one threshold value is exceeded, a control device initiates at least one measure as a function of the escalation levels assigned to each of the threshold values. In particular, it can be provided that (all) combinations of reached or exceeded threshold values are each uniquely assigned escalation levels.

The method and the device are described for a vehicle occupant. However, it can also be provided that the method and the device are applied to several vehicle occupants.

The sensor system can in particular include one or more of the following sensors: pulse sensor, sweat sensor, blood pressure sensor, electrocardiogram sensor (ECG / EKG), eye movement sensor, odor sensor, breathing sensor, camera, speech recognition, pulse rate sensor, motion sensor or body temperature sensor.

The biometric data recorded by means of the sensor system include, in particular, current values of vital functions of the vehicle occupant, such as heart rate, blood pressure, skin or body temperature, respiratory rate, oxygen saturation of the blood etc. Based on biometric data recorded by means of the sensor system, a Health status of the vehicle occupant can be estimated.

The threshold values correspond in particular to the biometric data or to values of vital functions (heart rate, blood pressure, skin temperature, etc.) of the vehicle occupant. Depending on the type of threshold value (heart rate, skin temperature, blood pressure, etc.) it can be provided that several or specific combinations of threshold values must be exceeded so that an escalation level can be identified or selected. The combinations of the threshold values are or are, in particular, selected in such a way that they coincide with defined health conditions and / or medical diagnoses. In other words, the threshold values are determined in particular on the basis of medical criteria, for example by a doctor treating the vehicle occupant and / or on the basis of personal or general empirical values.

The vehicle is in particular a motor vehicle. In particular, the vehicle is a partially or automatically driven vehicle. In principle, however, the method and the device can also be used in other land, air, water or space vehicles.

Parts of the device, in particular the checking device and / or the control device, can be designed individually or collectively as a combination of hardware and software, for example as program code that is executed on a microcontroller or microprocessor. However, it can also be provided that parts are designed individually or combined as an application-specific integrated circuit (ASIC).

In one embodiment it is provided that the predetermined threshold values and / or escalation levels and associated measures are predetermined or are predetermined as a function of the vehicle occupant. In particular, it can be provided that a vehicle occupant stores a measure profile in which threshold values are stored linked to escalation levels and measures are defined for the individual escalation levels. In this way, a tailor-made catalog of measures can be kept ready for a vehicle occupant, especially if their health is already at risk or has known pre-existing illnesses. In particular, health conditions can be defined in such a measure profile using biometric data or predetermined threshold values, which are then linked to individual escalation levels and measures. The measure profile of the vehicle occupant can be transmitted wirelessly from a smartphone to the device, for example, or can also be fed to the device by means of another data carrier.

In one embodiment it is provided that an escalation level is selected or changed as a function of a lapse of time. For example, it can be provided that after the occurrence of an emergency situation, a measure corresponding to a first escalation level is initiated. Depending on or regardless of whether the measure was successful, a jump can be made to a second escalation level, which provides for one or more other measures, when a certain period of time has expired. In this way, a specified procedure can be followed when initiating the measures.

In one embodiment it is provided that an escalation level is selected or changed as a function of at least one further parameter. Another parameter can be, for example, a time of day, a location, a weather or the weather, a vehicle condition or personal specifications of the vehicle occupant. In this way, it is possible in particular to react to external or other circumstances of the emergency situation and to select or change the escalation level depending on the external or other circumstances.

One embodiment provides that at least one specified contact person outside the vehicle is contacted by means of a communication device at an escalation level as a measure. Such a person can in particular be a family member, a relative and / or a carer or carer for the vehicle occupant. For this purpose, telephone numbers and / or other contact details of the at least one specified contact person are stored in the control device, for example. It can also be provided that contact persons are contacted one after the other according to a predetermined order of priority, the next person being contacted in each case if the person in front cannot be reached.

It can be provided that a contacted contact person can access a history of the biometric data. For this purpose, the biometric data are transmitted to the contact person by means of the communication device.

One embodiment provides for at least one doctor and / or a medical facility to be contacted by means of a communication facility at an escalation level as a measure. For this purpose, telephone numbers and / or other contact details of the at least one doctor and / or the medical facility are stored in the control device. It can also be provided that the control device searches for suitable doctors and / or medical facilities in the current surroundings of the vehicle, for example by means of an address, telephone book or Internet search. The communication device can be the same as in the embodiment described above.

It can be provided that the specified contact persons and / or the at least one doctor and / or the medical facility are contacted as a function of an estimated state of health of the vehicle occupant. This makes it possible to contact different contact persons or different doctors or different medical institutions depending on a clinical picture. For example, a different medical facility can be contacted in the case of an acute heart attack than in the case of visual disturbances.

In one embodiment it is provided that a first escalation level provides for contacting the at least one specified contact person, a second escalation level providing for contacting the at least one doctor and / or the medical facility, with a change from the first to the second escalation level if the at least a specified contact person was not reached after a specified period of time.

In one embodiment it is provided that an optical and / or acoustic signal is output by the vehicle at an escalation level as a measure in order to signal an emergency. In this way, the presence of an emergency situation in the vehicle can be signaled to people in the vicinity of the vehicle. The acoustic and / or optical signal can be provided, for example, by means of a horn or a signal horn and / or the hazard warning system of the vehicle.

In one embodiment it is provided that an emergency request is transmitted to at least one further person and / or at least one further vehicle at an escalation level as a measure by means of a communication device, with the emergency request being sent to the at least one further person and / or or the at least one further vehicle is displayed. In particular, the at least one further person can be a person who has identified himself as an emergency helper in some form, for example via an emergency system and / or via an app. The same applies to a person who drives in the at least one other vehicle. In this way, people in the vicinity of the vehicle can be contacted in a targeted manner who are able and qualified to help quickly.

In one embodiment it is provided that the vehicle is automatically driven on an escalation level as a measure to a destination where medical care can be provided. This can be, for example, a hospital in the vicinity or a clinic specializing in an (estimated) state of health of the vehicle occupant.

In a further developing embodiment, it is provided that the destination is selected as a function of a further person and / or at least one further vehicle located in the vicinity. This makes it possible, for example, to specifically drive a doctor or emergency doctor driving in another vehicle and / or an emergency vehicle in the vicinity. As a result, a waiting time until the vehicle occupant is (first) supplied can be shortened.

In a further further developing embodiment it is provided that the destination is selected as a function of a landing position of a transport drone. In this way, for example, required medication can be quickly transported to the selected destination using the transport drone and received there. For example, a request for a required drug can be transmitted to a supply system of a service provider via a communication link. The supply system then notifies the requesting vehicle or the device of a landing position of the transport drone. The vehicle then automatically drives to the landing position selected as the destination.

In one embodiment, it is provided that, as a measure, the vehicle occupant is woken up at an escalation level and / or it is checked whether the vehicle occupant can be addressed. In this way, in particular a medical, in particular a mental, condition of the vehicle occupant can be checked. On the basis of a check result, you can either switch to another escalation level or the procedure can be ended.

In one embodiment it is provided that, at an escalation level, first aid instructions on a display and operating device of the vehicle and / or with the vehicle via a communication device as a measure connected smartphone or augmented reality glasses. As a result, a helping person can be provided with assistance in carrying out first aid measures.

It can be provided that a translation function is additionally provided on the display and operating device. A helping person can then, for example, be asked for a desired language at the beginning of the first aid measures. The first aid instructions are then provided in or translated into a language selected by the helper. This is done in particular by means of a translation device, which can be part of the display and operating device or the control device, for example.

In one embodiment, it is provided that a telemedical communication connection is set up at an escalation level as a measure by means of a communication device, via which a doctor and / or a medical institution can provide and / or support medical (initial) care. In particular, it can be provided that the captured biometric data and captured camera images etc. are transmitted to the doctor and / or the medical facility via the telemedical communication link.

It can be provided that the control device estimates a diagnosis and / or prognosis of a health status of the vehicle occupant on the basis of the biometric data, in particular by means of artificial intelligence, for example on the basis of machine learning methods, and the estimated health status for a helping person and / or a specified contact person and / or a contacted doctor and / or a contacted medical facility transmitted. As a result, a first diagnosis and / or prognosis can be made available from the very beginning or at least at an early stage, whereby, for example, the initiation of further measures can be accelerated.

Further features for the configuration of the device emerge from the description of configurations of the method. The advantages of the device are in each case the same as in the embodiments of the method.
