The invention relates to a method for operating an emergency assistance system for a motor vehicle, in which, in the event of an accident of the motor vehicle, an automatic emergency call is made to a rescue control center by means of the emergency assistance system, and in which at least one piece of information relating to the accident of the motor vehicle is provided by an electronic computing device external to the vehicle of the emergency assistance system is transmitted to an ambulance by means of a cellular connection. The invention also relates to an emergency assistance system.

It is already known from the prior art that motor vehicles can trigger so-called e-calls if, for example, an accident is detected by the motor vehicle. These e-calls are automatically triggered electronic rescue calls from the motor vehicle that an accident has occurred, which then automatically contacts a rescue control center. The rescue control center can then, in turn, carry out a corresponding disposition of the resources and the emergency services, for example ambulances. The emergency services then take over the corresponding operation and move out, for example, to set off for the accident victim and the car that has been involved in the accident.

the DE 10 2015 219 189 A1 relates to an apparatus for detecting an emergency situation of a vehicle including: a sensor unit formed with one or more of a speed sensor, a wheel sensor, an acceleration sensor, a lateral acceleration sensor, a yaw rate sensor, and an inclination sensor; an emergency situation determination unit that receives a signal from the sensor unit and determines whether a driver's vehicle is in an emergency situation; and a communication unit that creates at least one of an emergency situation message representing the emergency situation of the driver's vehicle and a release message representing the release of the emergency situation according to the determination result of the emergency situation determining unit, the message of an external emergency situation Broadcasting device sends and enables the emergency situation broadcasting device to broadcast an emergency broadcast state of the driver's vehicle to the outside. Accordingly, when information that a vehicle is in an emergency situation is collected, the emergency situation is verified within a predetermined standby time and notified to a rescue center, a roadside unit, a nearby vehicle and the like, thereby making it possible to get over the rescue center quickly to inform the emergency situation of the vehicle and provide accurate information, thereby achieving an efficient rescue.

the DE 10 2012 016 241 A1 relates to a method for sending an electronic call for help from a crashed motor vehicle, in which the call for help can be sent using short-range radio data technology and can be received by conventional mobile terminals in the vicinity of the scene of the accident. The electronic call for help is triggered by an acceleration signal and / or the activation signal of a safety system.

the DE 10 2010 028 613 A1 relates to wireless vehicle-to-X communication via radio keys with a transceiver. The radio key transceiver is designed to send and receive not only data of the keyless driving authorization, but also vehicle-to-X communication data. Radio key X communication can be used between two vehicles equipped with this radio key communication technology in order to quickly and reliably communicate data such as positions, weather conditions or warnings. This wireless communication technology using a radio key can also be used to coordinate emergency services when looking for an accident on site.

the DE 2009 015 513 A1 relates to an emergency call unit for a vehicle which, in addition to a detection unit and a position detection unit and a control unit, has a transmission unit for repeatedly transmitting a locating signal to a rescue worker. The location signal can correspond to the position of the vehicle and the transmission of the location signal is triggered by a trigger event. The trigger event is, for example, a request from a rescue worker or the detection of an accident.

The object of the present invention is to create a method and an emergency assistance system by means of which an improved rescue of an injured occupant of an injured motor vehicle can be realized.

This object is achieved by a method and by an emergency assistance system according to the independent patent claims. Advantageous embodiments are specified in the subclaims.

One aspect of the invention relates to a method for operating an emergency assistance system for a motor vehicle, in which, in the event of an accident in the motor vehicle, an automatic emergency call is made to a rescue control center by means of the emergency assistance system, and in which from At least one piece of information relating to the accident of the motor vehicle is transmitted to an ambulance by means of a mobile radio connection to an electronic computing device of the emergency assistance system external to the vehicle.

It is provided that at least one piece of personal information relating to an occupant of the motor vehicle is transmitted from the motor vehicle to the ambulance via close-range communication.

This enables the ambulance to have information about the occupant at an early stage, in particular even before arrival at the scene of the accident, based on the occupant's personal information, so that an improved rescue can be carried out.

The personal information can be, for example, a past clinical picture of the occupant. For example, should the occupant have diabetes, this personal information can be transmitted to the ambulance via the short-range communication.

According to the invention, ambulances are to be understood as meaning in particular emergency services. Thus, an ambulance can be understood to mean, for example, a fire brigade, an ambulance or a police force.

In particular, so-called vehicle-to-X communication can be viewed under short-range communication. This can be, for example, a WiFi network, an IST G5 or a 5G network. A ZigBee network can also be used for this purpose. In this short-range communication, it can be provided in particular that vehicles can exchange and communicate with one another in the short-range. It is also possible to communicate with the infrastructure, for example with traffic lights or traffic control systems.

Furthermore, it can in particular be provided that the personal information is transmitted at least in encrypted form from the motor vehicle to the ambulance. This makes it possible for other participants not to be able to access the corresponding personal information.

In particular, this makes it possible for highly up-to-date data about the motor vehicle and about the at least one occupant to be transmitted to the ambulance, so that the ambulance or the rescue services can rescue the occupant in an improved manner.

In this way, personal information can be included to support the rescue workers both in preparation and in the implementation of the mission. Both static and dynamic personal information can be used. When an accident is detected, the at least one piece of personal information is transmitted to the emergency services and, in particular, this personal information can also be updated at regular intervals.

According to an advantageous embodiment, medical information about the occupant is additionally transmitted from the electronic computing device external to the vehicle to the ambulance by means of the mobile radio connection. For example, the electronic computing device external to the vehicle, which can also be referred to as a backend, can request the occupant's medical record from a health insurance company. The medical file can then also be transferred to the ambulance. This medical record can then in turn be transmitted to the ambulance, in particular via mobile radio, so that the ambulance receives information about the occupant's medical history. An improved rescue of the occupant can thus be realized.

Furthermore, it has proven to be advantageous if the personal information is recorded and / or stored by a mobile terminal connected to the motor vehicle. For example, the mobile terminal can be a smartphone of the occupant. Correspondingly, personal information, such as high blood pressure or a medical history, can be stored here, with the personal information then being able to be transmitted to the ambulance in turn. Furthermore, so-called wearables, for example intelligent watches, so-called smart watches, can also transmit current vital data, such as pulse, blood pressure or oxygen saturation, to the ambulance. As a result, the ambulance can initiate appropriate measures even before it arrives in order to be able to carry out an improved rescue of the occupant.

It is also advantageous if current vital data of the occupant is transmitted as personal information to the ambulance by means of the short-range communication. For example, the current pulse rate, the current oxygen saturation and the current blood pressure can be viewed as vital data. These vital data can then be transmitted to the ambulance in the most up-to-date manner by means of close-range communication. In particular, the vital data can be transmitted to the ambulance at regular intervals, so that these can flow into the rescue measures at an early stage in order to be able to carry out an improved rescue of the occupant.

In a further advantageous embodiment, a first-aid register for trained first-aiders is provided on the electronic computing device external to the vehicle, and a notification of the accident is transmitted to the first-aid provider as a function of a position of a first-aid provider registered in the first-aid register. In particular, a large number of first aiders can be registered within the first aid register. If a motor vehicle with a first aider is in the vicinity of the accident, this can be registered by means of the emergency assistance system and a corresponding message can be transmitted to the first aider that an accident vehicle is in his vicinity. In this way, a first aider can begin with the appropriate rescue measures for the occupant before the ambulance arrives. As a result, help can be provided as quickly as possible by calling in trained first aiders in the event of an accident. The first aid register contains information and contact details for first aiders in particular. If there is an accident, a message with relevant data is sent to the first aider for a first rescue and a request for available first aiders is sent to this database. The electronic computing device external to the vehicle uses a list to determine the registered first aiders in the vicinity of the accident and forwards a request message to the first aid provider.

It is also advantageous if the personal information of the occupant is transmitted to the first aider by means of the short-range communication. For example, a current pulse can be transmitted to the first aider so that he or she already knows before arriving at the scene of the accident whether the occupant still has a pulse or whether, for example, a corresponding chest compressions must be initiated. An improved rescue of the occupant can thus be realized.

It is also advantageous if further information relating to the accident is transmitted to the first aider. For example, a position of the accident and a number of occupants as well as a number of motor vehicles involved in the accident can be communicated to the first aider. If, for example, it is found that a large number of motor vehicles are involved in the accident, several first aiders can also be provided with the corresponding information so that the occupants can be rescued at an early stage. In particular, this can be done via the short-range communication.

It is also advantageous if at least the personal information is transmitted to a further first aider if the first aider addressed first should not confirm the order for first aid from the emergency assistance system. In particular, it can thus be provided that, for example, a notification to the first aider is transmitted to an instrument cluster of the motor vehicle. The first aider must then confirm the order for first aid. If the first aider does not do this, i.e. does not confirm the order, at least one further first aider is contacted by means of the emergency assistance system so that the occupant can be rescued by the further first aider.

It is also advantageous if an accident message about the accident motor vehicle is transmitted to other road users by means of close-range communication. In particular, for example, a position of the motor vehicle involved in the accident can be transmitted to the other road users, in particular other motor vehicles. For example, they can then bypass the scene of the accident or start creating an emergency lane at an early stage. This enables the occupant to be rescued more quickly.

Another aspect of the invention relates to an emergency assistance system for a motor vehicle, with at least one electronic computing device external to the vehicle and with a mobile radio connection, the emergency assistance system being designed to carry out a method according to the preceding aspect. In particular, the method is carried out by means of the emergency assistance system.
