DETAILED DESCRIPTION

[0054] FIG. 1 shows a block diagram of an emergency system 100 according to a first embodiment. The emergency system 100 has a data collection unit 101, which is formed for collecting and combining emergency data. The data collection unit 101 may be arranged, for example, within a vehicle. However, it is also possible for the data collection unit 101 to be arranged outside of a vehicle and/or in a portable device.

[0055] The emergency data in the example comprise vehicle data 110, medical data 120, and correlation data 130.

[0056] In order to record vehicle data, the emergency system 101 has an interface 114 for vehicle data 110, which is connected to the data collection unit 101. The interface 114 is preferably arranged within a vehicle and expediently has access to data and records of an accident sensor 115, airbag and seat settings 116, as well as interior cameras 117. The interior cameras in this case can be designed for recording 2D, 3D, and/or infrared images. The type and severity of an accident can be determined solely from the information as to whether and which airbags have been deployed. The seat sensors can provide information, for example, as to how many users are in the vehicle. These data are thus very important for estimating an accident situation.

[0057] The emergency system 100 further comprises a position unit 111, which is connected to the data collection unit 101 in the example. However, it may also be advantageous when the position unit is connected to the interface for vehicle data 114, and the vehicle data collected are transferred to the collection unit. The position unit 111 is connected to a satellite navigation unit 112 and/or to environment cameras 113, which are used to determine the current vehicle position. Particularly modern passenger cars frequently have so-called 360° cameras which can also provide, for example, an impression of the accident environment. For example, it can be determined whether and possibly how many pedestrians or bicyclists, who may not have any emergency system, are involved in the accident.

[0058] In order to record medical data 120, the emergency system has an interface 121 for medical data 120, which is connected to the data collection unit 101. On the one hand, the interface 121 for medical data 120 is connected to vehicle sensors 122 for medical data 120. These vehicle sensors 122 can provide, for example, real-time data such as, for example, pulse, oxygen saturation, or respiration rate. The vehicle sensors can also provide dynamic medical data. The vehicle sensors 122 can be integrated, for example, into seats, seatbelts, armrests, headrests, or into the steering wheel and can function via direct contact or without contact. To this end, the vehicle sensors 122 may also have lasers, cameras, and/or stereo cameras.

[0059] The interface 121 can also be connected to remote sources 123 for medical data 120, for example, via a wireless communication link. Remote sources 123 may contain dynamic, quasistatic, and/or static medical data 120. A remote source may be, for example, a portable and/or implanted device, a stationary home emergency system, or even an electronic medical record of the user. The interface 121 can communicate with any data sources in many different ways in this case, such that a comprehensive medical profile of a user is available.

[0060] The medical data in this case may comprise values related to age, sex, height, weight, blood type, body mass index (BMI), allergies, illnesses, implants, pulse, blood pressure, blood glucose, blood transfusion history, transplant history, seeing and/or hearing aids, pacemakers, blood alcohol, and/or the influence of drugs. The list can be supplemented with any medical data depending on the availability of data and is not limited to the examples mentioned herein.

[0061] The data collection unit 101 is connected to a data storage unit 140, in which the collected emergency data are stored. The data storage unit 140 may have a local data storage 141 and/or a remote data storage 142. A remote data storage 142 may be, for example, a cloud storage accessible via the Internet.

[0062] In order to access the emergency data, the emergency system 100 has a data access unit 150 which is connected to the data storage unit 140 via a communication link 182. The data storage unit 140 can be permanently installed in the vehicle or may be arranged in a portable device. However, the data storage unit 140 may also be arranged stationary outside of a vehicle. The connection 181 between the data collection unit 101 and the data storage unit can accordingly be wired and/or wireless. For this reason, the communication link 182 between the data storage unit 140 and the data access unit 150 may also be wired and/or wireless. In this case, various technologies can be used, which is why the application is not limited to a specific connection.

[0063] In order to record correlation data 130, the emergency system 100 has a correlation unit 131 in the example. To this end, the correlation unit 131 may be connected, for example, to a device for recording the road conditions 132 and/or to a different source 133 for correlation data 130. Correlation data 130 may also comprise, for example, information from social networks or other Internet platforms. The correlation data enable, for example, a more precise interpretation of the collected emergency data. Thus, it can be determined, for example, from the position and the link to other data, that a user was just in a fitness studio and accordingly a pulse determined to be higher is normal and does not represent any medical indication. In this manner, different situations may also possibly be evaluated differently than the pure data situation permits.

[0064] The correlation unit 131 is connected directly to the access unit 150 in the example. This means that the correlation data is not in the data storage unit 140 but can be read out directly. In an alternative embodiment, the correlation unit 131 may also be connected, however, to the data collection unit 101 such that the correlation data 130 are part of the emergency data.

[0065] The data access unit 150 is the interface via which, for example, an emergency call center 160 and/or a trauma center 170 can obtain access to the emergency data. However, this access is only possible when the emergency system 100 is in foreground mode. The foreground mode is activated by a trigger mechanism.

[0066] The emergency system 200 shown in FIG. 2 is essentially identical to the emergency system from FIG. 1. Thus, equivalent features are provided with the same reference numeral. The emergency system 200 additionally has, however, an analysis unit 290, which is arranged between the data collection unit 101 and the data storage unit 140. The analysis unit 290 may have a local computing unit 291 and/or a remote computing unit 292, in which the collected emergency data can be analyzed.

[0067] FIG. 3 schematically shows the various states of the emergency system 101. The emergency system is OFF at point in time T0. This is the case, for example, when the vehicle is switched off. The vehicle is switched on at point in time T1. The emergency system is thereby activated and switched to background mode (HG). In background mode, it is not possible to establish a communication link via the data access unit. At point in time T2, a trigger mechanism is activated, whereby the emergency system is switched to foreground mode (VG). In foreground mode, a communication link is established between the data access unit and the data storage unit, by means of which, for example, an emergency call center can retrieve relevant emergency data or the data can be transferred thereto.

[0068] FIG. 4 shows various trigger mechanisms of an emergency system. The emergency system in this case has a manual trigger mechanism 400. The manual trigger mechanism can be activated manually by a user in order to report, for example, a situation which was not detected as an emergency by the data collection unit based on the collected data.

[0069] The emergency system additionally has a semi-automatic trigger mechanism 401. In this case, the emergency system detects an emergency based on the collected data but it is not critical or requiring immediate action. With this trigger mechanism 401, a manual confirmation 402 by a user is required in order to actually activate the trigger mechanism. A maximum wait time can be specified for the confirmation. Once the wait time has expired without manual confirmation, the emergency system can be configured such that the trigger mechanism is activated or not activated. This can depend, for example, as well on the type of emergency supposedly detected.

[0070] The emergency system further has an automatic and autonomous trigger mechanism 403, which is activated by the emergency system. These can be clearly determinable emergencies such as, for example, an accident in which the vehicle sensors provide clear signals. This can be determined, for example, by an explicit accident sensor, rollover sensor, or deployed airbags.

[0071] If one of the trigger mechanisms is activated and possibly confirmed, the emergency system switches to foreground mode 404.

[0072] FIG. 5 shows a flowchart of a method for triggering an emergency. First, the vehicle is started in one step 500. The emergency system is thereby switched into background mode and thus activated. Then the users of the vehicle are identified 502. This can take place through biometric detection or through other features. During the trip, emergency data of all users are accordingly then continually collected 504. In this case, the emergency data can be constantly updated, for example, through a readout of vehicle sensors. The emergency data are then evaluated 506 in order to detect an emergency. After evaluation of the emergency data, there is a check 508 to determine if an emergency is at hand. If this is not the case, further emergency data are collected 504. If an emergency is detected, a trigger mechanism is activated 510, as is explained, for example, in FIG. 4.

[0073] FIG. 6 shows a flowchart of a method for alerting a rescue means after the activation of a trigger mechanism 600. The emergency system activates 602 the foreground mode, whereby a communication link is established between a data access unit and the data storage unit. An emergency call center can then retrieve the emergency data 604 and alert suitable rescue means 606.
