## Abstract

A situation in which a person located in a vehicle suffers a medical emergency is detected and aid measures are provided. Vital data is examined for deviations from predefined standard values. If a deviation be identified an alert is output in the vehicle. A communications link is established to an aider external to the vehicle the aider is granted access to at least some of the vital data and to the control of vehicle functions. A microphone and a loudspeaker are activated to establish a bidirectional verbal communications link between vehicle occupants and aider and a camera, which captures at least a portion of a vehicle interior, to transfer camera images to the aider. The aider can talk to the vehicle occupants, visually examine the person, and propose suitable aid measures. The aider controls at least one vehicle function in order to facilitate the examination and/or assist the person.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

A method for detecting a situation in which a person located in a vehicle suffers a medical emergency and for providing assistance, the method comprising:
detecting, by at least one sensor, vital signs of the person;
evaluating, by a computing unit, sensor data generated by the sensor to determine vital data;
outputting, by the computing unit and based the vital data in the vehicle, instructions for providing assistance to the person in the situation;
examining, by the computing unit, the vital data for deviations from standard values;
causing, by the computing unit when the examination identifies the deviations from the standard values, an alarm to be output in the vehicle;
establishing, by the computing unit using a telecommunications unit, a communications link to an aider external to the vehicle;
granting, by the computing unit, the aider access to at least some of the vital data;
activating, by the computing unit, a microphone and a loudspeaker to establish a bidirectional verbal communications link between occupants of the vehicle and the aider; and
capturing, by a camera, at least a portion of a vehicle interior to transfer camera images to the aider, wherein the aider is then able to talk to the vehicle occupants, to visually examine the person, and to propose measures for aiding the person based on an examination result,
wherein person-specific standard values are established that the computing unit takes into account when examining the vital data for the deviations,
wherein the computing unit only establishes the communications link to the aider if establishing the communications link to the aider is not proactively prevented by a vehicle occupant, and
wherein the computing unit grants the aider access to the control of vehicle functions so that the aider controls at least one vehicle function to facilitate the examination or to aid the person.

### Claim 11 (depends on 10)

The method of claim 10, wherein the aider controls at least one of the following vehicle functions:
adjusting a seat;
switching interior lighting on or off;
adjusting a vehicle AC unit;
actuating a window regulator; and
adjusting seat heating.

### Claim 12 (depends on 10)

The method of claim 10, wherein the detected vital signs and the determined vital data allows assessment of a state of the cardiovascular system of the person.

### Claim 13 (depends on 10)

The method of claim 10, wherein the at least one sensor is a vehicle-integrated sensor or is integrated in a mobile end device worn or carried by the person.

### Claim 14 (depends on 10)

The method of claim 10, wherein examination-relevant information or the suitable measures for aiding the person are output visually in the vehicle.

### Claim 15 (depends on 10)

The method of claim 10, wherein at least some of the vital data is forwarded to third parties, wherein at least some of the vital data is transferred from the vehicle to the aider, and from the aider to a central computing unit external to the vehicle, via which the third parties are granted access to at least some of the vital data.

### Claim 16 (depends on 10)

The method of claim 10, wherein the alarm is output in the vehicle haptically, visually, or acoustically.

### Claim 17 (depends on 10)

The method of claim 10, wherein
the alarm is also output external to the vehicle visually or acoustically, or
the vehicle is automatically brought to a standstill when the alarm is output.

### Claim 18

A first aid system for detecting a situation in which a person located in a vehicle suffers a medical emergency and for providing assistance, the first aid system comprising:
a vehicle comprising a computing unit, a telecommunications unit, a human-machine interface, and a camera; and
at least one sensor,
wherein the at least one sensor is configured to detect vital signs of the person,
wherein the computing unit is configured to
evaluate sensor data generated by the sensor to determine vital data;
output, based the vital data in the vehicle, instructions for providing assistance to the person in the situation;
examine the vital data for deviations from standard values;
cause, when the examination identifies the deviations from the standard values, an alarm to be output in the vehicle;
establishes, using the telecommunications unit, a communications link to an aider external to the vehicle;
grants the aider access to at least some of the vital data; and
activate a microphone and a loudspeaker to establish a bidirectional verbal communications link between occupants of the vehicle and the aider;
wherein the camera is configured to capture at least a portion of a vehicle interior to transfer camera images to the aider, wherein the aider is then able to talk to the vehicle occupants, to visually examine the person, and to propose measures for aiding the person based on an examination result,
wherein person-specific standard values are established that the computing unit takes into account when examining the vital data for the deviations,
wherein the computing unit is configured to only establish the communications link to the aider if establishing the communications link to the aider is not proactively prevented by a vehicle occupant, and
wherein the computing unit is configured to grant the aider access to the control of vehicle functions so that the aider controls at least one vehicle function to facilitate the examination or to aid the person.
