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.
