AI Technical Summary

Technical Problem

Existing methods for determining vital functions of vehicle occupants, such as cardiogram signals, are inaccurate and inconvenient, especially when integrated into motor vehicles, and do not allow for precise medical emergency detection without direct skin contact.

Method used

A magnetic field sensor device, specifically a gradiometer with two nitrogen-vacancy sensors, is integrated into a vehicle seat to measure magnetocardiogram signals, which are processed by an evaluation unit to determine vital functions, filtering out environmental interference and providing accurate cardiac emergency detection.

Benefits of technology

Enables precise and convenient detection of vital functions, allowing early detection of medical emergencies and enabling safe vehicle control measures, such as emergency stops, without inconveniencing the occupant.

Abstract

In order to provide a method for determining the vital functions of a vehicle occupant, which allows for accurate measurements and is easy to use without disturbing the vehicle occupant, the invention relates to a method (100) for determining the vital functions of a vehicle occupant (10), wherein by means of a sensor device (13) incorporated in a vehicle seat (10) of a motor vehicle, measurement signals of a vehicle occupant (10) are determined from which cardiogram signals can be determined, wherein an evaluation unit (19) determines the vital functions of the vehicle occupant (10) from said cardiogram signals, wherein it is further provided that the sensor device (13) is a magnetic field sensor device (14) and that the cardiogram signals are magnetic cardiogram signals.
