Abstract

There is provided a method and system for operating a vehicle when a vehicle occupant experiences a potential medical condition. The system may include an external object control module (EOCM) configured to wirelessly receive diagnostic signals from an occupant-coupled device, such as a smart watch or implanted cardiac pacemaker. The method and system process the diagnostic signals, for example by determining the nature and/or severity of the potential medical condition and carrying out one or more responses in reaction thereto. The type of response carried out can depend on whether the occupant is a driver or passenger, as well as the nature and/or severity of the potential medical condition, and can range from giving medical instructions to vehicle occupants to automatically slowing the vehicle down and bringing it to a safe stop in the event that the driver is unable to do so.

7. The method of claim 6, wherein the analyzing step further comprises obtaining a heart rate reading from the received diagnostic signal, obtaining a heart rate threshold from the retrieved medical profile, comparing the heart rate reading to the heart rate threshold, and determining that the occupant to whom the occupant-coupled device is attached is experiencing a cardiac arrest or failure when the heart rate reading falls outside of the heart rate threshold.

8. The method of claim 1, wherein the analyzing step further comprises audibly prompting the vehicle occupant through a human-machine interface (HMI) in response to receiving the diagnostic signal and gathering answers from the vehicle occupant to evaluate at least one of the nature or the severity of the potential medical condition.

9. The method of claim 1, wherein the analyzing step further comprises analyzing the diagnostic signal at an external object control module (EOCM) mounted within the vehicle, the external object control module (EOCM) and the vehicle system are in communication with one another via a communication bus.

10. The method of claim 1, further comprising the step:

determining if the vehicle occupant to whom the occupant-coupled device is attached is a driver of the vehicle.

11. The method of claim 10, wherein the determining step further comprises receiving a sensor signal from at least one vehicle sensor selected from the group consisting of:

an occupant detection sensor, an occupant recognition sensor, or a device detection sensor, and analyzing the sensor signal to determine if the vehicle occupant to whom the occupant-coupled device is attached is the driver of the vehicle.

12. The method of claim 11, wherein the vehicle sensor is an occupant detection sensor that indicates if an occupant is sitting in a particular seat in the vehicle, and the determining step further comprises analyzing the sensor signal from the occupant detection sensor to determine if the vehicle occupant to whom the occupant-coupled device is attached is the driver of the vehicle.

13. The method of claim 11, wherein the vehicle sensor is an occupant recognition sensor that indicates the identity of the occupant sitting in a particular seat in the vehicle, and the determining step further comprises analyzing the sensor signal from the occupant recognition sensor to determine if the vehicle occupant to whom the occupant-coupled device is attached is the driver of the vehicle.

14. The method of claim 11, wherein the vehicle sensor is a device detection sensor that indicates the presence or identity of an electronic device that is associated with a particular user, and the determining step further comprises analyzing the sensor signal from the device detection sensor to determine if the vehicle occupant to whom the occupant-coupled device is attached is the driver of the vehicle.

15. The method of claim 10, wherein the determining step further comprises audibly prompting the vehicle occupant through a human-machine interface (HMI) and gathering answers from the vehicle occupant to determine if the vehicle occupant is the driver of the vehicle.

16. The method of claim 10, wherein the determining step further comprises determining if the vehicle occupant is a driver of the vehicle at an external object control module (EOCM) mounted within the vehicle, the external object control module (EOCM), at least one vehicle sensor, and the vehicle system are in communication with one another via a communication bus.
