Abstract

The disclosure includes implementations for providing a personalized medical emergency autopilot system based on data from a portable medical device. A method may include receiving, by a communication unit of a vehicle, a wireless message from a wireless network. The wireless message includes sensor data describing one or more current physiological signals of a driver of the vehicle that are recorded by a portable medical device worn by the driver. The method may include analyzing the one or more current physiological signals of the driver to identify a medical emergency for the driver. The method may include overriding, by a personalized medical emergency autopilot system, one or more vehicle control inputs provided by the driver subsequent to identifying the medical emergency so that the driver cannot control the operation of the vehicle during the medical emergency.

Claims

1. A system comprising:

a vehicle communicatively coupled to a portable medical device of a driver via a wireless network;

wherein the vehicle includes an Advanced Driver Assistance System (“

ADAS system”

);

wherein the ADAS system includes a personalized medical emergency autopilot system that is operable to receive sensor data of the driver via the wireless network, wherein the sensor data describes one or more current physiological signals describing the driver as recorded by one or more physiological sensors included in the portable medical device of the driver;

wherein the personalized medical emergency autopilot system is operable to analyze the one or more current physiological signals of the driver to identify a medical emergency for the driver;

wherein the personalized medical emergency autopilot system is operable to retrieve a remedial action plan and identify a response that is customized for the medical emergency for the driver; and

wherein the personalized medical emergency autopilot system is operable to respond based on the remedial action plan by overriding one or more vehicle control inputs provided by the driver subsequent to identifying the medical emergency so that the driver cannot control the operation of the vehicle during the medical emergency.

2. The system of claim 1, wherein analyzing the one or more current physiological signals of the driver to identify the medical emergency for the driver includes analyzing the sensor data based on a user profile that describes expected physiological signals for the driver based on a medical history of the driver.

3. The system of claim 1, wherein the response includes autonomously driving the vehicle to a specified location.

4. The system of claim 3, wherein the specified location is a medical facility and the response further includes wirelessly communicating with the medical facility via the wireless network to provide the medical facility with a wireless message that identifies the driver and the medical emergency.

5. The system of claim 4, wherein the wireless message further identifies one or more of an estimated time of arrival for the vehicle at the medical facility and a current geographic location of the vehicle.

6. The system of claim 3, wherein the specified location is parking location.

7. The system of claim 6, wherein the parking location includes one or more of a parking spot or a location in a breakdown lane.

8. The system of claim 6, wherein the response further includes wirelessly communicating with an emergency responder via the wireless network to provide the emergency responder with a wireless message that identifies the driver, the medical emergency and a geographic location of the parking location.

9. The system of claim 8, wherein the geographic location is accurate to within plus or minus substantially three meters.

10. A method comprising:

receiving, by a communication unit of a vehicle, a wireless message from a wireless network, wherein the wireless message includes sensor data describing one or more current physiological signals of a driver of the vehicle that are recorded by a portable medical device worn by the driver;

analyzing the one or more current physiological signals of the driver to identify a medical emergency for the driver;

identifying a response based on a remedial action plan that is customized for the medical emergency for the driver; and

overriding, by a personalized medical emergency autopilot system, based on the remedial action plan, one or more vehicle control inputs provided by the driver subsequent to identifying the medical emergency so that the driver cannot control the operation of the vehicle during the medical emergency.

11. The method of claim 10, wherein the one or more vehicle control inputs include steering the vehicle.

12. The method of claim 10, wherein the one or more vehicle control inputs include accelerating the vehicle.

13. The method of claim 10, wherein the one or more vehicle control inputs include braking the vehicle.

14. The method of claim 10, wherein overriding the one or more vehicle control inputs provided by the driver includes assigning a highest priority to one or more vehicle control inputs provided by an ADAS system of the vehicle so that the ADAS system may control the operation of the vehicle and the driver cannot control the operation of the vehicle.

15. The method of claim 10, wherein the wireless message is received via a secured communication channel and the method further comprises decrypting the wireless message.

16. The method of claim 10, wherein the sensor data is incorporated into an ADAS system of the vehicle so that the ADAS system has access to physiological signals of the driver.

17. A computer program product of a vehicle comprising a non-transitory memory storing computer-executable code that, when executed by a processor of the vehicle, causes the processor to:

receive a wireless message from a wireless network, wherein the wireless message includes sensor data describing one or more current physiological signals of a driver of the vehicle that are recorded by a portable medical device worn by the driver;

analyze the one or more current physiological signals of the driver to identify a medical emergency for the driver;

identify a response based on a remedial action plan that is customized for the medical emergency for the driver; and

override, based on the remedial action plan, one or more vehicle control inputs provided by the driver subsequent to identifying the medical emergency so that the driver cannot control the operation of the vehicle during the medical emergency.

18. The computer program product of claim 17, wherein the wireless message is transmitted to the wireless network by the portable medical device.

19. The computer program product of claim 17, wherein the wireless message is received in substantially real time relative to when the one or more current physiological signals are recorded by the portable medical device.

20. The computer program product of claim 17, wherein the one or more current physiological signals are directly recorded by the portable medical device and not inferred by the vehicle or the portable medical device.
