Abstract

A method for notifying parties in close proximity to a vehicle of a potential vehicle hazard includes detecting that the vehicle has been in a collision, determining the type of propulsion system used by the vehicle, generating a warning or other notification relating to the propulsion system, and communicating the notification to a party located within a predetermined range of the vehicle. Communication of the notification can be carried out by renaming the telematics unit with a device name corresponding to a hazard associated with the propulsion system, and then broadcasting the device name according to an established wireless protocol.

Claims

1. A method of notifying parties in close proximity to a vehicle of a potential vehicle hazard, comprising the steps of:

(a) identifying an abnormal condition of a vehicle;

(b) generating a notification that identifies at least one possible hazard relating to a propulsion system used by the vehicle; and

(c) communicating the notification to a party located within a predetermined range of the vehicle.

2. The method of claim 1, wherein step (c) further comprises presenting the notification on an electronic display located on the vehicle.

3. The method of claim 1, wherein step (c) further comprises the steps of:

accessing an audible recording of the notification; and

broadcasting the recording via a speaker located on the vehicle.

4. The method of claim 1, wherein step (b) further comprises accessing a vehicle identification number (VIN) stored on the vehicle, wherein the VIN includes a propulsion system identifier, and generating the notification based on the propulsion system identifier.

5. The method of claim 1, wherein the propulsion system of the vehicle comprises a fuel-cell propulsion system, a hybrid-electric propulsion system, or a high-voltage battery propulsion system.

6. The method of claim 1, wherein step (b) further comprises configuring an on-board vehicle telematics unit with a name that identifies the hazard, and wherein step (c) further comprises supplying the name wirelessly to nearby portable communication devices.

7. The method of claim 6, wherein the name comprises a wireless device name for the telematics unit or a wireless network name broadcasted by the telematics unit.

8. The method of claim 1, wherein step (a) further comprises the step of detecting a propulsion system failure or a collision event.

9. A method of notifying parties in close proximity to a vehicle of a potential vehicle hazard, comprising the steps of:

(a) including a propulsion system identifier with a vehicle identification number (VIN);

(b) detecting that the vehicle is disabled;

(c) accessing the propulsion system identifier to determine the type of propulsion system installed on the vehicle;

(d) determining at least one hazard posed in the immediate area of the vehicle relating to the propulsion system; and

(e) wirelessly communicating a notification concerning the hazard using a vehicle telematics unit to at least one device able to receive short-range wireless communications.

10. The method of claim 9, further comprising the step of activating an exterior vehicle light that produces periodic flashes of light.

11. The method of claim 9, further comprising the step of presenting the one or more hazard on an electronic display located on the vehicle.

12. The method of claim 9, further comprising the steps of:

accessing an audible recording of the notification; and

broadcasting the recording via a speaker located on the vehicle.

13. The method of claim 9, wherein the propulsion system of the vehicle comprises a fuel-cell propulsion system, a hybrid-electric propulsion system, or a high-voltage battery propulsion system.

14. The method of claim 9, wherein step (e) further comprises the steps of:

configuring the telematics unit with a name that corresponds to at least one identified hazard; and

supplying the name to the device via the short-range communications.

15. A method of notifying parties in close proximity to a vehicle of a potential vehicle hazard, comprising the steps of:

(a) detecting that a vehicle has been involved in a collision, the vehicle being equipped with a telematics unit configured for short-range wireless communication via an established protocol that enables broadcasting of a device name for the telematics unit;

(b) configuring the telematics unit with a name relating to the type of propulsion system used by the vehicle;

(c) activating the short-range wireless communication using the established protocol; and

(d) broadcasting the name via the short-range communication.

16. The method of claim 15, wherein step (b) further comprises the steps of:

accessing a vehicle identification number (VIN) stored on the vehicle;

retrieving a propulsion system identifier from the VIN; and

configuring the telematics unit with a name that corresponds to the propulsion system identifier.

17. The method of claim 15, further comprising the steps of:

accessing an audible recording relating to the type of propulsions system; and

broadcasting the recording via a speaker located on the vehicle.

18. The method of claim 15, wherein the name comprises a wireless device name for the telematics unit or a wireless network name broadcasted by the telematics unit.

19. The method of claim 15, wherein the propulsion system of the vehicle comprises a fuel cell propulsion system, a hybrid-electric propulsion system, or a high-voltage battery propulsion system.

20. The method of claim 15, wherein a fuel used by the propulsion system comprises ethanol, compressed natural gas, hydrogen, diesel, or gasoline.
