Abstract

A method and system for predictive emergency notification of a vehicle passing through a dark coverage area (DCA). The method comprises continuously monitoring at least speed and position of the vehicle; monitoring available cellular tower signal strength indicators to predict entrance into a DCA; comparing said position of the vehicle with information about boundaries of DCAs to determine whether the vehicle is about to enter the DCA; calculating a lapsed time for the vehicle to emerge from the DCA, wherein the lapsed time calculated using at least one of an entry point to the DCA, an exit point from the DCA, and an average speed of the vehicle; tracking the vehicle and the lapsed time to ensure that the vehicle is out of the DCA within the lapsed time; and notifying of a possible emergency if the vehicle has not emerged from the DCA within the lapsed time.

Claims

1. A method for predictive emergency notification of a vehicle passing through a dark coverage area (DCA), comprising:

continuously monitoring at least speed and position of the vehicle;

monitoring available cellular tower signal strength indicators to predict entrance into a DCA;

comparing said position of the vehicle with information about boundaries of DCAs to determine whether the vehicle is about to enter the DCA;

calculating a lapsed time for the vehicle to emerge from the DCA, wherein the lapsed time calculated using at least one of an entry point to the DCA, an exit point from the DCA, and an average speed of the vehicle;

tracking the vehicle and the lapsed time to ensure that the vehicle is out of the DCA within the lapsed time; and

notifying of a possible emergency if the vehicle has not emerged from the DCA within the lapsed time.

2. The method of claim 1, further comprising:

informing a driver of the vehicle of the entry of the vehicle into the DCA to provide the driver a choice of at least one of;

storing DCA entry information for later retrieval if the vehicle is later considered missing, activating a predictive emergency notification capability, and disabling the predictive emergency notification capability.

3. The method of claim 2, wherein tracking of the vehicle and notifying of the possible emergency are performed if the driver activates the predictive emergency notification.

4. The method of claim 1, further comprising:

resetting said tracking of the vehicle as the vehicle emerged from the DCA within the limitation of the lapsed time.

5. The method of claim 1, wherein the continuously monitoring of the at least speed, and the position of the vehicle is performed using a monitoring device, wherein the monitoring device is connected to an on-board diagnostic (OBD) port of the vehicle.

6. The method of claim 1, further comprising:

using a location aware device with cellular phone connectivity for continuously monitoring the at least speed and the position of the vehicle.

7. The method of claim 5, further comprising at least one of:

establishing a connection between the monitoring device and a central server via a wireless connection;

establishing a connection between the monitoring device and a global positioning system (GPS); and

establishing a connection between the monitoring device and a cellular network.

8. The method of claim 1, further comprising:

adding a lead time to the lapsed time resulting in a longer lapsed time.

9. The method of claim 7, wherein the lead time is achieved by any one of:

receiving said lead time from the driver; and

calculating said lead time as a percentage of said lapsed time.

10. The method of claim 1, wherein the lapsed time is used to prevent inadvertent possible notification.

11. A method for generating predictive emergency notification regarding a vehicle passing through a dark coverage area (DCA) comprising:

enabling a supervisor to activate a predictive emergency notification capability for tracking the vehicle;

continuously monitoring at least speed and position of the vehicle using at least a global positioning system (GPS) locator in a monitoring device installed in the vehicle;

comparing a location of the vehicle with locations of cellular towers and signal strength indicators for predicting an entry into DCA, wherein the DCA is an area without wireless coverage;

comparing the position of the vehicle with information containing the boundaries of DCAs to determine whether the vehicle is about to enter the DCA;

calculating a lapsed time for the vehicle to emerge from the DCA, wherein the lapsed time calculated using at least one of an entry point to the DCA, an exit point from the DCA, and an average speed of the vehicle;

tracking the vehicle and the lapsed time to ensure that the vehicle is out of the DCA within said lapsed time;

notifying at least one of the supervisor and a emergency analyst, of a possible emergency if the lapsed time for exit of the vehicle from the DCA is exceeded.

12. The method of claim 11, the continuously monitoring of the at least speed, and the position of the vehicle is performed using a monitoring device, wherein the monitoring device is connected to an on-board diagnostic (OBD) port of the vehicle.

13. The method of claim 11, further comprising:

using a location aware device with cellular phone connectivity for continuously monitoring the at least speed and the position of the vehicle.

14. The method claim 12, further comprising:

establishing a connection between the monitoring device and a central server via a wireless connection;

establishing a connection between said monitoring device and a global positioning system (GPS); and

establishing a connection between said monitoring device and a cellular network.

15. The method claim 13, further comprising:

establishing a connection between the location aware device and a central server via a wireless connection;

establishing a connection between the location aware device and a global positioning system (GPS); and

establishing a connection between said location aware device and a cellular network.

16. The method of claim 11, further comprising:

adding a lead time to the lapsed time resulting in a longer lapsed time.

17. The method of claim 11, wherein said lapsed time is used to prevent inadvertent possible emergency notification to at least one of the supervisor, the emergency, analyst and support agencies.

18. A system for proving notification of a possible emergency of a vehicle in a dark connection area (DCA) comprising:

a monitoring device for collecting at least position and speed information of the vehicle;

a monitoring server for receiving the collected information from the monitoring device and for performing;

predicting entry into a DCA using at least locations of cellular towers and signal strength indicators;

determining a possible entry location of the vehicle into the DCA and a possible exit location from the DCA;

calculating a lapsed time for the vehicle to emerge from the DCA, wherein the lapsed time calculated using at least one of an entry point to the DCA, an exit point from the DCA, and an average speed of the vehicle;

tracking the lapsed time and the status of the vehicle to ensure that the vehicle has exited into the WCA at the end of the lapsed time; and

emergency server for generating and sending emergency notifications in an event of the vehicle not exiting the DCA within the lapsed time.

19. The system in claim 18, wherein the monitoring device is connected to the on board diagnostic (OBD) port of the vehicle.

20. The system in claim 18, wherein the said monitoring device is a location aware device with cellular phone connectivity.
