Abstract

A method, a system, and a computer program product for generating emergency event notification data are disclosed herein. The method, for example, comprises determining an emergency event, based on first sensor data. The method further includes determining vehicle behavior of a first vehicle, based on the determined emergency event and generating the emergency event notification data corresponding to the emergency event, based on the determined vehicle behavior. The method may further include transmitting at least one emergency event notification to at least one recipient, based on the generated emergency event notification data.

First claim

We claim:

1. A method for generating emergency event notification data, the method comprising:
determining, by a processor, an occurrence of an emergency event based on first sensor data;
determining, in real-time, vehicle behavior of a first vehicle involved in the emergency event, wherein the vehicle behavior includes changes in speed data and lane data; and
generating the emergency event notification data corresponding to the determined emergency event, based on the determined vehicle behavior.

2. The method of claim 1 , further comprising:
obtaining the first sensor data from at least one of the first vehicle or a second vehicle, wherein one of the first vehicle or the first vehicle and the second vehicle is associated with the determined emergency event.

3. The method of claim 2 , wherein determining the vehicle behavior of the first vehicle comprises:
obtaining second sensor data from at least one of the first vehicle, the second vehicle, or an external source, based on the determined emergency event; and
determining the vehicle behavior of the first vehicle, based on the first and second sensor data.

4. The method of claim 1 , further comprising:
obtaining third sensor data associated with the determined emergency event; and
generating the emergency event notification data corresponding to the determined emergency event, based on the third sensor data.

5. The method of claim 1 , wherein determining a validity of the vehicle behavior of the first vehicle comprises:
determining the change in speed data of the first vehicle over a first time period;
comparing the change in speed data with a pre-determined speed threshold;
determining a deceleration or a stopping action by the first vehicle based on the change in speed data being less than zero;
determining an acceleration by the first vehicle based on the change in speed data being greater than zero; and
generating the emergency event notification based on the determination.

6. The method of claim 1 , wherein determining a validity of the vehicle behavior of the first vehicle comprises:
determining the change in lane data of the first vehicle over a second time period based on position data of the first vehicle;
determining a deceleration or a stopping action by the first vehicle based on movement of the first vehicle from a fast lane to a slow lane;
determining an acceleration by the first vehicle based on movement of the first vehicle from the slow lane to the fast lane; and
generating the emergency event notification based on the determination.

7. The method of claim 1 , wherein determining a validity of the vehicle behavior of the first vehicle comprises:
determining a change in location data of the first vehicle over a third time period, wherein the location data includes position data, speed data, road attributes, or a combination thereof; and
generating the emergency event notification based on the determination.

8. The method of claim 1 , wherein determining a validity of the vehicle behavior of the first vehicle comprises:
determining position data of the first vehicle and traffic signal data over a fourth time period;
comparing the position data of the first vehicle with the traffic signal data to determine whether the first vehicle jumped the traffic signal; and
generating the emergency event notification data based on the determination.

9. The method of claim 1 , further comprising:
determining fitness status associated with the determined emergency event, wherein the generation of the emergency event notification data is further based on the determined fitness status.

10. The method of claim 1 , further comprising:
determining driving mode information of the first vehicle involved in the emergency event, wherein the driving mode information includes an autonomous mode or a non-autonomous mode.

11. A system for generating emergency event notification data, the system comprising:
at least one memory configured to store computer program code instructions; and
at least one processor configured to execute the computer program code instructions to:
determine an occurrence of an emergency event, based on first sensor data;
determine, in real-time, vehicle behavior of a first vehicle involved in the emergency event, wherein the vehicle behavior includes changes in position data of the first vehicle relative to a traffic signal; and
generate the emergency event notification data corresponding to the determined emergency event, based on the determined vehicle behavior.

12. The system of claim 11 , wherein the at least one processor is further configured to:
obtain the first sensor data from at least one of the first vehicle or a second vehicle, wherein one of the first vehicle or the first vehicle and the second vehicle is associated with the determined emergency event.

13. The system of claim 12 , wherein to determine the vehicle behavior of the first vehicle, the at least one processor is further configured to:
obtain second sensor data from at least one of the first vehicle, the second vehicle, or an external source, based on the determined emergency event; and
determine the vehicle behavior of the first vehicle, based on the second sensor data.

14. The system of claim 11 , wherein the at least one processor is further configured to:
obtain third sensor data associated with the determined emergency event; and
generate the emergency event notification data corresponding to the emergency event, based on the third sensor data.

15. The system of claim 11 , wherein to determine a validity of the vehicle behavior of the first vehicle, the at least one processor is configured to:
determine a change in speed data of the first vehicle over a first time period;
compare the change in speed data with a pre-determined speed threshold;
determine a deceleration or a stopping action by the first vehicle based on the change in speed data being less than zero;
determine an acceleration by the first vehicle based on the change in speed data being greater than zero; and
generate the emergency event notification based on the determination.

16. The system of claim 11 , wherein to determine a validity of the vehicle behavior of the first vehicle, the at least one processor is configured to:
determine a change in lane data of the first vehicle over a second time period based on position data of the first vehicle;
determine a deceleration or a stopping action by the first vehicle based on movement of the first vehicle from a fast lane to a slow lane;
determine an acceleration by the first vehicle based on movement of the first vehicle from the slow lane to the fast lane; and
generate the emergency event notification based on the determination.

17. The system of claim 11 , wherein to determine a validity of the vehicle behavior of the first vehicle, the at least one processor is configured to:
determine a change in location data of the first vehicle over a third time period, wherein the location data includes position data, speed data, road attributes, or a combination thereof; and
generate the emergency event notification data based on the determination.

18. The system of claim 11 , wherein to determine a validity of the vehicle behavior of the first vehicle, the at least one processor is configured to:
determine the position data of the first vehicle and traffic signal data over a fourth time period;
compare the position data of the first vehicle with the traffic signal data to determine whether the first vehicle jumped the traffic signal; a
