Abstract

Systems and methods are provided for programmatically verifying an origin of abnormal driving. Some examples of abnormal driving may include aggressive driving (e.g., tailgating, cut-in lane, etc.), distracted driving (e.g., swerving, delayed reaction, etc.), and reckless driving (e.g., green light running, lane change without signaling, etc.). For example, the systems and methods may receive an identification of a second vehicle performing abnormal driving from an ego vehicle; initiate a verification process of the identification of the abnormal driving; access driving data associated with an origin of the abnormal driving, wherein the driving data includes the ego vehicle and the second vehicle; using the driving data, determine a confirm or deny decision regarding the identification of the second vehicle from the ego vehicle; and provide the confirm or deny decision.

Claims (37)

1 . A system for verifying an identification of abnormal driving performed by a subject vehicle, the system comprising:

a memory; and

one or more processors that are configured to execute machine readable instructions stored in the memory to:

determine abnormal driving performed by the subject vehicle for a current environmental condition, wherein the determination is based on past identifications of abnormal driving from other vehicles at a lane of the subject vehicle, and further wherein the past identifications are determined in association with corresponding environmental conditions at a time of such identifications;

initiate a verification process of the identification of the abnormal driving performed by the subject vehicle;

access driving data associated with an origin of the abnormal driving, wherein the driving data includes driving data of an ego vehicle and the subject vehicle;

using the driving data, confirm whether the abnormal driving by the subject vehicle is occurring;

based on the confirmation, wirelessly transmit identification information regarding the identification of abnormal driving performed by the subject vehicle to the ego vehicle; and

modify an operation of an advanced-driver assistance system (ADAS) of the ego vehicle to execute an ADAS maneuver with the ego vehicle based on the confirmation.

2 . The system of claim 1 , wherein the driving data associated with the origin of the abnormal driving is received from a section manager or a locality manager where the ego vehicle or the subject vehicle travels.

3 . The system of claim 1 , wherein the ego vehicle generates the identification of the subject vehicle using a trained machine learning model generated and trained by the anomaly managing system.

4 . The system of claim 1 , wherein the ego vehicle generates the identification of the subject vehicle using a time series analysis or pattern matching generated by the anomaly managing system.

5 . The system of claim 1 , wherein the driving data includes a geographic location of the subject vehicle.

6 . The system of claim 1 , wherein the origin is determined by retracing operations performed by the subject vehicle by stepping back in time to uncover a root-cause of the abnormal driving performed by the subject vehicle.

7 . The system of claim 1 , wherein the origin is determined by comparing operations performed by the subject vehicle with regional or local driving behavior.

8 . The system of claim 1 , wherein the origin is determined by identifying reoccurring and repeated abnormal driving behavior that has been previously reported.

9 . The anomaly managing system of claim 1 , wherein the confirmation is provided to the ego vehicle, the instructions further to:

request feedback from a driver of the ego vehicle or subject vehicle to acknowledge the confirmation.

10 . The system of claim 1 , wherein the confirmation is provided to the ego vehicle, the instructions further to:

distribute identification of the subject vehicle to other vehicles.

11 . The system of claim 1 , wherein the confirmation is provided to a human operator.

12 . A non-transitory machine-readable medium associated with a system having instructions stored therein, which when executed by a processor, cause the processor to perform operations, the operations comprising:

determining abnormal driving performed by a subject vehicle for a current environmental condition, wherein the determination is based on past identifications of abnormal driving from other vehicles at a lane of the subject vehicle, and further wherein the past identifications are determined in association with corresponding environmental conditions at a time of such identifications;

initiating a verification process of the identification of the abnormal driving performed by the subject vehicle;

accessing driving data associated with an origin of the abnormal driving, wherein the driving data includes driving data of at least one of the other vehicles and the subject vehicle;

using the driving data, confirm whether the abnormal driving by the subject vehicle is occurring;

based on the confirmation, wirelessly transmitting identification information regarding the identification of abnormal driving performed by the subject vehicle to the other vehicles; and

modifying an operation of an advanced-driver assistance system (ADAS) of the other vehicles to execute an ADAS maneuver with the other vehicles based on the confirmation.

13 . The non-transitory machine-readable medium of claim 12 , wherein the driving data associated with the origin of the abnormal driving is received from a section manager or a locality manager where the subject vehicle travels.

14 . The non-transitory machine-readable medium of claim 12 , wherein an ego vehicle generates the identification of the subject vehicle using a trained machine learning model generated and trained by the anomaly managing system.

15 . The non-transitory machine-readable medium of claim 12 , wherein an ego vehicle generates the identification of the subject vehicle using a time series analysis or pattern matching generated by the anomaly managing system.

16 . The non-transitory machine-readable medium of claim 12 , wherein the driving data includes a geographic location of the subject vehicle.

17 . The non-transitory machine-readable medium of claim 12 , wherein the origin is determined by retracing operations performed by the subject vehicle by stepping back in time to uncover a root-cause of the abnormal driving performed by the subject vehicle.

18 . The non-transitory machine-readable medium of claim 12 , wherein the origin is determined by comparing operations performed by the subject vehicle with regional or local driving behavior.

19 . The non-transitory machine-readable medium of claim 12 , wherein the origin is determined by identifying reoccurring and repeated abnormal driving behavior that has been previously reported.

20 . The non-transitory machine-readable medium of claim 12 , wherein the confirmation is provided to the subject vehicle, and wherein the operations further comprising:

requesting feedback from a driver or subject vehicle to acknowledge the confirmation.
