Abstract

A method for monitoring driving behavior of a vehicle includes obtaining first information including values related to driving operations of a vehicle based on sensors and obtaining a geographical location or a vehicle type of the vehicle. The method also includes extracting second information including values related to operations of vehicles associated with the vehicle type of the vehicle or the geographical location of the vehicle and determining whether there is a difference between the first information and the second information. The method further includes instructing the vehicle to adjust driving operations in response to determining that there is the difference between the first information and the second information.

First claim

What is claimed is:

1 . A method for monitoring driving behavior of a vehicle, the method comprising:
obtaining first information including values related to driving operations of a vehicle based on sensors; obtaining a geographical location or a vehicle type of the vehicle; extracting second information including values of operations of vehicles associated with the vehicle type of the vehicle or the geographical location of the vehicle; determining whether there is a difference between the first information and the second information; and instructing the vehicle to adjust driving operations in response to determining that there is the difference between the first information and the second information, wherein: the determining of whether there is the difference between the first information and the second information is repeatedly performed at a frequency, wherein the frequency is based on a predetermined time interval, and the predetermined time interval is adjusted based on at least one of a date and a time of driving the vehicle, a type of a driver of the vehicle, criminal history of the driver of the vehicle, and the geographical location of the vehicle.

2 . The method according to claim 1 , further comprising:
in response to determining that there is the difference between the first information and the second information, transmitting a signal to the vehicle, wherein the signal instructs the vehicle to output an alert on a human-machine interface (HMI) of the vehicle, turn on a hazard light of the vehicle, brake the vehicle, limit an accelerator of the vehicle, or stop the vehicle.

3 . The method according to claim 1 , wherein the values related to driving operations of the vehicle include at least one of an acceleration pedal angle, an angular velocity, a brake pedal pressure, and a brake wheel pressure of the vehicle, and
the values of operations of the vehicles include an average acceleration pedal angle, an average angular velocity, an average brake pedal pressure, an average brake wheel pressure of the vehicles, a maximum acceleration pedal angle, a maximum angular velocity, a maximum brake pedal pressure, a maximum brake wheel pressure of the vehicles, a minimum acceleration pedal angle, a minimum angular velocity, a minimum brake pedal pressure or a minimum brake wheel pressure of the vehicles.

4 . The method according to claim 1 , further comprising:
storing the first information as abnormal driving information in response to determining that the difference between the first information and second information is greater than a threshold value.

5 . The method according to claim 1 , further comprising:
in response to determining that there is the difference between the first information and the second information, reporting to a third party.

6 . The method according to claim 1 , wherein the values of operations of the vehicles are values obtained from the vehicles located within a predetermined area which includes the geographical location of the vehicle.

7 . The method according to claim 1 , wherein the values of operations of the vehicles are values obtained from the vehicles whose types correspond to the vehicle type of the vehicle.

8 . The method according to claim 1 , wherein:
obtaining first information including values related to driving operations of the vehicle is repeatedly performed with the predetermined time interval.

9 . The method according to claim 1 wherein:
the driver type includes at least one of the driver's age, sex, and marital status.

10 . The method according to claim 1 , further comprising:
incrementing a counter based on a comparison of one or more of the values related to driving operations of the vehicle and one or more of the values of the operations of the vehicles; and determining that there is the difference between the first information and the second information in response to determining that the counter is greater than a threshold value.

11 . A system for monitoring driving behavior of a vehicle, comprising:
a controller configured to: obtain first information including values related to driving operations of a vehicle based on sensors; obtain a geographical location or a vehicle type of the vehicle; extract second information including values of operations of vehicles associated with the vehicle type of the vehicle or the geographical location of the vehicle; determine whether there is a difference between the first information and the second information; report to a third party in response to determining that there is the difference between the first information and the second information; and instruct the vehicle to adjust driving operations in response to determining that there is the difference between the first information and the second information, wherein: to determine whether there is the difference between the first information and the second information is repeatedly performed at a frequency, wherein the frequency is based on a predetermined time interval, and the predetermined time interval is adjusted based on at least one of a date and a time of driving the vehicle, a type of a driver of the vehicle, criminal history of the driver of the vehicle, and the geographical location of the vehicle.

12 . The system according to claim 11 , wherein the controller is further configured to:
in response to determining that there is the difference between the first information and the second information, transmit a signal to the vehicle, wherein the signal instructs the vehicle to output an alert on a HMI of the vehicle, turn on a hazard light of the vehicle, brake the vehicle, limit an accelerator of the vehicle, or stop the vehicle.

13 . The system according to claim 11 , wherein the values related to driving operations of the vehicle include at least one of an acceleration pedal angle, an angular velocity, a brake pedal pressure, and a brake wheel pressure of the vehicle, and
the values of operations of the vehicles include an average acceleration pedal angle, an average angular velocity, an average brake pedal pressure, an average brake wheel pressure of the vehicles, a maximum acceleration pedal angle, a maximum angular velocity, a maximum brake pedal pressure, a maximum brake wheel pressure of the vehicles, a minimum acceleration pedal angle, a minimum angular velocity, a minimum brake pedal pressure or a minimum brake wheel pressure of the vehicles.

14 . The system according to claim 11 , wherein the values of operations of the vehicles are values obtained from the vehicles located within a predetermined area which includes the geographical location of the vehicle.

15 . The system according to claim 11 , wherein the values of operations of the vehicles are values obtained from the vehicles whose types correspond to the vehicle type of the vehicle.

16 . A non-transitory computer readable medium storing instructions, when executed by a processor, causing a system to:
obtain first information including values related to driving operations of a vehicle based on sensors; obtain a geographical location or a vehicle type of the vehicle; extract second information including values of operations of vehicles associated with the vehicle type of the vehicle or the geographical location of the vehicle; determine whether there is a difference between the first information and the second information; and instruct the vehicle to adjust driving operations in response to determining that there is the difference between the first information and the second information, wherein: to
