Safe driving monitoring system
A method and system for detecting unsafe or suspect activities such as distracted driving associates distracted driving events to the road type, vehicle speed and vehicle acceleration (positive, negative and lateral) at the time of the distracted driving event, and identifies severe distracted driving events from a large population of minor events using a statistical distribution such as a Cauchy distribution equation. The system employs a smartphone application (App) coupled with a central server that computes driver safety scores which relate time of day, road type, vehicle speed, vehicle acceleration (positive, negative and lateral) and distracted driving using the Cauchy distribution equation. The server renders summary and detail reports of driving scores and distracted driving events to concerned parties including insurance companies, fleet managers, vehicle owners and the parents/guardians of teenaged drivers.
1. A method of detecting distracted driving, comprising:
detecting suspect activity associated with a vehicle driver based at least in part on mobile device use data collected by a mobile device associated with the vehicle driver;
generating a suspect activity record comprising mobile device use data associated with the detected suspect activity; and
providing the suspect activity record and an identifier of the vehicle driver to a repository.
2. The method of claim 1 , wherein detecting the suspect activity includes determining applications running on the mobile device.
3. The method of claim 1 , wherein detecting the suspect activity includes detecting that the mobile device is being unlocked.
4. The method of claim 1 , wherein detecting the suspect activity includes detecting movement of the mobile device; and determining that the mobile device is in use based on the movement.
5. The method of claim 4 , wherein the movement includes at least one of typing on the mobile device and moving the mobile device to a driver's ear.
6. The method of claim 1 , wherein detecting the suspect activity includes measuring data being sent to and from the mobile device and detecting use of the mobile device when the data exceeds a predetermined amount.
7. The method of claim 1 , wherein the mobile device is associated with the vehicle driver by:
determining that the mobile device is located at a driver position in a vehicle; and
associating the mobile device with the vehicle driver based at least in part on the determination.
8. The method of claim 1 , wherein the suspect activity record further comprises driving parameters associated with the detected suspect activity.
9. The method of claim 8 , wherein the driving parameters include scalar quantities indicative of vehicle motion and ambient conditions in which the vehicle is operating, and the suspect activity includes at least one of the driving parameters exceeding a threshold and usage of the mobile device.
10. The method of claim 1 , further comprising:
generating a score based at least in part on the mobile device use data associated with the detected suspect activity.
11. The method of claim 10 , wherein generating the score comprises:
comparing driving parameters to a severity scale indicative of a relative risk associated with the suspect activity; and
generating the score based at least in part on the comparison.
12. The method of claim 1 , wherein use of the mobile device comprises one or more of texting, internet browsing, voice communication, and application invocation.
13. The method of claim 1 , wherein detecting the suspect activity comprises determining that one or more driving parameters exceeds a threshold value.
14. The method of claim 1 , wherein the repository is associated with one or more of a telematics platform, an insurance provider, and a government agency.
15. The method of claim 1 , wherein the suspect activity record is stored in a driving history of the vehicle driver at the repository.
16. The method of claim 1 , wherein the suspect activity record and the identifier of the vehicle driver are provided to the repository via a telematics appliance affixed to the vehicle.
17. The method of claim 16 , wherein the mobile device and telematics appliance communicate using one or more of Bluetooth, Bluetooth Low Energy, WiFi, near field communications (NFC), and transmissions under IEEE 802.11.
18. A method of detecting distracted driving, comprising:
detecting suspect activity associated with a vehicle driver based at least in part on use of a mobile device associated with the vehicle driver;
generating a suspect activity record comprising mobile device use data and driving parameters associated with the detected suspect activity;
providing the suspect activity record and an identifier of the vehicle driver to a repository; and
generating a score based at least in part on the mobile device use data and the driving parameters associated with the detected suspect activity, wherein the score is generated based at least in part on a comparison of the driving parameters and mobile device use data to a severity scale indicative of a relative risk associated with the suspect activity.
