SAFE DRIVING MONITORING SYSTEM

摘要

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.

主权项

1. A method for tracking driving activity, comprising:
associating a personal device with a driver in a vehicle by establishing a driver presence in an operator position in the vehicle; receiving driving parameters indicative of vehicle operation; and transmitting the received driving parameters to a server for determining if the associated driver is engaging in a suspect activity while driving the vehicle by performing a Cauchy distribution for comparing the received driving parameters denoting the suspect activity with a severity scale indicative of a relative risk of the suspect activity, the relative risk based on values derived from driving parameters of other drivers; the server further operable for: accumulating the gathered parameters for computing a score of the driver based on the comparison; concluding that a suspect activity is occurring based on the computed score; and reporting the determined suspect activity and the score to a repository for accumulating a driving history of the driver.
