Safe driving monitoring system
First Claim
1. A method for tracking driving habits, comprising:
- receiving an indication of an association of a personal device with a driver in a vehicle, the personal device being a telecommunications and computing device associated with a driver of the vehicle;
determining that the driver is engaging in a suspect activity while driving;
comparing the suspect activity with a severity scale indicative of a relative risk of the activity, comparing further comprising;
determining a metric associated with the suspect activity;
computing a first driving parameter associated with the determined metric;
comparing the driving parameter to a statistical distribution, including a Cauchy distribution translated by a second driving parameter, of events of other drivers for the first driving parameter, the first driving parameter being a scalar quantity pertaining to vehicle motion and the second driving parameter based on ambient conditions; and
concluding a high severity if the driving parameter is outside a predetermined range of the Cauchy distribution;
computing a score based on the comparison; and
reporting the determined suspect activity and the score to a repository for accumulating a renderable driving history of the driver indicative of distracted driving events.

Abstract
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.

17. A method for tracking driving events, comprising:
-
determining, via a personal device associated with a driver in a vehicle, a speed of the vehicle based on a computed positioning of the personal device; receiving a user defined speed threshold corresponding to a road type determined from the position of the vehicle, the threshold defined for the road type, the personal device being a telecommunications and computing device associated with a driver of the vehicle; receiving a location indication of the personal device; receiving a location indication of a positioning device; comparing the received location indications to conclude driver presence in the vehicle; and comparing a first driving parameter indicative of the speed to the received threshold and reporting the determined speed and the road type if the determined speed exceeds the threshold corresponding to the road type currently being traveled for rendering a driving history of the driver indicative of distracted driving events, comparing further comprising; comparing the driving parameter to a statistical distribution, including a Cauchy distribution translated by a second driving parameter, of events of other drivers for the first driving parameter, the first driving parameter being a scalar quantity pertaining to vehicle motion and the second driving parameter based on ambient conditions including the road type; concluding a high severity if the driving parameter is outside a predetermined range of the Cauchy distribution; computing a score based on the comparison; and reporting the determined suspect activity and the score to a repository for accumulating a renderable driving history of the driver indicative of distracted driving events. - View Dependent Claims (18, 19, 20)
