Abstract

The invention provides a system for analyzing and evaluating the performance and behavior of a driver of a vehicle, and for displaying the results of the analysis and evaluation. A vehicle sensor utility is used to monitor the state of the vehicle while being driven by the driver. A raw data stream from the vehicle sensor utility is input to a driving event handler that detects driving events in the raw data stream and outputs to a maneuver detector a driving event string. The maneuver detector is configured to recognize patterns of driving maneuvers. One or more ratings of the driver'"'"'s driving performance are calculated based upon the driving maneuvers as executed by the driver. The ratings are displayed on a display.

Claims

1. A system for displaying real time evaluations of driving sessions to a driver , the system comprising:

(a) a vehicle sensor utility operative to monitor the state of the vehicle and to output a raw data stream corresponding thereto;

(b) a driving event handler operative to receive the raw data stream, to detect driving events based thereon and to output a driving event string containing at least one driving event representation corresponding thereto;

(c) a maneuver detector operative to receive said at least one driving event representation, recognize patterns of driving maneuvers and to construct and output a driving maneuver representation corresponding thereto, said driving maneuver representation containing a representation of at least one driving maneuver;

(d) a processor configured to evaluate a driving session based upon rating each of a plurality of driving maneuvers comprised in said driving session and to display the evaluation of said driving session and/or the rating of said plurality of driving maneuvers on a display; and

(e) a display.

2. The system of claim 1, wherein said driving session is categorized into a number of driving categories and the category of each driving session is determined by the number and rate of the plurality of driving maneuvers comprised in said driving session.

3. The system of claim 1, wherein said system is further adapted to display one or more major risk maneuvers from among said plurality of driving maneuvers in said driving session.

4. The system of claim 1, further comprising a database for storing characteristic records of driving maneuvers associated with at least one driver, and means for comparing a stored characteristic driving maneuver with a driving maneuver representation of a maneuver currently being carried out by said driver, and for providing an indication to said driver if an anomaly is detected from the stored characteristic driving maneuver.

5. A method for displaying real time evaluations of driving sessions to a driver which comprises the steps of:

(a) monitoring the state of the vehicle and outputting a raw data stream corresponding thereto;

(b) receiving the raw data stream, detecting driving events based on said raw data stream and outputting a driving event string containing at least one driving event representation corresponding to the detected driving event;

(c) deriving from said at least one driving event representation patterns of driving maneuvers and constructing and outputting a driving maneuver representation corresponding thereto, said driving maneuver representation containing a representation of at least one driving maneuver; and

(d) evaluating a driving session based upon rating of each of a plurality of driving maneuvers comprised in said driving session; and

(e) displaying the evaluation of said driving session and/or rating of said plurality of driving maneuvers on a display.

6. The method of claim 5, wherein said driving session is categorized into a number of driving categories and the category of each driving session is determined by the number and rate of the plurality of driving maneuvers comprised in said driving session.

7. The method of claim 5, further comprising displaying one or more major risk maneuvers from among said plurality of driving maneuvers in said driving session.

8. The method of claim 5, further comprising a step of storing characteristic records of driving maneuvers associated with at least one driver, comparing a stored characteristic driving maneuver with a driving maneuver representation of a maneuver currently being carried out by said driver, and providing an indication to said driver if an anomaly is detected from the stored characteristic driving maneuver.

9. A computer program product comprising a computer useable medium having computer readable program code embodied therein for displaying real time evaluations of driving sessions to a driver, comprising:

(a) monitoring the state of the vehicle and outputting a raw data stream corresponding thereto;

(b) receiving the raw data stream, detecting driving events based on said raw data stream and outputting a driving event string containing at least one driving event representation corresponding to the detected driving event;

(c) deriving from said at least one driving event representation patterns of driving maneuvers and constructing and outputting a driving maneuver representation corresponding thereto, said driving maneuver representation containing a representation of at least one driving maneuver;

(d) evaluating a driving session based upon rating of each of a plurality of driving maneuvers comprised in said driving session; and

(e) displaying the evaluation of said driving session and/or rating thereof.
