Abstract

A method and system are provided for evaluating driving performance of a driver according to one or more of at least two different performance classes, wherein each performance class relates to a different aspect of driving performance than the others. The method comprising the steps of: identifying a plurality of driving events in a driving session, wherein each of the driving events is associated with indicators characterizing the respective driving event; retrieving values for indicators associated with the respective driving events identified; providing a plurality of pre-defined coefficients that enable adapting the retrieved indicators'"'"' values to one of the at least two different performance classes; and based on the values retrieved for the indicators associated with the identified driving events and the plurality of pre-defined coefficients, evaluating a driving performance that is compatible with one or more of the at least two different performance classes.

Claims

1. A method for evaluating driving performance of a driver according to one or more of at least two different performance classes, wherein each performance class relates to a different aspect of driving performance than the others, said method comprising:

identifying a plurality of driving events in one or more driving sessions, wherein each of the driving events is associated with one or more indicators characterizing the respective driving event;

retrieving values for indicators associated with the respective driving events identified;

providing a plurality of pre-defined coefficients that enable adapting the retrieved indicators'"'"' values to one of the at least two different performance classes; and

based on the values retrieved for the indicators associated with the identified driving events and the plurality of pre-defined coefficients, evaluating a driving performance that is compatible with one or more of said at least two different performance classes.

2. The method according to claim 1, wherein the pre-defined coefficients are operative to adapt the retrieved indicators'"'"' values to one of the at least two different performance classes, based upon the significance of the type of a driving event associated with the indicators being adapted, to the respective driving performance class.

3. The method according to claim 1, further comprising a step of dividing the indicators and/or the values thereof into groups, wherein at least one of these groups contains only one or more indicators and/or their values that are associated with one type of the identified driving events, and deriving a representative value for each of the indicators associated with the at least one group, wherein each representative value is derived based on the values of respective indicators included in that at least one group.

4. The method according to claim 1, wherein each of the at least two different classes of driving performance is associated with a corresponding set of a plurality of pre-defined coefficients.

5. The method according to claim 1, wherein one of the at least two different performance classes is safety and another one of the at least two different performance classes is economical driving.

6. The method according to claim 1, wherein the driving performance of the driver is an overall driving performance which is evaluated according to two or more different performance classes.

7. The method according to claim 6, wherein each of the two or more different performance classes is associated with a coefficient relative to the significance of that performance in the evaluation of the driver'"'"'s overall driving performance.

8. The method according to claim 1, wherein the driving performance of the driver is evaluated for a pre-determined period of time.

9. The method according to claim 1, wherein the driving performance of the driver is evaluated for a pre-determined road section.

10. The method according to claim 1, wherein the value of at least one of the plurality of the pre-determined coefficients is affected by the specific vehicle being driven by the driver.

11. The method according to claim 1, wherein at least some of the plurality of pre-determined coefficients are associated with more than one value, and the value to be used is selected based upon at least one external factor which is not dependent on the driver'"'"'s driving performance.

12. The method according to claim 1, wherein the step of retrieving values for indicators associated with the respective driving events identified, further comprises retrieving values for indicators that are associated with the one or more driving sessions but are not associated with any of the identified driving events.

13. A system for evaluating driving performance of a driver according to one or more of at least two different performance classes, wherein each performance class relates to a different aspect of driving performance than the others, said system comprising:

a plurality of sensors located within a vehicle being driven by the driver, operative to collect data that relates to the performance of a driver during one or more driving sessions; and

a processor adapted to;

identify a plurality of driving events in one or more driving sessions from among the data collected, wherein each of the driving events is associated with one or more indicators characterizing the respective driving event, and wherein the plurality of driving events identified comprises driving events of at least two different types;

based on the data collected by one or more of the plurality of sensors, retrieve values for indicators associated with each of the respective driving events identified;

based on the values retrieved for the indicators associated with the identified driving events, and a plurality of pre-defined coefficients used for adapting said retrieved indicators'"'"' values to one of the at least two different performance classes, evaluate a driving performance that is compatible with one or more of said at least two different performance classes.

14. The system according to claim 13, wherein said processor is configured to apply the pre-defined coefficients in order to adapt the retrieved indicators'"'"' values to one of the at least two different performance classes, based upon the significance of the type of the driving event associated with the indicators being adapted, to the respective driving performance class.

15. The system according to claim 13, wherein said processor is further configured to divide the indicators and/or the values thereof into groups, wherein at least one of these groups contains only one or more indicators and/or their values associated with one type of the identified driving events, and to derive therefrom a representative value for each of the indicators associated with the at least one group, wherein each representative value is derived based on the values of respective indicators included in that at least one group.

16. The system according to claim 13, wherein each of the at least two different classes of driving performance is associated with a corresponding set of a plurality of pre-defined coefficients.

17. The system according to claim 13, wherein the driving performance of the driver is an overall driving performance which is evaluated according to two or more different performance classes.

18. A computer program product encoding a computer program stored on a non-transitory computer readable storage medium for executing a set of instructions by a computer system comprising one or more computer processors for carrying out a method for evaluating a driving performance of a driver according to one or more of at least two different performance classes, wherein each performance class relates to a different aspect of driving performance than the others, the method comprising:

identifying a plurality of driving events in one or more driving sessions, wherein each of the driving events is associated with one or more indicators characterizing the respective driving event, and wherein the plurality of driving events identified comprises driving events of at least two different types;
