Abstract

There is described a system and method for establishing a performance of at least one of a vehicle and an operator of the vehicle over a given period. In particular, the method comprises: recording measured vehicle parameters at a continuous rate over a given period, the continuous rate being at least as great as the rate of change of the measured vehicle parameters; calculating criteria using, for each criterion, a selection of the measured vehicle parameters; and outputting the criteria, the criteria being representative of a performance of at least one of the operator and the vehicle over the given period.

Claims

1. A remote processing center adapted for communication with a telemetry interface device installed in a vehicle controlled by an operator, the telemetry interface device used for acquiring measurements of vehicle parameters, the remote processing center comprising:

an input communication device for receiving the measurements of vehicle parameters;

an output device;

a processor operatively connected to the input communication device and to the output device; and

a memory operatively connected to the processor and having instructions stored thereon to cause the processor;

to obtain the measurements of vehicle parameters acquired at a continuous rate over a given period, the continuous rate being at least as great as the rate of change of each of the measurements of vehicle parameters over the given period;

to calculate criteria using, for each criterion, a selection of the measurements of vehicle parameters; and

to output the criteria on the output device, the criteria being representative of a performance of at least one of the operator and the vehicle over the given period;

wherein the continuous rate and the rate of change of each of the measurements are time period-based rates having a unit of time in the numerator or denominator.

2. The remote processing center of claim 1, wherein each criterion is associated to a target and wherein the instructions further cause the processor to compare each criterion respectively to its associated target to determine a score for each criterion.

3. The remote processing center of claim 2, wherein the instructions further cause the processor to generate a driving report comprising the score for each criterion for at least one of safety and fuel economy for the vehicle.

4. The remote processing center of claim 3, wherein the remote processing center is adapted for communication with a plurality of telemetry interface devices installed in a respective vehicle of a plurality of vehicles controlled by a plurality of operators and wherein the input is for receiving the measurements of vehicle parameters from the plurality of telemetry interface devices.

5. The remote processing center of claim 4, wherein the instructions further cause the processor to generate the driving report comprising the score for each criterion for a respective vehicle of the plurality of vehicles or for a respective operator of the plurality of operators.

6. The remote processing center of claim 5, wherein the instructions further cause the processor to generate the driving report in a table format where one axis of the table is for the criteria and the other is for either the plurality of vehicles of for the plurality of operators, the table for placing the plurality of vehicles or the plurality of operators in order according to their score on a given criterion.

7. The remote processing center of claim 1, wherein the output device comprises a display for displaying the criteria.

8. The remote processing center of claim 7, wherein the vehicle parameters are geo-referenced and time-stamped, wherein the instructions further cause the processor to access and display a road map to show a mapping of the vehicle positions in time.

9. The remote processing center of claim 8, wherein the matching of a threshold by a given criterion creates an event and wherein the instructions further cause the processor to determine and display a geographical location on the road map where and the time at which the event took place.

10. A vehicle telemetry system comprising:

a telemetry interface device for installation in a vehicle controlled by an operator, the telemetry interface device for recording measurements of vehicle parameters at a continuous rate over a given period, the continuous rate being at least as great as the rate of change of each of the measurements of vehicle parameters over the given period; and

a remote processing center comprising a processor for calculating criteria using, for each criterion, a selection of the measurements of vehicle parameters and for outputting the criteria, the criteria being representative of the performance of at least one of the operator and the vehicle over the given period;

wherein the continuous rate and the rate of change of each of the measurements are time period-based rates having a unit of time in the numerator or denominator.

11. The system of claim 10, wherein the remote processing center comprises a display for displaying the criteria.

12. The system of claim 10, wherein each criterion is associated to a target and wherein the processor is further for comparing each criterion respectively to its associated target to determine a score for each criterion.

13. The system of claim 12, wherein a plurality of vehicles, controlled by a plurality of operators, are each equipped with the vehicle interface device, wherein the remote processing center receives the measurements of vehicle parameters of each one of the multiple vehicles, and further wherein the remote processing center is implemented to generate a driving report comprising the score for each criterion for a respective vehicle of the plurality of vehicles or for a respective operator of the plurality of operators.

14. A method for establishing a performance of at least one of a vehicle and an operator of the vehicle over a given period, the method comprising:

recording measurements of vehicle parameters at a continuous rate over a given period, the continuous rate being at least as great as the rate of change of each of the measurements of vehicle parameters over the given period;

calculating criteria using, for each criterion, a selection of the measurements of vehicle parameters; and

outputting the criteria, the criteria being representative of a performance of at least one of the operator and the vehicle over the given period;

wherein the continuous rate and the rate of change of each of the measurements are time period-based rates having a unit of time in the numerator or denominator.

15. The method of claim 14, wherein each criterion is associated to a target and wherein the method further comprises comparing each criterion respectively to its associated target to determine a score for each criterion.

16. The method of claim 15, further comprising generating a driving report comprising the score for each criterion for at least one of safety and fuel economy for the vehicle.

17. The method of claim 16, wherein the recording comprises recording measurements of vehicle parameters for a plurality of telemetry interface devices installed in a respective vehicle of a plurality of vehicles controlled by a plurality of operators.
