Abstract

A computer implemented process is carried out by identifying a metric that characterizes an event associated with the operation of an industrial vehicle. Information about the metric is transmitted to an industrial vehicle. Further, the process includes receiving event data that characterizes a response of the industrial vehicle to the event. The process also includes updating a score for the instance of the metric associated with the vehicle operator by deriving a raw score value based upon the received event data, aggregating the derived raw score value to previously derived raw scores for the metric, and computing a modified score by applying a filter to the aggregate of raw score values. The process also includes comparing the computed modified score with a predetermined modification criteria, and sending a command back to the industrial vehicle to modify the industrial vehicle based upon the comparison.

First claim

What is claimed is:

1. A computer implemented process of controlling industrial vehicle performance, comprising:
identifying, at a server computer, a metric that characterizes an event associated with the operation of an industrial vehicle, the metric having at least one performance parameter to evaluate against the event, wherein the performance parameter indicates a desired performance that correlates to correct operation of the industrial vehicle and is used to enable a feature on the industrial vehicle;
associating the metric with an industrial vehicle operator login identification;
transmitting information about the metric to the industrial vehicle to which an operator has logged in with the industrial vehicle operator login identification, wherein the information about the metric triggers specific programming within the industrial vehicle to begin processing the received information about the metric against monitored industrial vehicle operational information that is collected by the industrial vehicle during use thereof; and
performing in an ongoing manner:
receiving, at the server computer, event data that characterizes a response of the industrial vehicle to an instance of the event corresponding to the metric; and
updating a score for the instance of the metric, based on the desired performance parameter, associated with the vehicle operator by:
deriving a raw score value based upon the received event data;
aggregating the derived raw score value to previously derived raw scores for the metric associated with the vehicle operator; and
computing a modified score by applying a smoothing filter to the aggregate of raw score values to filter outliers caused by incidental actions of the industrial vehicle from the computed modified score to provide a smoothed score, such that the incidental action of the industrial vehicle does not adversely affect enabling the feature on the industrial vehicle;

comparing the computed modified score with a predetermined modification criterion; and
sending a command back to the industrial vehicle that enables the feature of the industrial vehicle based upon the comparison of the computed modified score with the predetermined modification criterion.

2. The computer implemented process of claim 1 wherein applying a smoothing filter comprises applying a rolling average of the duration of raw score values.

3. The computer implemented process of claim 1 , wherein comparing the computed modified score with a predetermined modification criterion comprises establishing a ranking based upon the computed score.

4. The computer implemented process of claim 1 , wherein sending a command back to the industrial vehicle, further comprises comparing the computed modified score with a predetermined duration variable, and sending the command back to the industrial vehicle where a duration extracted from the event data exceeds the predetermined duration variable.

5. The computer implemented process of claim 1 , wherein identifying, at a server computer, a metric that characterizes an event associated with the operation of an industrial vehicle, the metric having at least one performance parameter to evaluate against the event, comprises:
associating the metric with a geo-feature that links an occurrence of the event associated with the metric to a position within an operating environment of the industrial vehicle.

6. The computer implemented process of claim 5 , wherein comparing the event data to an expected outcome in response to the event comprises:
evaluating industrial vehicle information to determine whether the industrial vehicle performed a desired action in response to the geo-feature.

7. The computer implemented process of claim 1 , wherein sending a command back to the industrial vehicle includes sending a command back to add a new metric to be evaluated.

8. The computer implemented process of claim 1 , wherein sending a command back to the industrial vehicle includes sending a command back to modify a vehicle performance capability.

9. The computer implemented process of claim 1 further comprising applying a ranking based upon the modified score.

10. The computer implemented process of claim 9 further comprising storing the ranking as a time history, wherein comparing the computed modified score with a predetermined modification criterion comprises maintaining a predetermined ranking for a predetermined duration.

11. A system for dynamic industrial vehicle monitoring and modification, the system comprising:
an interface that receives logon information of a vehicle operator, where the vehicle operator must successfully log into an industrial vehicle before the industrial vehicle is fully operational;
a wireless transceiver on the industrial vehicle, wherein the wireless transceiver receives information about a metric that characterizes an event associated with the operation of an industrial vehicle, the metric having at least one performance parameter to evaluate against the event, wherein the performance parameter indicates a desired performance that correlates to correct operation of the industrial vehicle and is used to enable a feature on the industrial vehicle; and
a processor on the industrial vehicle that is programmed to:
detect an encounter of the industrial vehicle corresponding to the event associated with the metric;
collect operation information on a current operating state of the industrial vehicle during the event by communicating with native electrical components of the industrial vehicle across a vehicle network bus so as to monitor a response of the industrial vehicle as a result of the encounter with the event;
generate event data from the collected operational information that characterizes a response of the industrial vehicle to the event corresponding to the metric;
communicate the generated event data to a remote server computer via the wireless transceiver; and
receive from the remote server computer, a command that modifies at least one performance capability or otherwise affects the operation of the industrial vehicle based upon a score computed across previous encounters with the event, where the score is processed based upon:
a raw score value derived from the generated event data;
an aggregation of the derived raw score value to previously derived raw scores for the metric associated with the vehicle operator; and
a modified score computed by applying a smoothing filter to the aggregate of raw score values to filter outliers caused by incidental actions of the industrial vehicle from the computed modified score to provide a smoothed score, such that the incidental action of the industrial vehicle does not adversely affect enabling the feature on the industrial vehicle.

12. The system according to claim 11 , wherein the smoothing filter comprises a rolling average of the duration of raw score values.

13. The system according to claim 11 , wherein the processor receives from the remote server, a command to modify the performance of the industrial vehicle where the filtered score satisfies a predetermined benchmark for a predetermined duration.

14. The system according to claim 11 further comprising:
an environmental based location tracking device on the industrial vehicle that detects location information of the industrial vehicle so as to continuously monitor a current location of the industrial vehicle within the limited-range environment;
wherein:
the processor is further programmed to:
receive geo-feature information about predefined geo-features associated within a predefined, limited-range environment in which the industrial vehicle operates
