Abstract

Apparatus, device, methods and system relating to a vehicular telemetry environment for monitoring vehicle components and providing indications towards the condition of the vehicle components and providing optimal indications towards replacement or maintenance of vehicle components before vehicle component failure.

First claim

What is claimed is:

1. A method of identifying real time predictive indicators of operational vehicle component status, the method comprising:
accessing at least one record of operational component data that includes operational values from at least one vehicle component from at least one vehicle, said operational values representative of an operational life cycle use of said at least one vehicle component, said operational values further based upon a measured component event;
accessing at least one record of management event data, said management event data containing at least one vehicle component event data point for at least one vehicle;
filtering said operational component data;
deriving from said operational component data at least one signal representative of said measured component event, wherein deriving the at least one signal comprises:
deriving a first signal from said operational component data when a single data point from said operational values is above an upper control limit or below a lower control limit,
deriving a second signal from said operational component data when a series of eight consecutive data points from said operational values are between a mean value and the upper control limit or between the mean value and the lower control limit,
deriving a third signal from said operational component data when a series of four out of five consecutive data points from said operational values are between the mean value and greater than plus one standard deviation or between the mean value and greater than minus one standard deviation, and
deriving a fourth signal from said operational component data when a series of two out of three consecutive data points from said operational values are between the mean value and greater than plus two standard deviation or the mean value and greater than minus two standard deviation;

analyzing the filtered operational component data and the at least one signal in relation to said at least one vehicle component event data point, wherein said analyzing comprises identifying one or more patterns exhibited by the filtered operational component data and a grouping of any combination of the first signal, the second signal, the third signal, and the fourth signal;
identifying, based on the analyzing, whether a status of the at least one vehicle component corresponds to a first status represented by a first pattern of the one or more patterns, a second status represented by a second pattern of the one or more patterns, a third status represented by a third pattern of the one or more patterns, or a fourth status represented by a fourth pattern of the one or more patterns; and
identifying, for real time use in fleet management, real time predictive indicators representing the identified status of the at least one vehicle component, wherein identifying the real time predictive indicators comprises:
in response to identifying the identified status of the at least one vehicle component as corresponding to the first status, identifying one or more first real time predictive indicators representing the first status based on the first pattern,
in response to identifying the identified status of the at least one vehicle component as corresponding to the second status, identifying one or more second real time predictive indicators representing the second status based on the second pattern,
in response to identifying the identified status of the at least one vehicle component as corresponding to the third status, identifying one or more third real time predictive indicators representing the third status based on the third pattern, and
in response to identifying the identified status of the at least one vehicle component as corresponding to the fourth status, identifying one or more fourth real time predictive indicators representing the fourth status based on the fourth pattern.

2. A method as in claim 1 , wherein accessing at least one record of operational component data comprises accessing at least one record of data representative of at least one category of fuel and air metering, emission control, ignition system control, vehicle idle speed control, transmission control, hybrid propulsion, or battery, or data based upon at least one of on-board diagnostic fault codes, trouble codes, manufacturer codes, generic codes or vehicle specific codes.

3. A method as in claim 1 , wherein accessing at least one record of operational component, data that, includes operational values from at least one vehicle component from at least one vehicle comprises accessing the at least one record of the operational component data that includes the operational values from the at least one vehicle component from the at least one vehicle that is representative of a portion of operational values from a new component to a failed component.

4. A method as in claim 1 , wherein accessing at least one record of operational component data that includes operational values from at least one vehicle component from at least one vehicle based upon a measured component event comprises accessing the at least one record of the operational component data that, includes the operational values from the at least one vehicle component from the at least one vehicle based upon an event that provides a high operational load within the limits of said at least one vehicle component.

5. A method as in claim 1 , wherein accessing at least one record of management, event data comprises accessing at least one record of at least one of component maintenance indication, component repair indication, component failure indication or component replacement indication.

6. A method as in claim 1 , wherein said filtering comprises determining a moving average or a running average of said operational values.

7. A method as in claim 1 , further comprising a monitoring indicator framework including the lower control limit, the upper control limit, the plus one standard deviation, the plus two standard deviation, the mean value, the minus one standard deviation and the minus two standard deviation derived from said operational component data.

8. A method as in claim 1 , wherein identifying real time predictive indicators further comprises:
in response to identifying the identified status of the at least one vehicle component as corresponding to a fifth status, identifying one or more fifth real time predictive indicators representing the fifth status, wherein said one or more fifth real time predictive indicators comprise at least one of: a moving average of said operational component data decreasing from the mean value to the minus one standard deviation, a moving average of said operational component data decreasing from the minus one standard deviation to the minus two standard deviation, a moving average that reaches the minus two standard deviation, and a moving average rising from the minus one standard deviation to above the plus one standard deviation followed by a moving average between the plus one standard deviation and the plus two standard deviation.

9. A method as in claim 1 , wherein said one or more first real time predictive indicators comprise a moving average between the plus one standard deviation and plus two standard deviation.

10. A method as in claim 1 , wherein said one or more second real time predictive indicators comprise a moving average between the plus one standard deviation and the minus two standard deviation.

11. A method as in claim 1 , wherein said one or more third real time predictive indicators comprise a moving average at or below the minus two standard deviation.

12. A method as in claim 1 , wherein said one or more fourth real time predictive indicators compri
