Claims20
A method of monitoring a status of a vehicle component of a vehicle, the method comprising:
- obtaining, via one or more vehicular telemetry systems disposed in the vehicle, operational data from the vehicle component of the vehicle, the vehicle component comprising a battery of the vehicle;
- deriving a moving average from the operational data;
- deriving, from the operational data, one or more signals representative of a current operation of the battery;
- determining the status of the battery at least in part by:
- evaluating at least the moving average and the one or more signals in relation to a monitoring framework comprising an upper control limit, a mean, a minus one standard deviation, a minus two standard deviation, and a lower control limit derived from the operational data, wherein:
- the evaluating comprises identifying one or more patterns exhibited by the moving average and/or the one or more signals with respect to the upper control limit, the mean, the minus one standard deviation, the minus two standard deviation, and the lower control limit, wherein identifying the one or more patterns comprises identifying a first pattern indicating a replacement status of the battery when the moving average is decreasing from the minus one standard deviation to the minus two standard deviation with first signals of the one or more signals between the mean and the lower control limit and second signals of the one or more signals at or below the lower control limit;
- and
- determining, based on the evaluating, the replacement status of the battery;
- and
- indicating, based on the determined replacement status, a predicted failure of and/or recommended replacement of the battery.
A system configured to monitor a status of a vehicle component of a vehicle, the system comprising:
- a telematics hardware device disposed in the vehicle configured to monitor the vehicle component of the vehicle, the vehicle component comprising a battery of the vehicle;
- a remote device configured to:
- obtain, from the telematics hardware device, operational data regarding the battery of the vehicle;
- derive a moving average from the operational data;
- derive, from the operational data, one or more signals representative of a current operation of the battery;
- and
- determine the status of the battery at least in part by:
- evaluating at least the moving average and the one or more signals in relation to a monitoring framework comprising an upper control limit, a mean, a minus one standard deviation, a minus two standard deviation, and a lower control limit derived from the operational data, wherein:
- the evaluating comprises identifying one or more patterns exhibited by the moving average and/or the one or more signals with respect to the upper control limit, the mean, the minus one standard deviation, the minus two standard deviation, and the lower control limit, wherein identifying the one or more patterns comprises identifying a first pattern indicating a replacement status of the battery when the moving average is decreasing from the minus one standard deviation to the minus two standard deviation with first signals of the one or more signals between the mean and the lower control limit and second signals of the one or more signals at or below the lower control limit;
- and
- determining, based on the evaluating, the replacement status of the battery;
- and
- indicate, based on the determined replacement status, a predicted failure of and/or recommended replacement of the battery.
At least one non-transitory computer-readable storage medium storing processor-executable instructions that, when executed by at least one processor, cause the at least one processor to perform a method of monitoring a status of a vehicle component of a vehicle, the method comprising:
- obtaining, via one or more vehicular telemetry systems disposed in the vehicle, operational data from the vehicle component of the vehicle, the vehicle component comprising a battery of the vehicle;
- deriving a moving average from the operational data;
- deriving, from the operational data, one or more signals representative of a current operation of the battery;
- determining the status of the battery at least in part by:
- evaluating at least the moving average and the one or more signals in relation to a monitoring framework comprising an upper control limit, a mean, a minus one standard deviation, a minus two standard deviation, and a lower control limit derived from the operational data, wherein:
- the evaluating comprises identifying one or more patterns exhibited by the moving average and/or the one or more signals with respect to the upper control limit, the mean, the minus one standard deviation, the minus two standard deviation, and the lower control limit, wherein identifying the one or more patterns comprises identifying a first pattern indicating a replacement status of the battery when the moving average is decreasing from the minus one standard deviation to the minus two standard deviation with first signals of the one or more signals between the mean and the lower control limit and second signals of the one or more signals at or below the lower control limit;
- and
- determining, based on the evaluating, the replacement status of the battery;
- and
- indicating, based on the determined replacement status, a predicted failure of and/or recommended replacement of the battery.
