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.
Claims20
A method to assess historical vehicle component maintenance and identify predictive indicators of maintenance events comprising:
- accessing a record of operational component data, said operational component data including operational values from a vehicle component from a vehicle, said operational values representative of an operational life cycle use of said vehicle component, said operational values further based upon a measured component event,
- accessing a record of management event data, said management event data containing a vehicle component event data point for said vehicle, said vehicle component event data point including a date and a maintenance event indication,
- associating said record of operational component data with said record of management event data,
- filtering said operational component data, said filtering including a moving average of said operational component data, an upper control limit of said operational component data, plus two standard deviation of said operational component data, plus one standard deviation of said operational component data, a mean of said operational component data, minus one standard deviation of said operational component data, minus two standard deviation of said operational component data and a lower control limit of said operational component data,
- deriving from said operational component data at least one signal representative of operational use of said vehicle component for said measured component event,
- comparing filtered operational component data with said at least one signal prior to said vehicle component event data point thereby identifying indicators associated with said maintenance event indication.

A system to assess historical vehicle component maintenance and identify predictive indicators of maintenance events comprising:
- a telematics hardware device including a processor, memory, firmware and communications capability,
- a remote device including a processor memory software and communications capability
- said telematics hardware device monitoring at least one vehicle component from at least one vehicle and logging operational component data of said at least one vehicle component, said telematics hardware device communicating a log of operational component data to said remote device
- said remote device said remote device accessing a record of operational component data, said operational component data including operational values from a vehicle component from a vehicle, said operational values representative of an operational life cycle use of said vehicle component, said operational values further based upon a measured component event,
- said remote device accessing a record of management event data, said management event data containing a vehicle component event data point for said vehicle, said vehicle component event data point including a date and a maintenance event indication,
- said remote device associating said record of operational component data with said record of management event data,
- said remote device filtering said operational component data, said filtering including a moving average of said operational component data, an upper control limit of said operational component data, plus two standard deviation of said operational component data, plus one standard deviation of said operational component data, a mean of said operational component data, minus one standard deviation of said operational component data, minus two standard deviation of said operational component data and a lower control limit of said operational component data,
- said remote device deriving from said operational component data at least one signal representative of operational use of said vehicle component for said measured component event,
- said remote device comparing filtered operational component data with said at least one signal prior to said vehicle component event data point thereby identifying indicators associated with said maintenance event indication.
