A METHOD FOR PREDICTING A REMAINING LIFETIME PARAMETER OF A COMPONENT

A method for predicting a remaining lifetime parameter of a component installed in a system, the method comprising:- repeatedly sensing at least one parameter of the system to obtain a history of data values;- fitting an aging pattern to the data values; and- determining a remaining lifetime paramet...

Zusammenfassung:	A method for predicting a remaining lifetime parameter of a component installed in a system, the method comprising:- repeatedly sensing at least one parameter of the system to obtain a history of data values;- fitting an aging pattern to the data values; and- determining a remaining lifetime parameter of the component from the aging pattern,At least some data values are erased with time such that the fitting is based on a subset of the data values determined since an initialization of the algorithm, wherein data values from an initial phase are not erased but retained as anchor values for the fitting throughout the lifetime determination of the component and/or the aging pattern for determining the remaining lifetime parameter is automatically selected from a predefined set of different aging patterns and/or a change of the component is automatically detected by evaluating the data values.
