Method and Apparatus for Determining a Residual Service Life based on a Predictive Diagnosis of Components of an Electric Drive System Using Artificial Intelligence Techniques

Abstract

A computer-implemented method for providing a residual service life based on a diagnosis of components of an electric drive system in a vehicle, includes recording distributions of a plurality of operating parameters comprising at least one sensor parameter and/or at least one control parameter, in the vehicle; using a plurality of diagnostic models for a plurality of fault types, each of which is configured to detect a specific fault type in one of the components based on at least some of the plurality of operating parameters and to signal corresponding fault information associated with the fault type; determining the residual service life using a residual usage model depending on the signaled corresponding fault information, the residual usage model configured to indicate the residual service life depending on the corresponding fault information from the plurality of diagnostic models; and signaling the residual service life.
