Vehicle Foresight: Customer Correlation of Engine Components Tests Using Life Prediction Modelling

This paper discusses a life prediction modelling approach and its application to customer correlation of engine tests. The approach is based on the realisation that failure of most automotive components can be regarded as the result of degradation, which can be modelled as a stochastic linear damage accumulation process. A case study for validation of an extended oil drain interval is used to illustrate the practical application of the approach.
