Regarding the Importance of the Mileage Distribution for Reliability Prognoses in Automotive Industry

摘要

In automotive industry there are few information about the load of a car in use. Therefore, the available data needs to be used and looked at carefully. Data that is nearly always available is the time in field, given by the date of registration and the date when failure occurred, and the driving distance. The driving distance can be used to describe the load of a car because in most cases the operating time is not known. This data can be used to calculate the mileage distribution of a car, which contains much additional information for safety and reliability analysis. Furthermore, it is useful to adopt testing routines and lifetime distances that are written down in specifications.
