Abstract

In the automotive industry, an important field of experimentation is system validation. The aim is to demonstrate that the system (e.g. engine, transmission, exhaust gas aftertreatment system, complete vehicle, etc.) fulfills the technical specifications (e.g. in terms of a reliability target) as well as the customer expectations. The system is required to be of sufficient maturity at the beginning of the validation phase so that there is a realistic chance to pass the validation program without failures. Consequently, the objective of these type of experimentation is not to optimize a product but to optimize its validation program. This is done by a systematic and representative variation of system load parameters spanning the customer usage space.



The presentation shows an algorithm including examples of this DoE adaptation which has been applied successfully in different vehicle development projects.
