Structured Development and Evaluation of Electric/Electronic-Architectures of the Electric Power Train

The evaluation of electric/electronic-architectures is the main topic of this document. The electric power train is chosen as example system, as it embodies the typical challenges of modern e/e-architecture development. New electric and electronic functionalities are developed and required in the automotive industry and already existing mechanically realized functionalities are exchanged by electric and electronic ones. The electric power train meats both occurrences at one time. An introduction is given to the widely used scenario based evaluation method of electrical systems and software, as well as two alternative evaluation methods. The methods are analyzed regarding their usability to the given use-case. Finally the chosen method is described in detail. With the topic of evaluation, this paper is to be understood as a contribution to the optimization of e/e-architectures; in specific to the logical allocation, functional integration, and interconnection of the to be integrated technical modules and components.
