About this book

Jonas Maier presents a method for designing decentralized, spatially structured E/E architectures. A coupled approach of package and wiring harness models is used for this purpose. Relevant data can be exchanged between the models by transferring the boundary conditions. The spatial division of the vehicle into zones is optimized by an extended k-means algorithm. Based on this, the connection paths between the components are optimized with regard to various boundary conditions. This results in a complexity reduction of the wiring harness as well as the overall architecture.

Chapter 1. Introduction

Abstract

Products and their systems do not only need to fulfill one criterion, in most cases they are designed in a trade-off between multiple aspects. As an example, one can think of a vehicle traction battery, that should have a low weight, high energy content, temperature and vibration resistance and a long lifetime. It is not possible to fulfill all these completely, therefore technical development needs to identify the best compromise in this area of conflict.

Chapter 2. Vehicle Electric/Electronic Architectures

Abstract

The aim of this chapter is the definition of basic terms and concepts as well as the state-of-the-art. In the following a description of different system concepts is given, which are substantiated by the exemplification of its layers. Based on this, the system is contextualized in the entire development process and subsequently the research gap is identified.

Chapter 3. Optimization of Electric/Electronic Architectures

Abstract

EEAs are seen as vehicles’ backbones and optimizing them often results in benefits for other systems. Although optimization brings progress for itself and other systems, it is hard to identify optima for EEAs due to its interdisciplinary and conflicting design criteria. Before the actions taken for this research are presented, it is necessary to point out the results of the previous action planning. In this chapter the problem is structured into core aspects.

Chapter 4. Design of Zonal Electric/Electronic Architectures

Abstract

So far implementation of zonal architectures has been limited to prototype vehicles and systematic approaches for their design have not established. To tackle this issue, the individual solutions discussed in Chapter 3 with respect to the system and its environment described in Chapter 2 are joined to realize a holistic design method. Hence a method is introduced for designing a zonal architecture based on the optimization of traction battery, power distribution and wiring harness, while ensuring compatibility with vehicle packaging.

Chapter 5. Case Study and Discussion

Abstract

The action previously planned and taken resulted in a method, which is evaluated in this chapter. The aim is to generate an understanding of the suitability of the method, therefore a case study is conducted and the different solution variants are discussed. The case study consists of two vehicle data sets and four modifications of these, which ensure the generality of the method.

Chapter 6. Summary and Outlook

Abstract

The research questions of this thesis were derived from the structural shift in EEAs. This is linked to the fact, that decentralized or domain centralized architectures were structured by technological or functional aspects, while a zone centralization requires the structuring by geometrical aspects. As the problem posed involves an interdisciplinary complex system, a limitation to relevant aspects is essential for the identification of a meaningful solution.
