Abstract [en]

The use of embedded computers in modern automobiles is enabling increasingly autonomous features. Electronic power train management and applications in active safety, cooperative driving and navigation show an underlying trend of the transfer of responsibilities from the human driver to a vehicle's (semi-)autonomous subsystems. The logical culmination ofthis trend would be a completely autonomous vehicle. How should existing vehicle architectures be evolved to sustain the development and growth of autonomous functions? We explore the principal problems with existing architectures, caused due to ad hoc addition of (semi-) autonomous features and argue that it is time to rethink automotive architectures from an autonomous systems perspective. We introduce a pattern that can help architects and designers to think in terms of autonomy and suggest where the application of autonomous systems thinking should begin, in the context of architecture development.

Abstract [en]

The increasing usage of electronics and software in a modern automobile enables realization of many advanced features. One such feature is autonomous driving. Autonomous driving means that a human driver’s intervention is not required to drive the automobile; rather, theautomobile is capable of driving itself. Achieving automobile autonomyrequires research in several areas, one of which is the area of automotive electrical/electronics (E/E) architectures. These architectures deal with the design of the computer hardware and software present inside various subsystems of the vehicle, with particular attention to their interaction and modularization. The aim of this thesis is to investigate how automotive E/E architectures should be designed so that 1) it ispossible to realize autonomous features and 2) a smooth transition canbe made from existing E/E architectures, which have no explicit support for autonomy, to future E/E architectures that are explicitly designed for autonomy.The thesis begins its investigation by considering the specific problem of creating autonomous behavior under cooperative driving condi-tions. Cooperative driving conditions are those where continuous wireless communication exists between a vehicle and its surroundings, which consist of the local road infrastructure as well as the other vehicles in the vicinity. In this work, we define an original reference architecture for cooperative driving. The reference architecture demonstrates how a subsystem with specific autonomy features can be plugged into an existing E/E architecture, in order to realize autonomous driving capabilities. Two salient features of the reference architecture are that it isminimally invasive and that it does not dictate specific implementation technologies. The reference architecture has been instantiated on two separate occasions and is the main contribution of this thesis. Another contribution of this thesis is a novel approach to the design of general, autonomous, embedded systems architectures. The approach introduces an artificial consciousness within the architecture, that understands the overall purpose of the system and also how the different existing subsystems should work together in order to meet that purpose.This approach can enable progressive autonomy in existing embedded systems architectures, over successive design iterations.
