A reference architecture for cooperative driving

Cooperative driving systems enable vehicles to adapt their motion to the surrounding traffic situation by utilizing information communicated by other vehicles and infrastructure in the vicinity. How should these systems be designed and integrated into the modern automobile? What are the needed functions, key architectural elements and their relationships? We created a reference architecture that systematically answers these questions and validated it in real world usage scenarios. Key findings concern required services and enabling them via the architecture. We present the reference architecture and discuss how it can influence the design and implementation of such features in automotive systems.

A Functional Architecture for Autonomous Driving

As the Technology Readiness Levels (TRLs) of self-driving vehicles increase, it is necessary to investigate the Electrical/Electronic(E/E) system architectures for autonomous driving, beyond proof-of-concept prototypes. Relevant patterns and anti-patterns need to be raised into debate and documented. This paper presents the principal components needed in a functional architecture for autonomous driving, along with reasoning for how they should be distributed across the architecture. A functional architecture integrating all the concepts and reasoning is also presented.

ATRIUM — Architecting under uncertainty: For ISO 26262 compliance

The ISO 26262 is currently the dominant functional safety standard for electrical and electronic systems in the automotive industry. The Functional Safety Concept subphase in the standard requires the Preliminary Architectural Assumptions (PAA) for allocation of functional safety requirements. This paper justifies the need for, and defines a process ATRIUM, for consistent design of the PAA. ATRIUM is subsequently applied in an industrial case study for a function enabling highly automated driving at one of the largest heavy vehicle manufacturers in Europe, Scania CV AB. The findings from this study, which contributed to ATRIUMs institutionalization at Scania, are presented. The benefits of ATRIUM include (i) a fast and flexible way to refine the PAA, and a framework to (ii) incorporate information from legacy systems into safety design and (iii) rigorously track and document the assumptions and rationale behind architectural decisions under uncertain information. The contributions of this paper are (i) the analysis of the problem (ii) the process ATRIUM and (iii) findings and the discussion from the case study at Scania.

Educating Embedded Systems Hackers: A practitioner's perspective

This paper presents some practical skills which bridge the gap between a sound theoretical education in embedded systems and the skillset acquired by experienced practitioners in the field. The presentation of each skill is accompanied by common solution patterns, state-of-practice technologies, and a set of exercises to provide practical uptake of each skill.

Functional Safety and Evolvable Architectures for Autonomy

The presented paper presents the ongoing Swedish national research project FUSE (FUnctional Safety and Evolvable architectures for autonomy). Some of the research questions addressed in this project are summarized. The research questions are related both to functional safety and the E/E architecture of vehicles aimed for higher degrees of automation, including fully autonomous ones.

Systems Engineering and Architecting for Intelligent Autonomous Systems

This chapter provides practical insights into specific systems engineering and architecture considerations for building autonomous driving systems. It is aimed at the ambitious practitioner with a solid engineering background. We envision such a practitioner to be interested not just in concrete system implementations, but also in borrowing ideas from the general theory of intelligent systems to advance the state of autonomous driving.

Architecture and Safety for Autonomous Heavy Vehicles: ARCHER

Machines are converging towards autonomy. The transition is driven by safety, efficiency, environmental and traditional ‘robotics automation concerns’ (dirty, dull and dangerous applications). Similar trends are seen in several domains including heavy vehicles, cars and aircraft. This transition is, however, facing multiple challenges including how to gradually evolve from current architectures to autonomous systems, limitations in legislation and safety standards, test and verification methodology and human–machine interaction.
