The functionality is described at the logical level, without dependence on specific implementation technologies.MethodEngineering design has been used as the research method, which focuses on creating solutions intended for practical application. The architecture has been refined and applied over a 5 year period to the construction of prototype autonomous vehicles in three different categories, with both academic and industrial stakeholders.ResultsThe architectural components are divided into categories pertaining to (i) perception, (ii) decision and control, and (iii) vehicle platform manipulation. The architecture itself is divided into two layers comprising the vehicle platform and a cognitive driving intelligence. The distribution of components among the architectural layers considers two extremes: one where the vehicle platform is as "dumb" as possible, and the other, where the vehicle platform can be treated as an autonomous system with limited intelligence. We recommend a clean split between the driving intelligence and the vehicle platform. The architecture description includes identification of stakeholder concerns, which are grouped under the business and engineering categories. A comparison with similar architectures is also made, wherein we claim that the presence of explicit components for world modeling, semantic understanding, and vehicle platform abstraction seem unique to our architecture.ConclusionThe concluding discussion examines the influences of implementation technologies on functional architectures and how an architecture is affected when a human driver is replaced by a computer. The discussion also proposes that reduction and acceleration of testing, verification, and validation processes is the key to incorporating continuous deployment processes.

We investigate the relation between CPS, Systems Engineering (SE) and the Conceive - Design - Implement -Operate (CDIO) engineering education initiative with the aim to find ways of improving current CPS education. With its emphasis on experiences with realistic engineering settings, lifecycle perspective and complementary skills in communication and collaboration, CDIO provides several ingredients that are essential for future engineers. SE with its set of best practices and systems thinking, provides guidelines and practices of strong relevance for most (if not all) engineering programs and especially for those involving the engineering of highly complex systems such as CPS. We conclude that applying a CDIO approach for a CPS program together with infusion of a suitable portion of SE practices appears to be a promising way forward to reform CPS programs. We discuss how such SE practices can be integrated into engineering programs and in particular propose aspects of SE that would be useful to incorporate into capstone courses (larger education projects in the final master level stages).

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.
