Enriching the User Experience of a Connected Car with Quantified Self This paper presents the Rxe2x80x99SENS project, the design for a system leveraging the Internet of Things to connect the dots between the user, her car and her environment through the integration of tools belonging to different domains, such as the connected car, the quantified self and web services. The aim of this study is to test a concept through a prototype to explore the possibility of enhancing the user experience of a connected car through the opportune and ubiquitous display of relevant information not only about the car status and the environment, but also the physical status of the driver. The integration of three different user interfaces (i.e., wearable, smartphone and infotainment system) to be used in different moments played a crucial role in the preliminary evaluation of the perceived usefulness and usability of this proofofconcept.

Beyond connected cars: A systems of systems perspective Abstract   The automotive domain is rapidly changing in the last years. Among the different challenges OEMs (i.e. the vehicle manufacturers) are facing, vehicles are evolving into systems of systems. In fact, over the last years vehicles have evolved from disconnected and xe2x80x9cblindxe2x80x9d systems to systems that are (i) able to sense the surrounding environment and (ii) connected with other vehicles, the city, pedestrians, cyclists, etc. Future transportation systems can be seen as a System of Systems (SoS). In an SoS, constituent systems, i.e. the units that compose an SoS, can act as standalone systems, but their cooperation enables new emerging and promising scenarios. While this trend creates new opportunities, it also poses a risk to compromise key qualities such as safety, security, and privacy.  In this paper we focus on the automotive domain and we investigate how to engineer and architect cars in order to build them as constituents of future transportation systems. Our contribution is an architectural viewpoint for System of Systems, which we demonstrate based on an automotive example. Moreover, we contribute a functional reference architecture for cars as constituents of an SoS. This reference architecture can be considered as an imprinting for the implementations that would be devised in specific projects and contexts. We also point out the necessity for a collaboration among different OEMs and with other relevant stakeholders, such as road authorities and smart cities, to properly engineer systems of systems composed of cars, trucks, roads, pedestrians, etc. This work is realized in the context of two Swedish projects coordinated by Volvo Cars and involving some universities and research centers in Sweden and many suppliers of the OEM, including Autoliv, Arccore, Combitech, Cybercom, Knowit, Prevas, AFTechnology, Semcom, and Qamcom.
