Abstract
The automotive industry is facing significant technological barriers with the shift toward Connected and Autonomous Vehicles (CAVs). With technology trends such as Big Data and the Internet of Things (IoT), demonstrating that effective utilisation of data can lead to a competitive advantage, the question becomes: what is the best approach to gathering, disseminating and utilising the data available within the vehicular platform? Key challenges that have arisen during this adoption period include: how should access to the data existing within current vehicular platforms be managed and how can existing application development paradigms, such as Publish/Subscribe and Service Orientation, be employed to ease development of the increasingly di- verse range of systems integrating with vehicles. The initial stage of research aimed to address these challenges associated with Vehicle-to-Cloud (V2C) applications, whose requirements cannot be precisely known in advance, by introducing a multi-broker Publish/Subscribe system. In order to ensure effective coupling between the Vehicle and Cloud components, synchronisation between the two brokers was managed through an example optimisation function laying the framework for delivering cost constrained applications. Through exploring the capabilities of the proposed multi-broker Publish/Subscribe system several limitations were highlighted - unexposed signal data; and a high, often fixed signal latency. Emerging complementary trends in Automotive Networking include the adoption of Automotive-compliant Ethernet PHYs, Quality of Service (QoS) standards (802.1Qav and 802.1Qbv [1]) and Service Orientated Architectures (enabled through IP abstraction). Service Orientated Architectures could address the challenges associated with unexposed signal data when supported by higher speed networking by allowing services to request the data dynamically rather than requiring firmware changes to expose new data. This led to proposing a new non deterministic method, that can run alongside statically configured safety-critical streams, for delivering applications on an Ethernet-based network utilising a dynamic priority allocation model, which assigns Ethernet frame parameters at run-time, in order to meet its application latency requirements whilst remaining responsive to changes in application topology. With the contributions from this research, the automotive industry now has: an alternative to the traditional bottom-up network development approach that applies the same constraint model to all traffic; and a Vehicle- to-Cloud application development framework that allows for applications to be developed completely independently of vehicular hardware while support- ing vehicle-side decision making. By establishing these alternative approaches early, the adoption of Automotive Ethernet, IP, Service Orientated Architectures and integrated Vehicle-to-Cloud solutions, the automotive industry can make informed decisions with regard to vehicular platform design.
