Challenges in homologation process of vehicles with artificial intelligence
The traditional automotive homologation processes aim to ensure the safety of vehicles on public roads. Autonomous Vehicles (AV) with Artificial Intelligence (AI) are difficult to account for in these conventional processes. This research aims to map and attempt to close the gaps in the areas of testing and approval of such automated and connected vehicles. During our research into the homologation process of traditional vehicles; functional safety issues, challenges of AI in safety critical systems, along with questions of cyber security were investigated. Our process focuses on the integration of the already existing functions and prototypes into new products safely. As a key result, we managed to identify the main gaps between Information and Communication Technology (ICT) and automotive technology: the rigidity of the automotive homologation process, functional safety, AI in safety critical areas and we propose a solution
On Using Blockchains for Safety-Critical Systems
Innovation in the world of today is mainly driven by software. Companies need
to continuously rejuvenate their product portfolios with new features to stay
ahead of their competitors. For example, recent trends explore the application
of blockchains to domains other than finance. This paper analyzes the
state-of-the-art for safety-critical systems as found in modern vehicles like
self-driving cars, smart energy systems, and home automation focusing on
specific challenges where key ideas behind blockchains might be applicable.
Next, potential benefits unlocked by applying such ideas are presented and
discussed for the respective usage scenario. Finally, a research agenda is
outlined to summarize remaining challenges for successfully applying
blockchains to safety-critical cyber-physical systems
Potholes and Paperwork: Improving Cross-Border Integration and Regulation of the Automotive Industry
Divergent regulations and border regimes in Canada and the US are threatening the integrated, cross-border structure of the Canadian auto industry. It is time for common regulations governing safety, fuel consumption and environmental protection, and faster, more efficient border clearances.trade policy, Auto Pact, automotive industry
Synergizing Roadway Infrastructure Investment with Digital Infrastructure for Infrastructure-Based Connected Vehicle Applications: Review of Current Status and Future Directions
The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.The safety, mobility, environmental and economic benefits of Connected and Autonomous Vehicles (CAVs) are potentially dramatic. However, realization of these benefits largely hinges on the timely upgrading of the existing transportation system. CAVs must be enabled to send and receive data to and from other vehicles and drivers (V2V communication) and to and from infrastructure (V2I communication). Further, infrastructure and the transportation agencies that manage it must be able to collect, process, distribute and archive these data quickly, reliably, and securely. This paper focuses on current digital roadway infrastructure initiatives and highlights the importance of including digital infrastructure investment alongside more traditional infrastructure investment to keep up with the auto industry's push towards this real time communication and data processing capability. Agencies responsible for transportation infrastructure construction and management must collaborate, establishing national and international platforms to guide the planning, deployment and management of digital infrastructure in their jurisdictions. This will help create standardized interoperable national and international systems so that CAV technology is not deployed in a haphazard and uncoordinated manner
A synthesis of logic and bio-inspired techniques in the design of dependable systems
Much of the development of model-based design and dependability analysis in the design of dependable systems, including software intensive systems, can be attributed to the application of advances in formal logic and its application to fault forecasting and verification of systems. In parallel, work on bio-inspired technologies has shown potential for the evolutionary design of engineering systems via automated exploration of potentially large design spaces. We have not yet seen the emergence of a design paradigm that effectively combines these two techniques, schematically founded on the two pillars of formal logic and biology, from the early stages of, and throughout, the design lifecycle. Such a design paradigm would apply these techniques synergistically and systematically to enable optimal refinement of new designs which can be driven effectively by dependability requirements. The paper sketches such a model-centric paradigm for the design of dependable systems, presented in the scope of the HiP-HOPS tool and technique, that brings these technologies together to realise their combined potential benefits. The paper begins by identifying current challenges in model-based safety assessment and then overviews the use of meta-heuristics at various stages of the design lifecycle covering topics that span from allocation of dependability requirements, through dependability analysis, to multi-objective optimisation of system architectures and maintenance schedules
Business Case and Technology Analysis for 5G Low Latency Applications
A large number of new consumer and industrial applications are likely to
change the classic operator's business models and provide a wide range of new
markets to enter. This article analyses the most relevant 5G use cases that
require ultra-low latency, from both technical and business perspectives. Low
latency services pose challenging requirements to the network, and to fulfill
them operators need to invest in costly changes in their network. In this
sense, it is not clear whether such investments are going to be amortized with
these new business models. In light of this, specific applications and
requirements are described and the potential market benefits for operators are
analysed. Conclusions show that operators have clear opportunities to add value
and position themselves strongly with the increasing number of services to be
provided by 5G.Comment: 18 pages, 5 figure
Safety-Critical Systems and Agile Development: A Mapping Study
In the last decades, agile methods had a huge impact on how software is
developed. In many cases, this has led to significant benefits, such as quality
and speed of software deliveries to customers. However, safety-critical systems
have widely been dismissed from benefiting from agile methods. Products that
include safety critical aspects are therefore faced with a situation in which
the development of safety-critical parts can significantly limit the potential
speed-up through agile methods, for the full product, but also in the
non-safety critical parts. For such products, the ability to develop
safety-critical software in an agile way will generate a competitive advantage.
In order to enable future research in this important area, we present in this
paper a mapping of the current state of practice based on {a mixed method
approach}. Starting from a workshop with experts from six large Swedish product
development companies we develop a lens for our analysis. We then present a
systematic mapping study on safety-critical systems and agile development
through this lens in order to map potential benefits, challenges, and solution
candidates for guiding future research.Comment: Accepted at Euromicro Conf. on Software Engineering and Advanced
