Rapport (övrigt vetenskapligt/konstnärligt)abstract
- In the last decade, electronics and software have replaced many mechanical components in vehicles at an unprecedented rate. New emerging technologies have found their way into the vehicular domain,like for instance, ADAS systems. This change brings some particular challenges with it in terms of functionalities, safety and security. Many vehicle distributed functions require hard real-time and secure communication. Therefore, the electrical and electronic (E/E architectures) architectures are in a continuously adapting trend to meet the new standards.The adaptation from a distributed to a domain-centralized architectureis already present. It is crucial to facilitate reuse of system architectural solutions in order to make system development more efficient. Therefore, we propose the use of communication architectural patterns. We present a method to map communication patterns on a certain layer ofabstraction. The method has been evaluated through several industrialuse cases. Furthermore, this work sets precedence for future research and development, as well as future applications of the method.

Konferensbidrag (refereegranskat)abstract
- The continuous innovation and advancement in vehicle software functionality has driven the evolution of its deployment platforms through several generations of vehicular Electrical and Electronic (E/E) architectures. It is a daunting task to evaluate pros and cons of allocating the new as well as legacy functionality to these architectures. In this paper, we propose a novel approach that uses communication patterns as a metric to evaluate different vehicular E/E architectures and propose a suitable allocation for the functionality. First, we present the characteristics of these patterns in vehicular systems that are derived from the state-of-the-art review, standardized vehicular software architectures, well-known onboard vehicular, communication protocols, industrial requirements and use cases. We leverage the derived communication patterns and their characteristics to propose an evaluation approach for different architectural solutions for the functionality. We utilize a use case from the vehicle industry to demonstrate the applicability and usability of the proposed approach.
