Crafting a Systems Engineering Framework for the SDV Architectures
Systems engineering case study
Background
Y-mobility was entrusted with leading a transformative journey to define and accompany our client’s Systems Engineering and Design Framework. The project aimed to establish robust processes, tools, and models to elevate the full vehicle architecture and to accompany the client through all the stages of product development, from defining stakeholder requirements to developing System of Interest descriptions for all relevant vehicle Systems.
Objectives
The client recognised the pivotal role of Systems Engineering in the modern automotive landscape. Their objective was to define a comprehensive Systems Engineering Process from the business level to architecture design, ensuring maturity from concept to production.
Based on this, Y-Mobility was tasked with creating a system description on vehicle-level as well as subsystems.
The defined vehicle architecture has been subsequently modelled with MBSE and SysML approaches.
Result was a full vehicle description and a full Vehicle SysML model ensuring traceability from initial stakeholder requirements to system architecture.
Our Approach
We embraced a holistic and agile approach, focusing on not just meeting industry standards but surpassing them. We aimed to define and implement a Systems Engineering Process and MBSE based architecture definition that would be a beacon for full vehicle architecture development ensuring traceability from early concept to production.
The Solution
Drawing from our experience, we designed a tailored solution based on Systems Engineering approaches and MBSE to support the definition of a SDV vehicle architecture. The solution allows our clients to define a flexible and modular architecture in an agile environment and provide a framework to implement their suppliers and stakeholder requirements.
Implementation
The journey continued with the crafting of Systems Requirements, Definitions, and Development Approach. Leveraging requirements management tools and different SysML tools, we meticulously developed systems requirements from stakeholder needs down to the hardware level of each subsystem in the vehicle architecture.
Based on the developed system descriptions and SysML Models we created impact studies and Functional and Non-Functional Feature Requirements for critical Systems such as Digital Cockpit, ADAS, Telematics Unit, and BCM. We supported the client in the development of a Diagnostic Strategy as well as Networking Architecture. Based on stakeholder needs we defined a strategy and architecture to offer connected services such as OTA via a digital backend.
This was accompanied by defining systems decomposition, terminology, and functionality, aligning with ISO 26262 and ASPICE standards.
The Result
The client now possesses a comprehensive Systems Engineering Process that not only meets but exceeds industry standards. The Systems Modelling phase ensured accurate representation of the vehicle-level and subsystems architecture, meeting the highest safety and performance benchmarks. We continue working with the client in the development of the systems specs.
