MBSE-Driven Architecture for Next-Generation SDV Development

As vehicles evolve into complex software-defined systems, traditional engineering approaches are proving insufficient to manage the exponential increase in complexity and interdependencies. This case study examines our collaboration with a forward-thinking automotive client to establish a comprehensive Systems Engineering framework supporting Software-Defined Vehicle (SDV) architecture development. The initiative aimed to create a traceable, model-based approach that would connect stakeholder requirements to technical implementation throughout the entire development lifecycle.

Key Technical Aspects:

• Model-Based Systems Engineering: Implementation of SysML methodologies for comprehensive vehicle architecture modeling
• Requirements Traceability: Development of end-to-end traceability from stakeholder needs to hardware specifications
• Modular Architecture Design: Creation of flexible, component-based architecture supporting agile development
• Compliance Integration: Seamless alignment with ISO 26262 and ASPICE standards throughout the engineering process

Technical Implementation:

Our approach to developing the Systems Engineering framework followed a structured methodology:

1. Process Definition: Establishment of comprehensive engineering processes spanning business to architecture design
2. Requirements Engineering: Development of systematic approach for transforming stakeholder needs into technical requirements
3. Architecture Modeling: Creation of complete vehicle-level SysML models with comprehensive subsystem descriptions
4. Specialized System Development: Implementation of tailored approaches for critical systems including Digital Cockpit, ADAS, Telematics, and BCM

Results and Impact

The implementation of our Systems Engineering framework delivered exceptional outcomes:

• Comprehensive Process: Established end-to-end Systems Engineering approach exceeding industry standards
• Complete Vehicle Model: Developed full SysML-based vehicle architecture with traceable requirements
• Critical System Definitions: Created detailed specifications for key vehicle systems with functional and non-functional requirements
• Connected Services Architecture: Designed robust strategy for OTA updates and digital backend integration

This transformative initiative demonstrates how advanced Systems Engineering methodologies, particularly MBSE and SysML, can provide the foundation for successful SDV development, ensuring consistency, traceability, and quality throughout the complex product development lifecycle.
