Smart Antenna & Telematics

Complete system architecture of a Smart Antenna and Telematic Control Unit for a Tier 1 supplier in Germany, integrating connectivity, cybersecurity and embedded system safety.

Challenge

• System architecture from scratch: static design (interfaces, design elements), dynamic design (use cases to functions) and hardware-software integration
• A flexible core product platform handling variants and configurations (150% approach)
• Aligning hardware, software and cybersecurity teams around one architecture
• Security compliance (ISO/SAE 21434) and cross-cutting concerns such as diagnostics and power management

What we did

• Model-based architecture documentation with Enterprise Architect and Polarion LiveDocs in an Agile framework
• Variant Tree analysis and configuration management
• Coordination with the Cybersecurity Manager on TARA prerequisites per ISO/SAE 21434
• Coaching and methodology introduction across departments

Results

• Core product platform developed with the 150% approach
• Improved cross-department processes and technical work products
• Aligned hardware, software and cybersecurity requirements for certification readiness
