This project involved the complete system architectural design of a Smart Antenna and Telematic Control Unit for a Tier 1 supplier in Germany, integrating advanced connectivity, cybersecurity, and embedded system safety.
Project Overview
We initiated the system architecture from scratch, covering static design (interfaces, design elements), dynamic design (use case analysis to function design), and hardware-software integration. Features included e-Call, SIM, Voice, SMS, Security Storage, Cellular Data, FOTA/OTA, NFC, UWB, BLE, Bluetooth, Infotainment, MCU, SoC, WiFi, user-application framework, V2X, GNSS, Tuner, Internet Access, Driver Warning, Car Access, Positioning, and Stolen Vehicle Tracking.
Approach / Methodology
We combine hands-on coaching, independent assessments, and structured methodologies. Our approach emphasizes early identification of risks, traceable documentation, and alignment with both product and organizational goals.
Project: Architectural Design of Smart Antenna & Telematic Control Unit (Tier 1 Supplier)
Challenge / Problem Statement The client required the complete system architectural design of a Smart Antenna and Telematic Control Unit from scratch. Key challenges included:
Defining both static and dynamic system architecture with complex hardware-software interfaces
Developing a flexible Core Product Platform capable of handling variants and configurations (150% approach)
Aligning multi-disciplinary teams (hardware, software, cybersecurity) around a unified architecture
Ensuring compliance with security standards (ISO 21434) and managing cross-cutting concerns (diagnostics, power management, etc.)
Key Achievements
Developed core product platform using the “150% approach” and configuration management.
Enhanced cross-department processes and technical work products through coaching and methodology introduction.
Ensured alignment between hardware, software, and cybersecurity requirements for certification readiness.
Methodology / Process / Action Taken
1. System Architecture Initiation & Definition
