Objective
As modern ECUs evolved to support multiple network interfaces and increased software modularity, a leading European Tier-1 supplier partnered with AVIN Systems to streamline its AUTOSAR Classic platform integration. The existing integration process faced challenges with multi-bus (CAN, LIN, FlexRay) communication, post-build configurability, and OEM-specific extensions. AVIN was engaged to develop a scalable and standardized integration framework that ensured interoperability, minimized rework, and accelerated validation cycles across various vehicle programs.
Solution
Requirement Analysis & Configuration
Performed deep analysis of ECU extracts and OEM-specific parameters. Generated BSW configurations (COM, DCM, OS, NM, NVM) with post-build flexibility to support scalable integration.
Network Management and Development
Implemented CAN and FlexRay network modules with partial networking and PNC timing automation, Ensured deterministic message handling across power modes.
Memory and Bootloader Integration
Developed Flash Bootloaders (FBL) conforming to UDS and ISO 14229, Validated interoperability across hardware variants to reduce reflash time.
Security Enhancement
Integrated AUTOSAR Crypto Service Manager (CSM) and hardware-based HSM modules, Strengthened ECU security with secure sessions and integrity checks.
Testing and Validation
Automated CAPL and Python test cases for communication and diagnostics, achieved full traceability using model-driven validation and ASPICE metrics.
Impacts
- Reduced ECU integration and validation timelines by 30–40%.
- Achieved full traceability and compliance with AUTOSAR R4.x standards.
- Enhanced scalability across multiple ECU variants and OEM platforms.
- Significantly improved communication performance and diagnostic reliability.
