AGNOSAR® BSW Case Study

Objective / Overview

Multiple Tier-1 suppliers faced challenges with high integration costs, extended timelines, and expensive BSW licensing from the existing supplier. To address these issues, they adopted AVIN AGNOSAR BSW as a cost-effective and flexible solution for diverse ECU programs, including Instrument Clusters, Digital Clusters, Body Control Modules (BCM), Gateway ECUs, and Passive Entry Passive Start (PEPS) ECUs.

Solution & Approach

Requirement Analysis & Configuration

1. ECU Extract Import & Parameterisation
   Imported ECU extracts into AGNOSAR configuration tools and tailored parameters to match ECU-specific requirements such as communication protocols, diagnostic services, and memory layout.
2. AUTOSAR Stack Configuration
   Configured CAN stack components, including PDU Router, CAN Interface, CAN Driver, and Network Management, to ensure seamless communication across ECUs.
3. Memory Stack Integration
   Integrated AUTOSAR memory modules (NVM, FEE, EA) to support non-volatile data storage and retrieval, ensuring data persistence across power cycles.
4. J1939 Module Integration
   Included J1939 protocol stack to meet Commercial Vehicle OEM requirements, enabling support for transport protocols, diagnostics, and address claiming.
5. Multi-OEM Program Adaptation
   Customized configurations for European, Asian, and British luxury OEMs, ensuring compatibility with diverse vehicle architectures and regional standards.

Security Enhancement

1. Crypto Library Integration
   Embedded cryptographic libraries to enable secure boot, encrypted communication, and message authentication.
2. Crypto Service Manager (CSM)
   Integrated CSM to manage cryptographic operations across modules, ensuring secure data handling and compliance with AUTOSAR Crypto Stack specifications.
3. Secure Communication Protocols
   Implemented secure diagnostics and communication channels using UDS with encryption and authentication layers.
4. Cybersecurity Compliance
   Ensured alignment with ISO 21434 and OEM-specific cybersecurity requirements, including threat modeling and secure update mechanisms.

Testing and Validation

1. Automated CAPL Test Scripts
   Developed CAPL scripts to automate testing of BSW modules, communication stacks, and diagnostic services, reducing manual effort and increasing test coverage.
2. Regression & Compliance Testing
   Conducted regression testing across multiple ECU platforms to ensure stability and consistency. Validated AUTOSAR compliance using standardized test suites.
3. Integration Testing
   Performed end-to-end integration testing across ECUs to verify interoperability, fault tolerance, and performance under real-world conditions.
4. OEM-Specific Validation
   Executed OEM-defined test cases to ensure readiness for production deployment and adherence to program-specific requirements.
