Body Electronics & AUTOSAR

Body Electronics & AUTOSAR

Since 2003, some of the world’s largest Automotive OEMs have joined the AUTOSAR global development partnership with an objective to establish open and standardized software architecture for Automotive electronic control units (ECUs).

Today, the automotive industry is being disrupted by OEMs, Tier-1s, tool vendors, semiconductor suppliers, and integrators are making significant technological investments in ECUs, Zone Control Units (ZCUs), Domain Control Units (DCUs), Vehicle Central Computing Units (VCCUs), and Collaborative Cognitive Control Units (CCCUs). Some of the possibilities enabled by Sasken in realizing AUTOSAR are:

  • Enabling OEMs and Tier-1s to decouple vehicle functionality and features
  • Modularization of the hardware and software architecture needs
  • Helping partners remain profitable by enabling them to monetize the hardware, software and system integration solutions, services, and support
  • Simplifying audits, standards compliance, and quality
  • Creating newer business models in mobility
  Trends   Implications   Challenges Sasken is Solving
  Increase in adoption of AUTOSAR based architecture to reduce costs and time to market   Need to move to AUTOSAR based modular architecture for ECUs   Selection of AUTOSAR stack and components
  Emergence of Adaptive AUTOSAR in Body Electronics domain   Migrate event driven ECUs architecture to Adaptive AUTOSAR architecture   Transformation of ECU architectures with non-critical features
  Consolidation of ECUs to lower cost, simplifying OTA updates, and reducing power consumption and overall vehicle weight   Introduction of ECUs, DCUs, ZCUs, Gateways, Vehicle Central Computing Units (VCCUs) collaborating as cognitive control units with high degree of configurability and re-use   Virtual ECU development emulating peripherals
  Emergence of new in-vehicle communication technologies   Need to implement CAN FD, SOME/IP, DDS, RESTful, IPC communication   Selecting right technology choice for inter ECU communications
  New use cases in Body Electronics domain   Reducing Body Control module load and limited to critical functions   Using AI and Data Analytics to support new use cases, variant handling, and partial networking
  Increase in Safety and Security concerns  

Separation of critical and non-critical functionalities

  AUTOSAR Conformance, Functional Safety as per Development Interface Agreement and Cyber Security Compliance
  Stress on improving test coverage   Need to automate model-based development and testing   Finalizing test acceptance criteria
