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
