This article will be gift for all of us as new year 2021 coming.

Happy new year, and thanks for all of us the innovations, devotion for vehicle industry safety and security development.

This article will introduce SOA based EE architecture, and then try to list out tyical ECUs itself functional safety and cyber security classifications, ASIL level, SOTIF FMEDA value, and CAL value. Finally to introduce all ECUs themselves mapping to EE architecture physical distribution...

First: zonal EE architecture introduction

Visteon had put forward one model for zonal EE architecture introduction as following:

Visteon had put this architecture as SOA based, they have following advantage and applications:

Abstract from physical to logical connections
Services availability throughout the IP-based network
Well-established experience from other industries are applicable
Legacy communication mechanisms will remain
Mission critical ECUs (e.g. ESP) using signal-based communication
Services can be mapped on legacy ECUs, e.g. using Classic AUTOSAR
Novel functions without changes on ECUs and on wiring harness
Decreased topology complexity
Increased potential of wiring optimizations

First: Typical ECUs safety and security classification

So here, based on inputs and regulations following

ISO 26262,
ISO 21448
ISO 21434

拿细耳人不倒翁，公众号：智能网联车安全SOTIF FMEDA

we can derive out the following important overall view of 77 typical ECUs functional safety and cyber security classification, for detail guidance, or why the ASIL, CAL, SOTIF FMEDA like that, please contact me ASAP if questions.
