3Vehicle E/E Architecture Challenges
o Too complex, too much energy consumptiono Too many different networkso Too many ECUso Too many cableso Too many connectorso Too much weighto Too many too many…
With further electrification of the vehicles, A global rethinking of the vehicle E/E architecture
is needed

5Architectural Evolution – Ethernet in Automotive
o Well known technology, Widespread knowledge, Wide availability of tools
o Ethernet can handle future bandwidth requirements for multiple in-vehicle application
o Unshielded twisted pair Ethernet based network significantly reduces cost
o Unified Ethernet architecture eases diagnosis and maintenance
o Ethernet AVB audio profiles can substitute synchronous MOST
Why Ethernet in Vehicles ?

8Functional Safety
oProvides and automotive specific risk based approach for determining risk classes (ASIL)
oSpecify the necessary safety requirements for achieving an acceptable residual risk
oProvides confirmation to ensure a sufficient level of safety is being achieved
Objective of the ISO26262 Standard
The Fully Networked Car Geneva, 3-4 March 2010
9Functional Safety / ISO26262
o Functional safety is a key paradigm of next generation electronic vehicle systems
o Safety standards are becoming the key enablerfor the design of all new electronic application in the vehicle and associated semiconductor development
