Highlights from Continental Presentation
“Real Time Ethernet for Automotive”
Ethernet AVB provides Quality of Service necessary in
the vehicle
Ethernet AVB provides similar costs to standard
Ethernet
Current activities:
Integration of AVB in Automotive ECUs
The authors recommend to use standards
Research on QoS model for different data
transmission
Evaluation of enhancements and modifications of AVB

“Development of open-core Flexray
controller for OEM ultra low cost
Automotive”
o
o
Vehicular networking will play a major role in the future
automobile
As a vehicular networking protocol, Flexray will ease
implementations like “Steer by wire”, “Brake by wire” in
future automobiles
o
o
Open-source silicon will be to automobiles what open-source is to
software. Boundaries will end, monopolies will cease.
Smart Flexray controllers will help in managing the data
flow in a vast Flexray network and bringing down the cost
per ECU

Highlights from Freescale
Evolution of Automotive In-Vehicle
Networking
Vehicle E/E Architecture is becoming overcomplicated
Domain controller vehicle E/E architecture is the new trend
Need for high computing power
Need for high bandwidth network:
FlexRay in the chassis/safety domain
Ethernet in the infotainment/Diagnostic domain
Need for centralized gateway
Centralized Gateway is needed to provide the necessary
interface to C2C & C2I solutions
Increase computing power, increased software content,
increase complexity will drive the demand for functional
safety: ISO26262
Safety standards are becoming the key enabler for the
design of all new electronic application in the vehicle

« Context-Driven Disruption Tolerant
Networking for Vehicle Applications”
Overviewed general DTN approaches
Proposed a context-driven DTN (C-DTN)
that supports networking in
consideration of application context
needs
Evaluations to validate C-DTN
dissemination performance with realistic
mobility
Diversity in mobility pattern generally improves
performance
Under correlated mobility model, DTN dissemination
performance depends on a number of factors

The GeoNet project:Combination of IPv6 &
GeoNetworking
IPv6 + GeoNetworking = Enabling technology for better:
Road safety
Traffic efficiency
Value added services
Well supported at time of set-up
C2C-CC, SafeSpot, Coopers, CVIS
Status
1 reference specification
2 prototype implementations (Linux 2.6 / UMIP)
Experimentation on a fleet of 4 vehicles
Conformance tests: TTCN-3
Emulation with NCTUns
CVIS selected as the target platform
Effective dissemination in SDOs (ISO, ETSI, IETF)

Session 3 : Conclusions
Rapid evolution of in-vehicle networks towards higher
bandwidth and functional safety
The gateway ECU functionality will expand as V2V
V2I deployment kicks off in 2013
Real time Ethernet and fault tolerant protocols –
Flexray – will co-exist
EVs, PHEVs, ultimately all vehicles will be compliant
to ISO26262
Context driven disruption networking (C-DTN)
guarantees high QoS, a demonstrator will provide the
proof of concept
GeoNet will enable position aware applications, IPv6
will be mandatory

Session 3 - Recommendations to the
Standards Defining Organizations
1. Concretize the ISO/ITU-T joint
working group for the standardization of
the in-vehicle networking architecture
and protocol
2. Support System Level standards
