  1. Technical session 3: ITS-Networking, architecture and protocols Summary and next steps Session Chair : Denis Griot Freescale

  2. 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 Helge Zinner

  3. Highlights from Continental Presentation„Network and configuration management“ • Integration of SNMP into an Automotive Environment • Examination of different approaches to network configuration • Research on algorithms which allow dynamic reconfiguration of the system • Analysis of energy saving capabilities • Realization of an experimental model network for concept evaluation Norbert Balbierer

  4. Highlights from I.I.T. Delhi “Development of open-core Flexray controller for OEM ultra low cost Automotive” • 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 • 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 PRAMOD.VSUBRAT KAR

  5. Highlights from FreescaleEvolution 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 Marc Osajda

  6. Highlights from Telcordia « 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 Ratul Guha

  7. Highlights from INRIAThe 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) Thierry Ernst

  8. 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 Denis Griot

  9. 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 approach to ensure interoperability Denis Griot
