2nd Ethernet & IP @ Automotive Technology day
The Next Generation Automotive Network The Next Generation Automotive Network --
Updates of the related activities in Japan Updates of the related activities in Japan --
Brief History of Brief History of TMCTMC’’ss Ethernet DevelopmentEthernet Development
Developed ““Automotive EthernetAutomotive Ethernet”” that supports ““FailFail--safe functionssafe functions”” and ““RealReal--time featurestime features””
• Research on Residential Ethernet for in-vehicle networks• Evaluation of Ethernet AVB standardized in CE
– Simultaneous transmission of audio and video streams
• Enhancement required for automotive networks– Recovering from failure
Up to several tens seconds for recovery from failure ⇒⇒
Difficulty in failDifficulty in fail--safesafe (Inapplicable to automotive)
– Best effort communications No guarantee of latency time (Standard Ethernet)
⇒⇒
Difficulty in realDifficulty in real--time communicationstime communications (Inapplicable to control systems)

ConclusionConclusion Contributing our requirements to global standardsContributing our requirements to global standards
1.1. Automotive EthernetAutomotive Ethernet– Importance of fail-safe functions and real-time features– Proposal to AVB to be added as Automotive profiles
2.2. Architectures for Ethernet Bus SystemsArchitectures for Ethernet Bus Systems– Suitability of Ethernet applications for in-vehicle networks – Consideration of multiple protocols handling and security
3.3. Ethernet Activities for Automotive Use in JapanEthernet Activities for Automotive Use in Japan– JASPAR “Next Generation High-Speed In-Vehicle Network”
Working Group – Established this April– WG to define automotive requirements and to liaise with
other existing standardization bodies for global standards
