Automotive SDN Architecture for enabling SDV

Mr.Tatsuya Izumi
Team Leader, SDN Study & Verification Team
JASPAR Next Generation High-Speed Network WG
JASPAR (Sumitomo Electric Industries)

Profile

He started his career from research and development of in-vehicle communication and architecture, and in recent years has been engaged in network products development including automotive Ethernet. He is also a member of JASPAR Next Generation High-Speed Network Working Group from 2016. He leads the SDN Study & Verification Team from 2023.

Even after the SDV is supplied on the market, the vehicle evolves due to additions and changes in the software. Therefore, an innovative in-vehicle architecture with flexibility is necessary to add or change functions through software, allowing the in-vehicle network to realize functional additions and changes. JASPAR is studying applying the SDN (Software-Defined Networking) concept to in-vehicle networks and defines this as automotive SDN. SDN is a system that can dynamically update network configuration in the ICT field. For SDV, this presentation proposes a new in-vehicle architecture to realize a network that applies automotive SDN. Specifically, we define the minimum requirements for in-vehicle SDN based on use cases and define the prerequisites for an in-vehicle network, proposing a reasonable logical and physical architecture from the viewpoint of these constraints.

Vice Chair, JASPAR Next Generation High-Speed Network WG
JASPAR(Honda Motor)

Profile

Takumi Nomura is the vice-chair of JASPAR Next Generation High-Speed Network Working Group and a Chief Engineer of Honda Motor Co., Ltd. He received his PhD in Engineering from Kyushu University, Japan. Before joining Honda, he was engaged for 15 years in research on applied technology of Ethernet. His current research interests include the next generation E/E architecture and automotive Ethernet technologies.

With the spread of in-vehicle Ethernet, IEEE and multiple organizations, such as AUTOSAR, OPEN Alliance, and AVnu Alliance, have started developing standards. Unfortunately, the conflicts that cause various harmful effects can naturally arise among multiple standards. Against this background, this presentation introduces some conflicts between standards and examples of JASPAR’s effort to solve them. Finally, the presenters want to call on the audience to ensure that various standards cooperate.

Ethernet @ BMW 2023

Dr.Kirsten Matheus
Senior Expert for In-vehicle Communication Technologies
BMW

Profile

Dr Kirsten Matheus is engineer and economist. Since 2003, she has worked in the automotive industry; since 2009 at BMW. At BMW she is responsible for the strategy for the in-vehicle networking technologies. This entails ensuring the availability of suitable in-vehicle networking technologies well before application engineers want to use them. In this context she successfully introduced Ethernet as a networking technology into the automotive industry. In her opinion, only open standards provide the basis for long term sustainability of networking technologies. She and her former colleague Thomas Königseder describe their experiences, background and technical concepts behind the use of Ethernet in the automotive industry in a book titled “Automotive Ethernet”. Her new book, co-authored by her colleague Michael Kaindl, “Automotive High Speed Communication Technologies, SerDes and Ethernet for Sensor and Display Applications”, appeared in Autumn 2022.

In 2023, BMW is looking back on 15 years of experience with Ethernet in series production cars. During this time, BMW has continuously extended the number of Ethernet nodes as well as the functionality of the Ethernet network in its cars. This refers to supported data rates as well as to supported networking capabilities (security, diagnostics, …). Looking forward, BMW intends to further extend its in-vehicle Ethernet network. This presentation elaborates on the architecture induced changes (“zonal”) and the challenges and solutions this offers. The extension to lower data rates (10BASE-T1S) as well as higher data rates (MGBASE-T1 as well as ASA-ML) each have different implications that will be discussed in detail.

Functional Safety (ISO 26262) in In-vehicle Ethernet
～JASPAR Analysis results ～

Dr. Yasuhiro Yamasaki
JASPAR Functional Safety WG Communication Team Leader
JASPAR(Toyota Motor)

Profile

After Dr. Yasuhiro Yamasaki engaged in research and development of communication technology in the ICT field, he has participated in the development of in-vehicle Ethernet technology.　He currently engages in in-vehicle communication safety (functional safety and quality of service (QoS)) and advanced technology development (Ethernet AVB/TSN and SDN). He is the JASPAR Functional Safety WG Communications Team Leader, a researcher at the Kwansei Gakuin University. He works for Toyota Motor Corporation.

This presentation introduces the method/concept of supporting the functional safety standard (ISO 26262) in In-vehicle Ethernet. In-vehicle Ethernet is expected to be used more widely in the future. On the other hand, due to the complex protocol structure and the use of OSS (Open-Source Software), it is difficult to take conventional functional safety measures (functional safety measures are implemented for all communication elements). In this presentation, we will introduce functional safety measures that incorporate the concept of black channel, which can also be applied to In-vehicle Ethernet.

He is a member of the Next-Generation High-Speed LAN Working Group at the Japan Automotive Software Platform and Architecture (JASPAR) and also serve on the organizing committee of the IEEE Ethernet & IP @ Automotive Technology Day.

The development of autonomous driving technologies and SDVs is accelerating, and there is a need for faster, real-time communication. As a result, the range of applications for automotivee Ethernet has expanded, and communication speeds have evolved from 100Mbps to 1Gbps and then to multi-gigabit. However, in order to accommodate such high-speed communications, the Electronic Control Unit (ECU) design increases in difficulty in terms of SI(Signal Integrity)/PI(Power Integrity)/EMC(Electro-magnetic Compatibility). In this presentation, ECU hardware design and EMC performances for multi-gigabit Ethernet are explained.
