For over 15 years, Felix Ottofuelling has worked in the testing and validation of in-vehicle networks and ECUs based on CAN, CAN FD, LIN, FlexRay and Automotive Ethernet. His experience covers testing individual ECUs on test benches and complete vehicles during fleet testing with high-end data-logging systems.
His current focus is the fundamental transformation of in-vehicle network architecture from domain-based to zonal networks, including the design of zonal architectures for software-defined vehicles based on Automotive Ethernet.

All-Ethernet E/E Networks – Zonal Architecture for SDV: Why 10BASE-T1S Is Replacing Legacy Bus Topologies
Automotive Ethernet is the enabler for zonal networks. However, the high gigabit bandwidth used between high-performance computers and zonal controllers is not required in every area. Zones containing peripheral actuators, sensors and other components require much less bandwidth. For these applications, the 10BASE-T1S physical layer can be used.
The presentation explains how a 10BASE-T1S network differs from other Automotive Ethernet technologies and how it supports bus-type architectures similar to CAN while retaining the benefits of Automotive Ethernet protocols. It also shows how 10BASE-T1S can replace CAN FD networks and support an all-Ethernet vehicle architecture.
What the audience will learn
• Why Automotive Ethernet is important in zonal architectures.
• How software-defined vehicles are built on zonal networks.
• How in-vehicle network topologies are changing.
• How 10BASE-T1S networks operate.
• The benefits of replacing legacy networks with Automotive Ethernet.
