ADI signs BMW for 10BASE-T1S Ethernet to the edge

BMW is to adopt the 10BASE-T1S Ethernet to the Edge bus technology developed by Analog Devices (ADI) in a key partnership.

ADI’s E²B 10BASE-T1S transceivers will be used by BMW for ambient lighting systems in future vehicles and opens up the development of software-defined vehicles.

In-cabin experience continues to be a critical focus for automakers, with driver and passenger expectations becoming more refined. This is especially true of the ambient lighting within the vehicle.  

However, many lighting designs can be complex to implement, use legacy technologies, and are difficult to scale and update as the number of supported LEDs increases. Using 10BASE-T1S with E²B technology allows developers to synchronise the lighting with other applications in the vehicle. A fully software-defined lighting system provides improved flexibility, ease of upgrade, and ease of use. 

ADI has been working closely with the BMW Group since 2018 on the E²B technology to bring Ethernet to the Edge while the IEEE802.3cg Group was defining the 10BASE-T1S standard.

Using ADI’s 10BASE-T1S E²B technology allows BMW to remove microcontrollers and move software from edge nodes to central processing units to create all-hardware edge node while reducing software development and qualification tasks.  

 “While working alongside ADI on 10BASE-T1S E²B, we joined efforts on a number of key considerations, from simplifying implementation, to cost analysis and design support. The relationship with ADI has enabled us to move more quickly to market with a solution of a zonal architecture for software-defined vehicles,” said BMW. 

  “We continue to deeply engage with the BMW Group to understand their next-generation needs and bring further optimised products to aid next-generation architectures, as well as bring continued cooperation on standardisation,” said Yasmine King, Vice President, Automotive Cabin Experience at ADI. “10BASE-T1S E²B is a great new addition to our automotive connectivity and networking portfolio, innovated to drive success across different use cases, with the flexibility and scalability to support zonal, domain and hybrid architectures.”  

“This approach to edge connectivity is so sought-after that the automotive industry inside the Open Alliance (opensig.org) is now aiming to standardise a similar solution. ADI, along with the BMW Group and other companies, are actively working with the industry to create an Open Standard implementation,” said King.
