Automotive Ethernet for vision-based ADAS: Loss, cost, and latency


Delphi Wire HarnessEmbedded Computing Design published an article with our own Marco Jacobs, talking about automotive ADAS, the adoption of Ethernet and its implications. We’re reprinting the first few paragraphs here. The full article can be read on the Embedded Computing Design website.

Automotive Ethernet is slowly but surely making its way into next-generation vehicle designs, but increasingly those designs also include advanced safety systems that require minimal latency. For the camera systems associated with these advanced driver assistance system (ADAS) functions, the image buffering, encoding, and decoding requirements of Ethernet could potentially have negative consequences on these real-time systems, despite the technology’s increased bandwidth.

In this interview with Marco Jacobs of IP vendor videantis GmbH, we discuss the pluses and minuses of Ethernet, and explore video codecs and alternative architectures that could compensate for concerns around using automotive-grade Ethernet in active safety applications.

How much interest do you see Ethernet garnering in the automotive space, particularly as it relates to active safety or advanced driver assistance system (ADAS) functions?

JACOBS: Broadcom started with this automotive Ethernet standard called BroadR-Reach several years ago, which has since been standardized as IEEE 802.3bw 100BASE-T1. BMW was one of the first car companies to pick it up. The automotive industry is a little bit slow, but the use of Ethernet is now rapidly growing. We see several original equipment manufacturers (OEMs) now using Ethernet for different purposes in the car.
