Abstract
New generation electrified and self-driving vehicles require much higher
performance and flexibility for onboard digital communications than
Controller Area Networks may offer. For this reason, automotive Ethernet
is often regarded as the next de facto standard technology in these
contexts, and by extension for networked embedded systems as well.
However, an abrupt and drastic move from CAN to Ethernet is likely to
cause further cost increases, which can be hardly tolerated by buyers.
This paper analyzes the third generation of CAN, termed CAN XL, and
studies how interoperability can be ensured with Ethernet. Likely,
composite CAN XL-Ethernet networks are the key for getting the best of
both worlds, not only in the automotive domain but also for sensing and
control in scenarios like building automation, wired sensor networks,
and low-cost networked embedded systems with real-time constraints.
