Enhanced Automotive and Safety Systems
TSN (Time Sensitive Networking) adds guaranteed latencies for automotive control functions & the ability to build redundant network paths for safety-critical communications. Excelfore AVB/TSN is AVNU certified, so you also get interoperability with other certified AVB/TSN devices.
Scalable Network Bandwidth and Dynamic Switching
Ethernet enables cost-effective in-vehicle bandwidth scaling from 10MB multi-drop to 10GB and beyond. It also brings dynamic network switching, network security and the ability to reach devices from the Cloud.
IP Addressing and Accessibility for CAN Buses
SOME/IP, DoIP, RTP, RTCP and UDS protocols from Excelfore bring your legacy systems forward into the age of the Software Defined Vehicle, integrating seamlessly into an Ethernet backbone to provide full cloud accessibility to your CAN based devices.
