In this reference design, the TCU delivers vehicle telematics from the edge to the cloud. The TCU acquires data from multiple simulated subsystems (for example ADAS and GNSS). The TCU acquires the data from CAN/CAN-FD and Ethernet sources and propagates data to the cloud using fit-for-purpose mechanisms. The fleet operator UI can manipulate/throttle TCU to cloud throughput. The TCU uses fit for purpose mechanisms to deliver telematics data from the edge to the cloud securely, resiliently, and efficiently.

The demonstration uses the GATS, AEM/AEMP, ASAM, and ISO 15638-21:2018 telematics standards where applicable.
Reference Design Storyboard
This story board walks the evaluator through the expected experience when operating the reference design. It also acts as a story for delivering the demonstration to evaluators for live or recorded events.
Device Commissioning and Provisioning
How the device "turns on", starts operating with the local network, how it joins the upstream operator network.
Device throughput for local operation
Although the local device during normal operation would be headless, the demonstration has local output that demonstrates to the user the throughput for incoming data, how the TCU operates on that data, and then the "drop rate" or "sampling rate" or "aggregation rate" of data going to the cloud.
Cloud operator experience
After the local TCU shows to be operating properly, turn to a web console that
