So how is this done on cars? Dores each manufacturer have their own proprietary bus system (what i imagine), or is there a standard that everyone can use?
Protocols like CAN, LIN, SENT and XCP are all standardised point to point and bus protocols for automotive stuff
I personally think the standardisation is actually a bit limiting[1]
Just like SpaceX found massive cost savings in using networking tech over hard wired interconnects, I think there’s a good chance China or other manufacturers might catch on
[1]I think interconnect failure rates are so low out of factory it’s not unethical to begin making things more lean, obviously with sufficient human safety testing
But I’m not an expert, just a former engineer working in an electronics shop…
