"CAN FD barely makes the mark for 1080p video streaming at 60fps"
Maybe use CAN for what it was intended and add any new, proprietary high-speed video stuff on the side?
- Bluestein 2y agoThis. An extension or annex. Does every protocol needs to end up streaming video? Even industrial-grade stuff?
- fragmede 2y agoAh, yes, industry. A place where, famously, eyes aren't used because they're not rugged enough.
- Bluestein 2y agoHeh. That's what we need :) Ruggedized eyes.- PS. Wonder if such a thing exists in nature ...
- spwa4 2y agoIndeed. What's wrong with just sticking a usb-c hub in the cars for entertainment stuff? Oh and disconnect it from the vehicle control.
- Bluestein 2y agoRight? Or an optical network, just for that high bandwidth, "modern" stuff ... ... but for goodness sake, leave good enough alone for critical stuff.-
- detourdog 2y agoThe high speed bus should be optical.
- bayindirh 2y agoThey should mandate glass fibers.
- threeseed 2y agoThunderbolt 5 can handle a dozen 4K/30fps streams off a single copper cable. The limiting factor is the available compute not bandwidth.
- eqvinox 2y agoIt's not about bandwidth; combustion engines used to be massive EMI disasters (due to ignition coils) wrecking electronic communications in their immediate vicinity. Fibre optics are plain noise immune. Not sure how much of this is needed with high power electric motors. They're also lighter than copper cables, which can in fact matter in a car (though changing interconnect types and topologies also fixes that.)
- amalcon 2y agoElectric motors are - almost by definition - giant, fast moving magnets. That will generate current in any nearby wiring, and thus interference. That said, this kind of interference is much easier to filter than the kind you'd get from 4 to 8 spark plugs firing in sequence. So it's pretty likely that this is easier to deal with.
- r00fus 2y agoAre fiber optic cables flexible and tough enough? Fiber optic seems to be good for fixed deployments but not exactly fit for a rough&tumble environment like a car.
- eqvinox 2y agoShort answer: yes. Long answer: you need to choose appropriate connectors and fibre types. There's more to fibre than just OM5 and OS2 on LC connectors. Disaster recovery agencies as well as militaries use fibre cabling in temporary camp / communication infrastructure setups too, with ruggedized cables and connectors. There's 50+ years of history and experience to source from. "Counter" answer: copper cables in cars also break.
- bayindirh 2y agoNo no no... Like Cybertruck, they're doing something amazing, so we should let them do whatever they do without limits. (obvious angry satire warning if it's not visible already). Maybe they should add some efficiency in to the protocol, via their newly obtained cross-discipline expertise. And the protocol shall have no logging capabilities.
- Bluestein 2y agoOh, it should log.- To DOGE.- /s
- threeseed 2y ago> add any new, proprietary high-speed video stuff on the side Dashcams just use regular USB-C with HDMI or DisplayPort. And the electronics for this are cheap, plentiful and reliable since it is used extensively in hobbyist circles e.g Raspberry Pi. No need for anything proprietary or crazy. Just run another cheap cable.
