Then the PSU unit of that single, central mini-server smokes and poof, everything from ABS to window controls stops working. That's really not nice.

What automotive designers have now is a mess, but it's a redundant mess.

Nicely explained, Larry. Thank you.

Integration ois different a clear trend among subsystem vendors, even though not exactly a single "all-in-one" system mentioned by prabhakar_deosthali.

Virtualization of processors, storage and now networking has been one of the biggest trends in computing and comms fr the last several years.

Embedded has been playing catch up. Intel pushed some of its tech this way a year or so ago. I believe other embedded OS vendors have too, but its still early days in the sector.

It is very tempting to think that, but the reality is that cars are becoming complex interconnected systems. The mode of operations has for many years been brute-force implementation of individual subsystems with minimal coupling between them. Implementing a hundred of these separate subsystems at, say, $10 each adds $1,000 to the BOM for a car. Replace that with a higher-capability shared subsystem that does all of it for, say $100, is a clear win.

It can also be a win technically. In individual subsystems any interaction between subsystems requires foreplanning and direct connectivity. With centralized resources interconnectivity becomes a software decision that can be made differently in later releases, without hardware changes. Think of it as a mobile SDN.

I've been told that they've been avoiding a single and central system to avoid having a single point of failure. I don't know how much weight I put in this, but I guess it makes sense.

So may microprocessors, so many interconnects, so much multiplicity of operating systems - just to drive a car!

Why can't somebody put a kind of just a single mini-server to do all those jobs without creating this jungle of processors , their memories , their peripherals and the mesh of  CAn , LIN, TCP/Ip and all that.

A robust single processor system should be able to minimize this whole mess to a reliable real time embedded system handling Engine control, Navigation, multimedia, ABS, Parking assistance and whatever you can name .

 

Just  a wild thought!
