Doing an automotive ECU, any good EE reference documents or standards?

Going to do ECU for work and is looking for any good reference literature or standards that need to be followed.

Right now I’m wondering if isolation of power and communication is used or not as a general rule. Hard to find good information on Google. Any industry go-to references for automotive electronics. It will have options for both CAN and LIN.

That is going to be a fun task to learn all that. Are you really that sure that you want to go down that route as it's not easy to get your head around all the legal stuff you have to do.

I spent some time around the types that develop ECU stuff, injectors and those that the type approval stuff. They are all rather special and make TEA members seem normal.

I guess first thing your employer who wants to get into automotive electronics without any prior experience (???) should do is to get a consultant on board. TÜV Süd or DEKRA offer consultancy services and can advise you on all standards that apply and any certifications your company might need before even starting such a project.

David Hess:
I remember seeing reference designs from the companies that sold the microcontrollers used in ECU, chiefly PowerPC at the time.

Hello,

ECU = Engine Control Unit / Electronic Control Unit ?
So combustion engine or electrical vehicle?

How much power? (current, frequency, rise time?)

The general rule will to keep it as cheap as possible (in series production). So you will have many re-designs until the power stages do no longer interfere with communication.

Every OEM has its own standards.
And those are usually harder to be fulfiled as the industry standards.

with best regards
