I would not do it until you get the necessary information. The OEMs I worked with took maybe 5 years to design a module, qualify it, test it, spec it, build prototypes, then pre-production. They have experts in every aspect of automotive electronics and thousands of years of combined experience on the teams. I very much doubt it you have the facilities available to properly test this. Have you ever done a FEMA (Failure Effects Mode Analysis) and the twenty or more other processes it goes through to qualify? For a simple read downlaod STs AN2689 "Protection of automotive electronics from electrical hazards,
guidelines for design and component selection" Have fun it will be an expensive endeavor to do it properly and safely. If this goes on the road you have a lot more to do.
Isn't it FMEA?
You can buy can bus looms and controllers fit race cars - that’s the way to go .
Not a project even for most advanced users , huge task .
Depends on the company, I have seen both. It reminds me of the old days which way did you turn the handle to raise the car window? I was thinking of mentioning PPAP (Production Parts Approval Process) and the associated costs.
