The SH-2 processor used on the Sega Saturn apparently is used in engine control units. I used to work on a space-rated system that used radiation-hardened Xilinx processors/FPGAs.
A lot of commodity electronics have variants intended for harsh environments (eg. radiation, extended temperature). Though it's not simply a matter of taking a consumer-grade design and changing a few part numbers and now you have something you can launch into space or put on a fighter jet. You have redundant components with redundant voting, special enclosures and coatings to deal with harsh environments and all kinds of other "fun" stuff.

Yeah, it's not a direct PS1 part, but it's the basis.
