The before/after ECU layout diagram is very instructional.
I like to imagine some kind of engineering “meet cute” whereby, one random day, the headlights engineer and the parking radar engineer happen to be working on the front of the car together. Their eyes meet:
“hey, I’m John — I didn’t know you had an ECU here!”,
“hi, I’m Claire — wow, you have an ECU right up front too? It’s, like, right next to mine and we never knew!”
“I know, crazy right?! Hey this is going to sound really forward and I don’t normally do this but I’m only running at 70% compute capacity. I don’t suppose you need any real-time budget this evening?”
“So funny you should ask, I was just about to run a whole bunch of heavy new wiring to…”
And in a story as old as time they get ECU married and raise their control loops in the same front-of-vehicle ECU together instead of living their separate, lonely, ECU-right-next-to-each-other-and-they-didn’t-know-it lives.
