[Going to give myself a self-reply here, but what-ev's. This is how I talk to chat-gpt, FYI]... So I happened to be shopping for a cheap used car recently, and we have these ~15 year old Ford SUV's in Aus that are comfortable, but heavy and thirsty. Also, they come in AWD and RWD versions. So I had a thought bubble about using an AWD "gearbox" in a RWD vehicle whilst connecting an electric motor to the AWD front "output", so that it could work as an assist. Here was my first question to chat-gpt about it; > I'm wondering if it would be beneficial to add an electric-assist motor to an existing petrol vehicle. There are some 2010 era SUV's that have relatively uneconomical petrol engines, which may be good candidates. That is because some of them are RWD, whilst some are AWD. The AWD gearbox and transfer case could be fitted to the RWD, leaving the transfers front "output" unconnected. Could an electric motor then be connected to this shaft, hence making it an input? It gave a decent answer, but it was focused on the "front diff" and "front driveshaft" and stuff like that. It hadn't quite grasped what I was implying, although it knew what it was talking about! It brought up various things that I knew were relevant (the "domain knowledge" aspect), so I brought some of those things in my reply (like about the viscous coupling and torque split); > I mentioned the AWD gearbox+transfer into a RWD-only vehicle, thus keeping it RWD only. Thus both petrol+electric would be "driving" at the same time, but I imagine the electric would reduce the effort required from the petrol. The transfer case is a simple "differential" type, without any control or viscous couplings or anything - just simple gear ratio differences that normally torque-split 35% to the front and 65% to the rear. So I imagine the open-differential would handle the 2 different input speeds could "combine" to 1 output? That was enough to "fix" its answer (see below). And IMO, it was a good answer! I'm posting this because I read a thread on here yesterday/2-days-ago about people stuggling with their AI's context/conversation getting "poisoned" (their word). So whilst I don't use AI that much, I also haven't had issue with it, and maybe that's because of that way I converse with it? --------- "Edit": Well, the conversation was too long for HN, so I put it here - https://gist.github.com/neRok00/53e97988e1a3e41f3a688a75fe3b8bcd https://gist.github.com/neRok00/53e97988e1a3e41f3a688a75fe3b...
