I'm not clear on it either, but I think it's some kind of cruise-control, with auto-steering. (If I'm wrong, someone please let me know)
How about"copilot"?
MagiControl?
CoPilot? Someone who can completely take over for you when you're feeling tired. Compared to an Autopilot which requires pilot or skipper supervision I think copilot would be a far worse term if it weren't for the fact that the name doesn't really matter too much.
