Clutch By wire
Discussion
Sorry, but you simply aren't going to find out any specifics on this one on a website, even one as well resourced as PistonHeads. Google it, and you'll still only find the bare details. This is because the people developing these systems have spent a lot of money doing so, and are not just going to publish how they did it.
Having said that, my suggestion would be to start at first principals, and model a conventional clutch (pick your favorite simulation environment, i'd suggest Simulink if you want to eventually run MIL or HIL tests) and then see what you need to do to control the torque transfer. However, what you will quickly find is that the factors that are difficult to accurately model, like friction, wear, fundamental frequency oscillations etc make a huge difference to the way a real clutch operates. You've only got to drive one of the first single clutch automated manual transmission, like say a Gen1 AML Vanquish to see just how difficult ;-)

Just looking at the articles on the Bosch eClutch, and it seems the number one advantage being touted is that it prevents "embarrassing stalls". These are mainly US-centric articles as far as I can tell, so does this mean most Americans use a conventional clutch with the finesse of a rabid baboon?
Hello to you both, Yeah it has been a pain modelling the e clutch. But i am stuck in MATLAB while modelling the Shift in Progress state. Rest i have created a clutch manager that can do the work.
And yes bosch eclutch is also a good source to study, but they havent yet declared the technical details.

Coming from a land of automatics...some, or many seem to revel in their abilities to "shift gears"America also seems to have a hell of a lot of faulty clutches too when you read various performance forums.
So I think there is much merit in your last comment lol.
