Hi,
even though I'm pondering buying a capacitive wheel, I had time to test some settings regarding travel assist with my Leon.
So activating capacitive wheel without one definitely doesn't work. It creates an error (as said in an other forum), though interesting enough, it seems the only thing necessary to really activate TA.
Indeed, I tried activating it with HC variant 0 > ACC error, HC variant 1 > ACC error (see more later about that), HC Variant 2 > TA Assist Error (see more later about that) with the TA icon appearing.
So it seems that even with manual gearbox, TA assist can be activated having the right hardware.
Now, I learned a few things trying HC variant 1 and 2 without activating the capacitive wheel:
HC variant 1: in fact, it makes the ACC behave like TA assist. I've set it at 30km/h to test > the ACC activated and also the line assist came up with early setting (automatic yellow lines) keeping the Leon in the middle of the road. So I guess it's the setting for the pre-TA system that were available on older VW group cars (maybe adaptative lane assist guidance or something like that)
To note that lane assist will not, normally, activate under 55-60km/h, so that's definitely TA-like.
HOWEVER, you still get the "please take control over the vehicle" every 10 seconds if you dont move the wheel (funny enough, if the vehicle has to correct trajectory, it will cancel the warning, so it's really a basic "move the wheel so we know you're in control" as even the lane assist system will shut down the warning).
HC variant 2: does not do anything at all different than default settings. ACC activates and lane assist begins at 55-60km/h and stays set to late (so you bounce from one side of lane to the other). Funny to note, it didn't take into account that I had disabled the "stay in the middle of lane" message and as far I've tested it, it didn't trigger the "takeover" warning.
It seems in line with the fact that everything went to green with HC variant 2 when Zoidberg installed the capacitive wheel on his car.
Now, there's one more thing I coded in hopes of removing the "please take control over the vehicle":
In long coding of unit A5, I disabled "HC advanced takeover request" > it had no influence on HC variant 0 and 1, I still got the warning.
On HC variant 2, the consequences are more complicated to comprehend. As said above, it seems it overruled my setting to disable the "stay in middle" message and did not activate the "takeover" warning. So it may, and I say may, be able to get rid of the warning for people with capacitive wheel. Again, it's just a BIG speculation on my part.
That's it.
Anyway, the end results of all this is that I cannot, and maybe forever, find a modification to remove the fateful "please take over control of the vehicle" warning although HC variant 1 leaves the door open to actually have travel assist without a capacitive steering wheel.
So if you guys got any idea, that would be welcome.
