electromechanical P-R-N-D development HELP!!!
OK, guys, I need some help on this one.
I need to remove my shifter from my console completely, I have things that would be better use of the space, I want to build a custom console that houses the display & control for my audio processor as well as a central command style control section with like a dial & several buttons around it for pc control like an i-drive or me/be type setup & I need to keep space for 2 cupholders so the shifter just has to go
I've always loved the mercedes electric shift, uses a stalk oposite the turn stalk thet you just push up for reverse, down for drive, push in for park, etc... when ever I want to manually shift I do that now with my paddle shifters already, so having a mechanical shifter is something I wouldn't miss one bit.
I don't necissarily need to have the stalk type setup, actually I think ideally though control would be best if there was an input for each gear selection by the push of an individual button, so any gear can be one push away, but I'm not opposed to the alternatives, which could be a potentiometer that sweeps through a range such as a servo control or worse case even a paddle type up/down setup, kinda like an electric ratchet shifter, to go from park to drive would be 3 taps down to r then n then d.
I am determined to do this but I have very little electronics knowledge as far as programming a pic or figuring out a way to do logic control, not enough to build an electronic control or something that would be able to sense position & make appropriate adjustments from different inputs or anything like that, my original idea to do this completely with just the knowledge I have was to convert my existing mechanical shifter to a real mechanical ratchet shifter, so at least I can electrically control it with just an up or down action, which could be done with a motor not too difficultly, then burry this whole ratchet shifter with motor & leavers attatched to it somewhere.
I even got as far as buying a B&M ratchet shifter & a 12v drill for it's motor & clutch, but then, I step back & look at what I'm doing & realize, I'm really kinda doing it the caveman way. I mean I'm pretty sure I could get it to work, but there are so much better ways to do this, so this is why I turn to the forum, for help & ideas as to how I could control something like this... what kind of a motor I could buy that would be appropriate for position control & how I could control it. linear actuator? great, I can hook it up, but how would I control it through the gears?
the actual gear shift movement is a shaft that rotates, there is a lever that comes off of the shaft. it needs to move an equal amount for each progression through the prnd range. fabrication is not a problem for me & I could fabricate a position sensor into this no problem but I don't even know what to do with a position sensor electrically... any help would be greatly apreciated with this project...
