Paddle Shifting (for MT) - Toyota Yaris Forums

Tamago · 11-17-2008, 04:13 PM

good afternoon everyone..

i am in the process of building a paddle-shift system to be used on any manual transmission that utilizes cables for shifting. the system will utilize two pneumatic cylinders with positional feedback switches, 4 three-way pneumatic valves, a PLC, a small air compressor and tank, and switches mounted either to a sandwich adaptor (for aftermarket 6bolt steering wheels) with paddles integrated or limit switches to be mounted under the shifter to sense fore-aft motion. i currently predict this kit to sell for around $1000..

anyone interested?

mikenacarato · 11-17-2008, 04:21 PM

well it definately sounds awesome! i am more of the normal manual shift type but for those who want paddles its your chance! :)

Tamago · 11-17-2008, 04:23 PM

fyi your clutch will be fully functional (and required) and i will integrate a small air cylinder to blip the throttle on downshifts..

mikenacarato · 11-17-2008, 04:49 PM

thats cool. but can you retain the stock shifting mechanism for street driving if you choose?

cali yaris · 11-17-2008, 05:19 PM

Looking forward to pics and a review of your prototype

This would be cool as sh*t

Mini also has a system like this you might want to check out for ideas and whatnot... looks promising..

would they work in AT? i got confused by the website selling em for Automatic?

Cheers

that website makes me sad..

first, it's only for transmissions with the stick ON the trans (RWD setups)

second all they show you is pretty pictures of the paddles.

here's my work so far

my initial design will be for MT only.

here's my chicken scratches from last night..

and my truth table.. gotta integrate this into the programming now.. my brain hurts

i1-i4 are cylinder position feedback inputs (so the PLC knows what gear you're in)

i5 is "upshift" input from the paddles
i6 is "downshift" input from the paddles

Q1-Q4 are outputs for the valves that will control the cylinders

well, I'm certainly interested in the technology behind it, it is an awesome project, too bad you can't integrate the clutch

i personally would HATE to lose my clutch..

eTiMaGo · 11-18-2008, 08:54 AM

well doing it as a clutch override would be ideal I guess, so you retain normal control of it. Seeing as it's a hydraulic setup (at least on our cars, not sure about the xA), it should be possible given the right engineering? Or maybe as a future upgrade

entirely possible. this unit will most likely have a throttle blip on downshifts.. to do clutch you integrate a large number of things and will require a plc that costs about triple of the little Siemens unit i'm using (6 inputs, 4 outputs)

eTiMaGo · 11-18-2008, 09:04 AM

all right, gotcha

it'll still be pretty awesome as you are planning it!

if you take away the clutch, you might as well have a automatic.

Tamago · 11-18-2008, 03:50 PM

well, i just finished the PLC program.. i know a screenshot is pretty useless, but this is what 7 positions look like (1-5 + N + R) and what it takes to cycle through all of them.

i'm not gonna mess with the program anymore until i get all the components here.. checking the interlocks without physical movement is making me go cross-eyed

Tamago · 11-20-2008, 11:04 AM

i modified a stock shift cage to only go forward and backwards.. will mount this guide plate in place with a spring load to keep it centered, then limit switches will be mounted on the other side of the plate
