I cant search much at work, but there are a few videos of it including lots of information (in Japanese) about the operation of it - and one with Kazama who has a go of it as well. Though i dont know what might be available in English so it might be hard to find information on it, not to mention they might have different rules as well meaning some of the gear installed may not even be allowed here.

FF&R September 09 Page 30 has a nice Datto 1600 setup for hand controls. They are all levers.

You will need to seriously talk to an engineer before embarking on electronic controls though, they are fraught with danger, and it takes quite a bit to get an electronic system certified for things like brakes and accelerator (though if it were factory there is no harm in moving the controls).

Was it black with an SR20 and in NSW? One of them turned up to the first Twincam Bathurst cruise I went on, guy who drove it was in a wheelchair.

I have seen a company that does hand controls for the accelerator like the one in the video so that is cool, but might just have to settle for a levered brake, think that would be a decent combo.

He has full use of his hands just no use of his legs, not an amputee though.

Hiro, yes..

why cant you adapt allready proven electronic controls that are factory fitted on a lot of cars?

the electronic throttle for example on later model camrys etc...

and the same for the brake pedal.

i would start with a car that has an electronic brake for a start (as that would be the hardest to modify if the car doesnt allready have it) and just run another switch that can be operated by hand.

install a complete engine that has an electronic throttle and do the same thing; the standard pedals could remain 'in parallel' for use by non-disabled drivers (if the pedals get in the way of the paralyised legs then they could have a quick release type system)

i am still assuming that this will be a car primarily for racing only, and therefore unrestricted by on-the-road legalities. ripfast is this the case?

I think this is the million $ question ^^^^^

If you need it road legal, then the electronic remote brake control just isn't going to cut it. What happens if the battery goes flat (or something)?

You also have to remember that the throttle needs to worked independant of the steering wheel angle, plus with the forces of the turning car acting on the body.

Ithink the best system I saw was a push level for the brake with a twist grip (like a motorcycle) for the throttle on the end of it.
Therefore, one hand for the throttle/brake (generally right hand), and left hand on the steering wheel with a turn knob.
this system works best with Euro cars as the left hand (turning) can then also work the indicators, though again, a motorcycle turn switch could be put onto the brake/throttle lever.

BTW, it's only F1 cars & the road legal Italian type supercars that use flappy paddles for gearshift. If you look at a WRC car, the gear change is a full ring behind the wheel (pull/push) so that it can be operated no matter the steering wheel angle. Not quite the same, but similar principal.

I'd certainly be avoiding doing something completely ghetto for road use, when you're toying with the blokes safety i think KISS would apply here, while electronic shit would be great, the tried and tested (and engineered..) option is probably the wisest (albeit most expensive) option..

**ripfast** · 06-11-2009, 10:51 PM

yeah i know the tried and tested is really the only way to go to be road legal, but thought someone might have come up with a certified electronic version by now.

**o_man_ra23** · 14-11-2009, 08:20 AM

I could probably design and develop an electronic system and get it certified for you, but I really don't think you would appreciate the cost. Then again, you might be related to Bill Gates...

There already is a car on the market with an electronic handbrake. It operates like a truck spring brake that is, spring on & power to release or hold off. If the power fails the brake automatically comes on.

**andrew_mx83** · 14-11-2009, 02:46 PM

that could be nasty.... short the elecrical system halfway thru a corner and handbrake comes on?

**ripfast** · 23-11-2009, 08:53 PM

yeah i think he will have to settle for levers, i just cant believe that no one does electronic conversions with paddles behind the wheel, thought it was a logical step with fly by wire systems.
