  • Car driven by a joystick.

    tonight i was at work and i was watching family guy when one of our tuesday night regulars came in. i was talking to my boss and showing him the mp3car site because he had expressed an intrest in what i was doing and thought it was kool. and the regular overheard us an said that he was in the process of building his carpc. so i checked it out, and it wasnt to bad. and he was joking around and said "now all i need to do is lose the steering wheel and put in one flight control sticks you can buy at a used airplane parts store and it will all be done!" lol. I got to thinking and looked up a local airplane parts supplier and gave them a call. they had on in stock that needed to be repaired. but it was for sale. im not going to start a project out of it, but i thought it would be cool thinking about it......when you want to speed up, you push the flight stick forward and the cars cruise control servo opens her up. lol. it would suck if the system had failed and you were doing 80+. has any else thought about this?

    Well it has been done on concept cars bit it would be a bit wierd for those of us used to driving with conventional controls.

    YOu don't need a carPC to do it. A lot of cars now are drive-by wire so you can just use any method of controling the systems you want.

    While cars still have a mechanical linkage between the steering wheel it is easy to do away with it on these modern cars with electric power steering. I have seen something like this done on speed sensitive steering that actually changes the angle the wheels turn in relation to the wheel in response to speed. A step further from those cars that weight up the steering at speed.

    But a few cars now have fully electronic throttle control as it makes things like cruise control easier to do and you dont have to worry about cables snapping. Most cars from the mid 90's on have stepper motors to control the idle so its not really anything new.

      they did this on scrap heap challenge (junk yard wars) or whatever it's called on differnt continents... you know the one... do a challenge with a bunch of **** frm a (carefully loaded) junk yark.

      Anyway, they used cars with auto throttle and power steering to make full size radio control cars. It was quite funny as i recall. that's pretty "fly by wire"!!! in fact, add a web cam and you could drive your car to work and still telecommute from bed.

        Well aircraft have been able to takeoff, fly and land without the pilot having to do anyhting for many years. Cars are a little bit more tricky as people get in the way.

          There must be a reason why there are pilots in there.

              The throttle in my 01 Firebird is fully electric, and I don't like it because the only way to adjust the idle is to reprogram the car's ECU. I tried to trick it by rigging the peddle to stay slightly pressed, but when I start my car the ECU adjust the engine's RPM back down to the programmed amount.

                my car has a mechanical cable and the only way to adjust the idle is at the ECU also as it has a stepper motor to control idle to allow it to adjust for electrical, AC and PAS loads.

                If you have idle problems try re-learning your ECU by resetting it and then when you run it again to allow it to re-learn turn all the electrical devices and AC on. That is what we do on Pugs that are mis-behaving at idle. But obviously you shoudl look into it better for your car.

                  The problem with removing the mechanical link with the steering wheel is that you'll lose all control if your system fails. With power steering you can still drive with the power steering broken.

                  Besides, I don't think ANY production cars have drive by wire steering. I've only seen DBW for the gas pedal. Breaks and steering need to work without the engine running and without electrical power.

                    well it's not really a problem, it's doing what it's built to do. I have a high output alternator that doesn't turn on untill 900 RPM. The stock alt would turn on around 600, so that's where my engine's RPM stays at nuetral. Problem is whenever I'm stopped, or anytime my RPM drop below 900, my voltage will go from about 15-16 to less than 10, causing problems like my computer will restart.

                    Another solution I'm thinking about trying is getting a smaller pully for the alternator. Think that might work?

                      yeah of course a smaller pulley would work. effectively gearing it up.

                            Let me reword, I knew it would work, but thought there might be a reason they keep the alt. from kicking on below 900 RPM.

                              no idea. i didnt know they stopped it kicking in.

                              possibly because the engine might not have enough torque at less than 900rpm to support the load (Lens' law)
