Throttle Pedal Feedback

[marcush.]

you´d efinetly need some sort of alarm or feedback modulation to even think it could be useful..you need to compensate for reaction time -it would work like anticipated reaction but in a sense of feed forward activity warning you of grip levels on the brink of reaching maximum performance..?
It´s not like you have a steady state situation and can adjust the throttle as needed ..it´s a quickly changing scenario where you either anticipate ,just floor it .progreesively feed in throttle .....the guidance of the system would need to account for the change quite quickly,no?

yes like shift lights are a few tenth b4 the optimum shift points, it will have to be a modulation as well
it is not like traction control where the pedal doesnt match the throttle so i think it is still legal within the rules today

I still don't see how this would be practical or useful. Or what advantage it has over the conventional system.

If all it's doing is giving you feedback - the driver already has more than enough to know when he's at or over the limit. In fact, the driver will know MUCH better than an onboard computer will. A data system has no idea what the state of the tires are, where the grip margin is, where the "optimal" slip angles and ratios are. They'll be all over the damn place, particularly with inconsistent tires. Admittedly you could have a steering wheel control for how much "slip" you allow, but MOST importantly...

...given that the driver's right foot is what they're using to control the throttle I don't want to be having to chase the thing being stiffer or softer or whatever. I want it predictable so it's easy to modulate.

Remember the driver already has feedback about the rear of the car coming from the vehicle sideslip angle and the yawrate (which includes the sideslip velocity). Also the longitudinal acceleration tells helps the driver understand the limit of the tyres in traction.

useles for a driver who knows the plot .
You don´t need to learn how to drive to the limit ..I think you cannot even learn it .You feel it or don´t .The ones who can decipher good from over the limit are the real masters ...the others trash their tyres.

I agree with the previous points that the driver already has the mechanical feedback to know what is going on, being bolted down in the car will allow him to feel everything the chasis is doing, in a road car, and evern more so on a road sports bike, you can feel the rear letting go or reaching its limit, the combination of engine vibration, the sound of it revving (easier or harder than normal) and the suspension unloading and squating gives you everything you need to know that the rear wheel is slipping even when on slow mo camera it looks fine.

A good suspension setup and a focused driver will know what is going on. I would take a guess and say the bodies natural gyroscope (the inner ear) paired with peripheral and accute vision are the bodies tools to tell you when things are changing where you cannot see them.

Actually, i wonder what would happen to an f1 drivers driving senses if he were suffering from vertigo, i would guess he would barely be able to feel the feedback through the car and make sense of it.

But yeah, i dont think artificial feedback is needed anywhere in real life, its good in video games though!

the 'natural gyroscope' (an accelerometer array) is ALWAYS searching for visual and tactile referencing to update itself
(hence motion sickness and simulator sickness, due to conflicting cues)

even a good reference is only held for 5-6 seconds anyway
(we don't notice this as we are normally updating with non-conflicting (re)referencing)

(any flight school can provide a real-life demonstration of this, the best £100/$100 you could ever spend !)
with visual reference removed anyone can turn and recover a plane by feel if the turn lasts only 5 sec, beyond this everyone's sense of balance is confused by starting to rereference itself to regard the turn as normal ie level

impaired/misleading visual references due to whiteout or incipient ground mist will give problems even on a motorbike

likewise with good visual references if you have a bit of vertigo (which is caused by over-damping of the accelerometers)

........ this all from experience

Interestingly in an electric race vehicle the driver can 'hear' the tyres which gives much better feed back to the driver.
With a flat torque curve from the electric motor this allows the driver to get even closer to the cornering limit and also gives the driver better control over tyre wear.
Potentialy electric F1 would be much faster than ic.
