Electronic Brake Assist

Wheelie control has been around for a while. Why can't a manufacturer create stoppie control?

All you need is an electro hydraulic brake assist. Plus, I have two reasons to suspect it's on the way.

1) HRC's golden boy can't brake for his life. Honda must be working on some stuff to help him use the front tire as much as possible. TC is what helped him learn how to turn a big bike
<
why wouldn't Honda go one step farther?

2) Gibby's somersault at Catalunya is something no one likes to see. Unlike TC, whose safety gains were exaggerated, stoppie control could actually eliminate quite a few gruesome accidents.

I think its safe to say they don't already have it, or at least Ducati doesn't because it wasn't around in 2006, but how much longer?

If it is developed will it actually cause further harm GP? If everyone can hamfist it equally what's the point in having late braking skills? Doesn't stoppie control mean the advantage would actually go to the taller, heavier riders who can hang off of the back? Isn't that status quo or would the big riders get exponential help from such a system?

What about ABS? Do you think they will start using it for wet races

Well really given that its a moto development formula, I guess I would have to say it is a development so I would handle acceptance of ABS etc. Even though Gibbers may not have had it I kinda think they'd already have that sort of stuff anyway, especially on the back to prevent high sides .... maybe a close up picture of the brake master cylinders would show it?? Couple of wires into a pressure relieving type mechanism ..... bit of software to read lockup .... yeah In a way I'd be surprised if its not already in there.

Mind you whilst perusing the Motegi race stuff, and mulling all this "my rider is better than yours, and this bike is better than that" .... I was thinking gee I wonder if Honda could ever get Asimo ( the real one LOL ) to ride a moto .... in which case we could use it to judge which bike is better than that.

It all sounds pretty far fetched but hey I'm not really that sure its that impossible in the near future.

hahaha talk about boring!!! .... I think I watch it for the riders I realise...
 
Stoppie control really won't help Pedrosa or any other rider for that matter. The issue is not about brake modulation, but when to START braking.

Obviously, all riders want to brake as late as possible -- this is a judgement call. Lets assume that they do have "stoppie control" If they brake too late, they will still over shoot the turn/run wide. If they brake too early, their competitors will pass them.

you got it - now how about a one tire make policy and taking out traction control - back to rider+bike loke with the 500 2-strokes, slides and drifts again
 
i think Pedrosas problem with braking is his lack of upper body strength more than anything. he can brake as hard as anyone - just not lap after lap afer lap.

i don't think abs will help him any
 
I don't think it has much to do with upper body strength as he did ok on those 250cc bikes (whther its 250cc or 990, his arms hold up only his body weight) but, it might some thing with him not having enough weight (isn't he the smallest rider out there?) over the rear wheel causing it to lift earlier than those of other riders..
 
yes but keeping the back wheel in-line with the front when it's lifting under braking takes a lot of strength - that dani doesn't have.
 
Well Lexi, its a good question. I'm not so sure it would help though because as Crv said, its a matter of when the brake is applied comming into the turn.

I agreed to a certain extent. The real question becomes, what is more important, the show of racing or the development of human endeavor in regards to racing technology? Engineers will continue to develop technologies that make a vehicle go around a track faster and faster to compensate for human flaw and maximize the laws of physicals toward performance. But this increased technology can (and some would say it already has) made the racing more boring.

Certainly ABS is a technological advancement, but remember, it is banned in F1 (the pinnacle of racing technology). Why? Well simply, because it takes something out of the driver's ability to control the vehicle under braking and makes it more an exercise of pure engineering, assuming the drive brakes in time.

So yes, even though ABS is a technological advancement, it is still, in fact banned. Speaking of technology, I wish traction control was banned too because, even though the technological advancement is intriguing, it takes a large degree of the human element out of the equation.

Yes, this is my point exactly. Modulation is more important than anything because when the rear wheel comes off the ground the amount of strength/bravery it takes to get it back on the ground so you can trail brake into the turn is something I can't even fathom at the GP level.

Pedrosa doesn't brake early b/c he's too dim to find the right braking marker, he brakes early because he doesn't have the strength or the weight (why the hell doesn't he just put on 5-10kg. of muscle?) to keep the rear wheel under control. He's also not much of a wind sail.

Electronic Brake Control would allow Pedrosa to hamfist it and never miss his turn in point b/c the bike would never let the back off the ground.

Plus, anytime the rear wheel is off the ground you are wasting time. One of your contact patches is not on the pavement, and the bike has a higher more forward cg which makes it wanna fli. You have to back off or hang off the back even more than if you never lifted the wheel.
 
I cannot see how it could work except on a playstation. Getting into a turn quickly and how the front tyre reacts with the fork and rider input is a much more complicated task than gassing off the exit and takes far more skill. An even more important factor in braking is where to get off the brake, just as important as a braking point. Crvlvr said it's a judgement call, spot on. Guys may change little things they do all through a race dependant on what they are planning to do. The difference in presure on the front lever between a rear wheel 1 inch or 3 inches off the deck is miniscule but any rider can feel that, so even if it did could work ther's no way I could see any of these guys actually wanting it.

ABS in a wet race, carbon fibre discs are swapped for traditional steel items in the rain so the braking force on the front end is already much less, it has to be. It would have to be pretty advanced to be smooth so I suppose it could work. I don't believe it could really make a huge difference to someone like Ant West so I'd be dead against it.


But I gotta call this one...to say that Dani can't brake is really a bold/ludicrous statement, bullsit actually. Carbon fibre discs allow most of these guys to brake with one or two fingers so all this 'Dani can't brake' stuff leaves me laughing, I don't know how strong he is, but if he can race a GP bike for 45mins, he ain't no ...... How is he 3rd in the champoinship then?
 
The limiting factor with the breaking on a gp bike is the rider being able to hold the back wheel down, brake assist wont help that
 
As far as i know, braking in MotoGP is all about the rider's weight distribution on the bike. So I can't imagine that some kind of electronic brake assistant or whatever will ever be a great help. At least I hope so. The less electronical aids on the bikes the better for us.

That is probably also the reason why Pedrosa is always so bad on the brakes. He just doesn't have the weight and, due to his short arms and legs, the ability to distribute it as well as other riders do. Ever wondered why tall, lanky riders with long arms and legs like Rossi or Dovizioso were able to brake so late?

Exactly, he's obviously doing something right. And that young fella that happens to have won the championship this year is not the biggest bloke on the bike either. Now the question is, will putting on more muscle make Dani that much better. I'd be happy just to see him smile more, yuck it up a bit after a good performance, and just look like he is enjoying the sport.
 
It doesn't have that much influence on skill but some riders got problems pulling celebratory wheelies
