i was just going through this article regarding 2014 F1 rules and this jumped out as the most interesting aspect ....

Harvesting this much energy under braking will affect the braking effect at the rear wheels, so an electronic rear brake control system will be allowed.

This will be used to offset the ERS-K effect by aiding the braking effort at the rear, negating the need for the driver to constantly alter the brake bias.

this reminded me of the mclaren's third break pedal in 1998 MP4-13 used by DC as a mean of aiding corner entry.

http://www.f1fanatic...ar-brake-pedal/

The pedal allowed the drivers to operate either of the rear brakes independently of the others. This gave them two additional means of controlling the car and improving the performance – by reducing either understeer or wheelspin depending on which wheel was braked and when.

with the aid of electronic control of the break bias, who is to say the system won't be used as a form of 'Traction Control' by the clever boffins of F1???

any thoughts on that??? any more information??? share please.

Well, if they do use it as Traction Control, then everybody will have it, cos' the brake stuff will be integrated in the FIA ECU made by McLaren - and that's the same for every car and cannot be manipulated without being detected. So what's the big deal?

remember torque map??? it was controlled by the same standard ECU but only used by the Renault powered teams as way to control wheel spin ... and subsequently clamped down by FIA.

IIRC, the software and the maps are done by the teams themselves, MES just supplies the hardware and firmware.

It will at least be used as ABS and remove one of the trickiest parts of modern F1 - late braking without locking up the rears. Ask Massa.

nah, i don't think it'll be as obvious as that, using as ABS directly will be noticed , it'll have to be much subtler than that. maybe certain aspects of ABS , then again, it's the front that gets locked easily.

Won't this system only operate when, er, the brakes are on?

Aren't rear lock-ups quite rare?

The brakepads and disks will be toasted if used as traction control.

No, or yes, you always try to maximize rear brakes but you have to leave a safety margin so you wont do a Massa. If you add electronics, you can easily use that to release the energy recovery if the rear comes to a stand still, wich will, of course, set the wheel in motion again.

[wingwalker]

Oh crap, that does indeed sound like the TC trick which allowed teams to have what effectively was rear-axle ABS. If there's really no other way I say ditch the KERS altogether.

nop, mclaren used it in whole of 1997 and 1998, i presume with better material and cooling and clever electronics, it won't be a problem.

[Ross Stonefeld]

They had an extra pedal and a system that was banned.

[GlenP]

I can't see how you could exploit it for brake-steer, since you would either have to have it so that the car "knew" which way it was turning (not legal), or there was an additional pedal (also not legal as far as I know), or some sort of steering/braking link (again…).

It will amount to a form of ABS, sure.
