F1 2012 Brake BIAS

[Befaro]

Hello ,
thanks for taking your time to view this thread.
I have a short question: Does anyone know how much the Brake-Balance gets adjusted when you switch to "REAR" "NORMAL" and "FRONT"? Is there a numeric value involved? Like +/- 5%?
regards
Robin

I don't think anyone knows, I have not seen a definite number ....... just people guessing

1% sounds low ..... 5% maybe a good guess, but sounds a bit high to me

E.g. in the ca2_bahrain.ctf file there are following values:

• break_bias_forward: 0.616923
• brake_bias: 0.576923
• break_bias_backward: 0.516923

This has led me to believe, that the difference is 5% as mentioned by Graham. I haven't tested what happens if I change the values though.
On separate note when comparing to last years' values, they were 0.5, 0.6 and 0.7.
in the same file the brake_torque values are 2600 for f12012, compared to 3200 for F12011. I think that is one of the reasons, why the breaking distances are longer in this year's game (the brakes are weaker).

That's a difference of +4% for front and -6% for back working from the neutral position.

What are the differences on other tracks, cause maybe it's track-dependant?

Staying with Caterham, for Monaco & Monza, in Monaco the brake_bias is bit smaller (0.574468 vs. 0.576923) and the brake_torque_forward is 2350 vs. Monza's 2600. And quick look at Hockenheim, Korea & Sepang reveals, they are the same as for Monza. And these values seems to be the same for McLaren too in other tracks except Monaco.

Just looked at the data in states.bin. For the car setup screen, the values are

• balance_min="0"
• balance_max="-5"
• balance_range="20.0f"
• range_begin="40"

The last two are clear, i.e. the beginning of the range and the total range (i.e. 40%-60%). What I don't really know/understand, is what the balance min means, i.e. does it mean, that the 40% setting is actually the break_bias mentioned above, i.e. then 50% value would already be -2.5 towards back, i.e. the roughly .6. Any ideas?
