Calculated Brake Pressure
Posted: Sat Jun 17, 2017 12:23 am
Is it possible to create a calculated brake channel based on negative g acceleration in the forward direction?
I'm open to doing this post run via excel. Or alternatively via a calculated math channel in LUA.
I'm clueless as how I might correlate negative G to brake pressure.
Has anyone tried this?

Here is a way that it has been done.
I wrote a script that included it which is in the second post here:

I found some time tonight to integrate your brakeg script. I ran into two issues; see bold. The first was the missing parentheses. Easy enough. The second was that brakeG was displaying acceleration Gs. I removed the sign switch and that fixed the issue.
Code: Select all
if b2>0 then
Now that I have brakeG I assume I point RaceRender at this channel as my brake input. How did you scale it from 0 to 100 for brake input? Can you set 0 Gs = 0 and my highest brake G as 100? This doesn't necessarily represent the brake pedal input. Am I missing something or is this as good as it gets without a brake pressure sender?

Yes, I did miss a parenthesis.
I haven't really played with this too much but your suggestion of scaling the result from 1-100 seems reasonable.

boggie what did you decide to do about scaling the data?

This worked great. Really good document to explain everything as well. Thank you.
I scaled it 0-100 and ended up needing to use 200000 instead of the 50000 called out in the PDF. Our 318ti chump car is a bit less aerodynamic than a Formula Ford used in the documentation haha.
