TC and ABS - how does rF use it?

LesiU

How exactly rF use that parameters? Is it about just bumping tyre grip or something more complex is going on?

For example, TC lines:
TractionControlGrip=(1.0, 0.2) // Average driven wheel grip multiplied by 1st number, then added to 2nd
TractionControlLevel=(0.3, 0.5) // Effect of grip on throttle for low TC and high TC


ABS lines:
ABSGrip=(1.0, 0.2) // Grip multiplied by 1st number and added to 2nd
ABSLevel=(0.2, 0.4) // Effect of grip on brakes for low ABS and high ABS
 
It's not just about bumping grip up. There's some sort of abs ad TC logic going on.

In our league mod we actually have reduced grip levels for abs and TC. For TC anytime the gas is being applied grip of the driven tires is reduced, and speed at the end of a straight is greatly reduced. Same thing for abs, when braking the non abs car can brake deeper but has a greater chance of locking the wheels at some point.
 
Maybe that's because of aid penalties (additional weight) defined in hdv file?
 
It's the grip. Our lines read as followed

TractionControlGrip=(0.97, 0.0)
ABSGrip=(0.97, 0.0)

Both aids have a ballast penalty of 5kg, but I can turn abs on and off with no effect on the top speed. Turning the TC on and off can effect top speed by 10mph or more. This is how I know that grip is reduced to the driven wheel given our parameters. You can feel the same effect with how deep you can brake with abs off, even with a higher fuel load then with it on. In the examples you have abs and TC would actually give the tires more grip.

Also moving from qual fuel of ~15l to race load of ~120l on the same tires only reduces the top speed by <5mph. That's with a difference of about 80kg.

Thanks, so that means, these values should provide no gain or loss of tyre grip, when these aids are on:
TractionControlGrip=(1.0, 0.0)
ABSGrip=(1.0, 0.0)

What about:
- TractionControlLevel // Effect of grip on throttle
- ABSLevel // Effect of grip on brakes

What kind of "effect" is that, between tyre grip and throttle/brakes?

Let's say, we have TractionControlLevel=(0.3, 0.5). Is that means, filtered throttle will be limited to 30 and 50% for low and high TC respectively?
How tyre grip affects that (because it is - that's what description says)?

Hmm, those might be the biggie variables instead of the .97 of the other 2 parameters. Someone would have to test it out.
 
I'm quite sure tire grip isn't adjusted with the TC / ABS parameters, but its somewhat misleading. I think these grip factors adjust how harsh the TC / ABS do their job based on something like the 'currently used grip %'. Values greater than 1 don't increase tire grip but make the TC / ABS start 'later', possibly to the point where you can lock all tires with certain ABS settings.. Haven't spent a lot of time but just wanting to say it never changed my tire grip.
 
I've never worked with TC, only some ABS. Tire grip changes wouldn't really change top speed though, as in no car you're near the grip limit just going straight?

Perhaps the TC parameters are set too sensitive so it sees even the very small wheelslip you have as 'too much' and applies a tiny bit of TC even in top gear?

Typically you see the first value at least 1 and the second above 0, perhaps if something like the total is less than 1, you might get these things, but as said I haven't used TC ever so I may be talking from my behind.
