Esotic Slips Hud V1.2

shows tire slip under braking and slip angle under cornering

  1. Esotic
    Demo Video:

    As a big caveat, this app is hard coded to work best with Formula and GT cars (or anything using racing slicks). Some of the work to be done is to somehow graph all the tire compounds in AC and discover the real slip angle curves (slip angle vs lateral force or coefficient of friction).

    In terms of the logic I have hard coded values for min_slip (3) and max_slip (10). I have assumed that "optimum slip" is right in the middle of these two values. The colors in the video are as such:

    While Braking (brake input > 20%) it shows Tire Slip:
    color starts as black and become brighter purple as you approach the braking threshold. If you lock up (or get dangerously close to locking up) it turns red.

    While Cornering:
    slip < min_slip starts as black and becomes whiter the closer the value gets to min_slip
    min_slip < slip < optimum_slip starts as medium green and becomes bright green
    optimum slip < slip < max_slip starts as bright blue and fades to medium blue
    max_slip < slip is bright red

    "Graphically" this would look like

    0 ------------- 3 | 3 --------------------------- 6.5 | 6.5 --------------------- 10 | 10 +
    black to white | med green to bright green | bright blue to med blue | bright red

    A tire has maximum grip at the optimum slip angle, which I am assuming is 6.5 for racing tires. If you keep the tires in the bright green while cornering, then you should be getting near maximum grip in the corners while also giving yourself a little lee-way if the slip angle increases.

    Any feedback is appreciated, especially suggestions for how to make it better. :)

    Thanks a lot. Is it possible to change the size of this hud, like by using an ini?

    A really nice to have real time slip data. Thank you. Could you make the app scalable in size? I am a nvidia DSR user..

      This sounds like a reasonable request. I have added it to my ToDo list.

    Could be really useful, however tyre model 10 is causing me issues with this app, as braking display is not working and I had to go into python (using notepad ++) to change the size of the app, especially gap between wheels as they were 600 and 200 which just took up to much on single display 1080p, also it would be useful to have tyres disappear when not registering above a threshold value.

    Keep up the effort though this has a lot of potential to be really helpful and thank you.

    thank you, very useful & effective ....
    the cockpit of the real Corvette Gt3 has something similar to display traction loss/tyre skid under braking..... is it possible to implement a smaller display or a kind of floating cockpit instrument (similar to sidekick, for example...) ?
