- // Slip curves do not represent the coefficient of grip. Instead they represent
- // the reaction to the current slip. Regardless of the peak value in this curve,
- // it will be automatically normalized to have a peak of 1.0.
-
- // The peak of the slip curve is dynamically adjusted to higher or lower slip
- // values based on current load and possibly other factors. See the LatPeak and
- // LongPeak tire parameters for more info.
-
- // Slip curve data points are connected using a cubic spline, so there is no
- // need to use a massive amount of data points unless the curve is really busy.
-
- // Lateral slip angles are normalized so that 90 degrees is 1.0. Longitudinal
- // slip ratios closely match the SAE definition.
-
- // All curves should probably go out to at least a slip of 2.0, even the lateral
- // and braking curves. Although locking up your brakes is a slip of 1.0, there
- // are situations where you can spin your wheels in the opposite direction of
- // your velocity (like shifting into reverse while moving forwards).
-
- // Note that the initial slope of the curve may have an effect on how some
- // features behave, such as traction control, skids, and tire smoke.
