Detailed Description

Tire load variation can be strongly dependent on the time-step so it is a good idea to filter it to give less jerky handling behavior.

Note:

The x-axis of the graph is normalized tire load, while the y-axis is the filtered normalized tire load.

The normalized load is the force acting downwards on the tire divided by the force experienced by the tire when the car is at rest on the ground.

The rest load is approximately the product of the value of gravitational acceleration and PxVehicleSuspensionData::mSprungMass.

The minimum possible normalized load is zero.

There are two points on the graph: (mMinNormalisedLoad, mMinNormalisedFilteredLoad) and (mMaxNormalisedLoad, mMaxFilteredNormalisedLoad).

Normalized loads less than mMinNormalisedLoad have filtered normalized load = mMinNormalisedFilteredLoad.

Normalized loads greater than mMaxNormalisedLoad have filtered normalized load = mMaxFilteredNormalisedLoad.

Normalized loads in-between are linearly interpolated between mMinNormalisedFilteredLoad and mMaxFilteredNormalisedLoad.

The tire load applied as input to the tire force computation is the filtered normalized load multiplied by the rest load.
