Compute the fraction of available torque to be delivered to each wheel and gather a list of all wheels connected to the differential.

Additionally, add wheel constraints for wheel pairs whose rotational speed ratio exceeds the corresponding differential bias.

Parameters:

• axleDescription – [in] is a decription of the axles of the vehicle and the wheels on each axle.

• diffParams – [in] describe the division of available drive torque and the biases of the limited slip differential.

• wheelStates – [in] describes the rotational speeds of each wheel.

• dt – [in] is the simulation time that has passes since the last call to PxVehicleDifferentialStateUpdate()

• diffState – [out] contains the fraction of available drive torque to be delivered to each wheel.

• wheelConstraintGroupState – [out] describes the groups of wheels that have exceeded their corresponding differential biases.
