void PxVehicleTireGripUpdate(const PxVehicleTireForceParams &tireForceParams, const PxVehicleRoadGeometryState &roadGeometryState, const PxVehicleSuspensionState &suspensionState, const PxVehicleSuspensionForce &suspensionForce, const PxVehicleTireSlipState &tireSlipState, PxVehicleTireGripState &tireGripState)

Compute the load and friction experienced by the tire.


If the suspension cannot place the wheel on the ground the tire load and friction will be 0.0.

  • tireForceParams[in] describes the tire’s friction response to longitudinal lip angle and its load response.

  • roadGeometryState[in] describes the plane of the road geometry under the wheel.

  • suspensionState[in] is the current suspension compression state.

  • suspensionForce[in] is the force that the suspension exerts on the sprung mass of the suspension.

  • tireSlipState[in] is the tire longitudinal and lateral slip angles.

  • tireGripState[out] is the computed load and friction experienced by the tire.
