Note

If constraintGroupState is set to NULL it is assumed that there are no requirements for any wheels to have the same angular or linear velocity.

Parameters

axleDescription – [out] identifies the wheels on each axle.
wheelParams – [out] specifies the radius of each wheel.
engineParams – [out] specifies the engine’s torque curve, idle revs and max revs.
clutchParams – [out] specifies the maximum strength of the clutch.
gearboxParams – [out] specifies the gear ratio of each gear.
brakeResponseStates – [out] stores the instantaneous brake brake torque to apply to each wheel.
actuationStates – [out] stores whether a brake and/or drive torque are to be applied to each wheel.
tireForces – [out] stores the lateral and longitudinal tire force that has developed on each tire.
throttleResponseState – [out] stores the response of the throttle to the input throttle command.
clutchResponseState – [out] stores the instantaneous clutch strength that arises from the input clutch command.
differentialState – [out] stores the instantaneous torque split between the wheels.
constraintGroupState – [out] stores the groups of wheels that are subject to constraints that require them to have the same angular or linear velocity.
wheelRigidBody1dStates – [out] stores the per wheel angular speed to be computed by the component.
engineState – [out] stores the engine rotation speed to be computed by the component.
gearboxState – [out] stores the state of the gearbox to be computed by the component.
clutchState – [out] stores the clutch slip to be computed by the component.
