PxReal PxVehicleEngineData::mDampingRateFullThrottle

Damping rate of engine when full throttle is applied.

Note

If the clutch is engaged (any gear except neutral) then the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchEngaged and mDampingRateFullThrottle: mDampingRateZeroThrottleClutchEngaged + (mDampingRateFullThrottle-mDampingRateZeroThrottleClutchEngaged)*acceleratorPedal;

If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchDisengaged and mDampingRateFullThrottle: mDampingRateZeroThrottleClutchDisengaged + (mDampingRateFullThrottle-mDampingRateZeroThrottleClutchDisengaged)*acceleratorPedal;

Specified in kilograms metres-squared per second (kg m^2 s^-1).

Range: [0, PX_MAX_F32)

PxReal PxVehicleEngineData::mDampingRateZeroThrottleClutchDisengaged

Damping rate of engine when full throttle is applied.

Note

If the clutch is engaged (any gear except neutral) then the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchEngaged and mDampingRateFullThrottle: mDampingRateZeroThrottleClutchEngaged + (mDampingRateFullThrottle-mDampingRateZeroThrottleClutchEngaged)*acceleratorPedal;

If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchDisengaged and mDampingRateFullThrottle: mDampingRateZeroThrottleClutchDisengaged + (mDampingRateFullThrottle-mDampingRateZeroThrottleClutchDisengaged)*acceleratorPedal;

Specified in kilograms metres-squared per second (kg m^2 s^-1).

Range: [0, PX_MAX_F32)

PxReal PxVehicleEngineData::mDampingRateZeroThrottleClutchEngaged

Damping rate of engine when full throttle is applied.

Note

If the clutch is engaged (any gear except neutral) then the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchEngaged and mDampingRateFullThrottle: mDampingRateZeroThrottleClutchEngaged + (mDampingRateFullThrottle-mDampingRateZeroThrottleClutchEngaged)*acceleratorPedal;

If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchDisengaged and mDampingRateFullThrottle: mDampingRateZeroThrottleClutchDisengaged + (mDampingRateFullThrottle-mDampingRateZeroThrottleClutchDisengaged)*acceleratorPedal;

Specified in kilograms metres-squared per second (kg m^2 s^-1).

Range: [0, PX_MAX_F32)

PxReal PxVehicleEngineData::mMaxOmega

Maximum rotation speed of the engine.

Note

Specified in radians per second (s^-1).

Range: [0, PX_MAX_F32)

PxReal PxVehicleEngineData::mMOI

Moment of inertia of the engine around the axis of rotation.

Note

Specified in kilograms metres-squared (kg m^2)

PxReal PxVehicleEngineData::mPeakTorque

Maximum torque available to apply to the engine when the accelerator pedal is at maximum.

Note

The torque available is the value of the accelerator pedal (in range [0, 1]) multiplied by the normalized torque as computed from mTorqueCurve multiplied by mPeakTorque.

Specified in kilograms metres-squared per second-squared (kg m^2 s^-2).

Range: [0, PX_MAX_F32)

PxReal PxVehicleEngineData::mRecipMaxOmega

private

Reciprocal of the maximum rotation speed of the engine.

Note

Not necessary to set this value because it is set by PxVehicleDriveSimData::setEngineData

Range: [0, PX_MAX_F32)

PxReal PxVehicleEngineData::mRecipMOI

private

Reciprocal of the engine moment of inertia.

Note

Not necessary to set this value because it is set by PxVehicleDriveSimData::setEngineData

Range: [0, PX_MAX_F32)

PxFixedSizeLookupTable<eMAX_NB_ENGINE_TORQUE_CURVE_ENTRIES> PxVehicleEngineData::mTorqueCurve

Graph of normalized torque (torque/mPeakTorque) against normalized engine speed ( engineRotationSpeed / mMaxOmega ).

Note

The normalized engine speed is the x-axis of the graph, while the normalized torque is the y-axis of the graph.
