PxReal PxVehicleEngineData::mDampingRateFullThrottle

Damping rate of engine in s^-1 when full throttle is applied. Damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchEngaged and mDampingRateFullThrottle if the clutch is engaged. If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchDisengaged and mDampingRateFullThrottle. Range: (0,inf)
.

PxReal PxVehicleEngineData::mDampingRateZeroThrottleClutchDisengaged

Damping rate of engine in s^-1 at zero throttle when the clutch is disengaged (in neutral gear). Damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchEngaged and mDampingRateFullThrottle if the clutch is engaged. If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchDisengaged and mDampingRateFullThrottle. Range: (0,inf)
.

PxReal PxVehicleEngineData::mDampingRateZeroThrottleClutchEngaged

Damping rate of engine in s^-1 at zero throttle when the clutch is engaged. Damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchEngaged and mDampingRateFullThrottle if the clutch is engaged. If the clutch is disengaged (in neutral gear) the damping rate applied at run-time is an interpolation between mDampingRateZeroThrottleClutchDisengaged and mDampingRateFullThrottle. Range: (0,inf)
.

PxReal PxVehicleEngineData::mMaxOmega

Maximum rotation speed of the engine, specified in radians per second. Range: (0,inf)
.

PxReal PxVehicleEngineData::mPad[2] [private]

PxReal PxVehicleEngineData::mPeakTorque

Maximum torque available to apply to the engine, specified in Nm.

Please note that to optimise the implementation the engine has a hard-coded inertia of 1kgm^2. As a consequence the magnitude of the engine's angular acceleration is exactly equal to the magnitude of the torque driving the engine. To simulate engines with different inertias (!=1kgm^2) adjust either the entries of mTorqueCurve or mPeakTorque accordingly. Range: (0,inf)

PxReal PxVehicleEngineData::mRecipMaxOmega [private]

Reciprocal of the maximum rotation speed of the engine. Not necessary to set this value because it is set by PxVehicleDriveSimData::setEngineData Range: (0,inf)
.

PxFixedSizeLookupTable<eMAX_NUM_ENGINE_TORQUE_CURVE_ENTRIES> PxVehicleEngineData::mTorqueCurve
