Member Data Documentation

centerBias

PxReal physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::centerBias

Maximum allowed ratio of average front wheel rotation speed and rear wheel rotation speeds. The differential will divert more torque to the slower wheels when the bias is exceeded.

Note

Only applied to DIFF_TYPE_LS_4WD

Range: [1, inf)

frontBias

PxReal physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::frontBias

Maximum allowed ratio of front-left and front-right wheel rotation speeds. The differential will divert more torque to the slower wheel when the bias is exceeded.

Note

Only applied to DIFF_TYPE_LS_4WD and DIFF_TYPE_LS_FRONTWD

Range: [1, inf)

frontNegPosSplit

PxReal physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::frontNegPosSplit

Ratio of torque split between front-negative and front-positive wheels (>0.5 means more to frontWheelIds[0], <0.5 means more to frontWheelIds[1]).

Note

Only applied to DIFF_TYPE_LS_4WD and DIFF_TYPE_LS_FRONTWD

Range: [0, 1]

frontRearSplit

PxReal physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::frontRearSplit

Ratio of torque split between front and rear wheels (>0.5 means more front, <0.5 means more to rear).

Note

Only applied to DIFF_TYPE_LS_4WD

Range: [0, 1]

frontWheelIds

PxU32 physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::frontWheelIds[2]

The two front wheels are specified by the array frontWheelIds.

Note

The states eDIFF_TYPE_LS_4WD, eDIFF_TYPE_LS_FRONTWD require knowledge of the front wheels to allow torque splits between front and rear axles as well as torque splits across the front axle.

frontWheelIds[0] should specify the wheel on the front axle that is negatively placed on the lateral axis.

frontWheelIds[1] should specify the wheel on the front axle that is positively placed on the lateral axis.

If frontNegPosSplit > 0.5, more torque will be delivered to the wheel specified by frontWheelIds[0] than to the wheel specified by frontWheelIds[1]. The converse is true if frontNegPosSplit < 0.5.

rearBias

PxReal physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::rearBias

Maximum allowed ratio of rear-left and rear-right wheel rotation speeds. The differential will divert more torque to the slower wheel when the bias is exceeded.

Note

Only applied to DIFF_TYPE_LS_4WD and DIFF_TYPE_LS_REARWD

Range: [1, inf)

rearNegPosSplit

PxReal physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::rearNegPosSplit

Ratio of torque split between rear-negative wheel and rear-positive wheels (>0.5 means more to rearWheelIds[0], <0.5 means more to rearWheelIds[1]).

Note

Only applied to DIFF_TYPE_LS_4WD and eDIFF_TYPE_LS_REARWD

Range: [0, 1]

rearWheelIds

PxU32 physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::rearWheelIds[2]

The two rear wheels are specified by the array rearWheelIds.

Note

The states eDIFF_TYPE_LS_4WD, eDIFF_TYPE_LS_REARWD require knowledge of the rear wheels to allow torque splits between front and rear axles as well as torque splits across the rear axle.

rearWheelIds[0] should specify the wheel on the rear axle that is negatively placed on the lateral axis.

rearWheelIds[1] should specify the wheel on the rear axle that is positively placed on the lateral axis.

If rearNegPosSplit > 0.5, more torque will be delivered to the wheel specified by rearWheelIds[0] than to the wheel specified by rearWheelIds[1]. The converse is true if rearNegPosSplit < 0.5.

type

Enum physx::vehicle2::PxVehicleFourWheelDriveDifferentialLegacyParams::type

Type of differential.

Range: [DIFF_TYPE_LS_4WD, eDIFF_TYPE_LS_REARWD]
