PxVehicleAutoBoxUpdate

void PxVehicleAutoBoxUpdate(const PxVehicleEngineParams &engineParams, const PxVehicleGearboxParams &gearboxParams, const PxVehicleAutoboxParams &autoboxParams, const PxVehicleEngineState &engineState, const PxVehicleGearboxState &gearboxState, const PxReal dt, PxU32 &targetGearCommand, PxVehicleAutoboxState &autoboxState, PxReal &throttle)

Note

The autobox will not begin a gear change if a gear change is already ongoing.

Note

The autobox will not begin a gear change until a threshold time has lapsed since the last automated gear change.

Note

A gear change is considered as ongoing for as long as PxVehicleGearboxState::currentGear is different from PxVehicleGearboxState::targetGear.

Note

The autobox will not shift down from 1st gear or up from reverse gear.

Note

The autobox shifts in single gear increments or decrements.

Note

The autobox instantiates a gear change by setting PxVehicleCommandState::targetGear to be different from from PxVehicleGearboxState::currentGear

Parameters

engineParams – [in] specifies the engine configuration.
gearboxParams – [in] specifies the gear ratios and the time required to complete a gear change.
autoboxParams – [in] specifies the conditions for switching gear.
engineState – [in] contains the current angular speed of the engine.
gearboxState – [in] describes the current and target gear.
dt – [in] is the time that has lapsed since the last call to PxVehicleAutoBoxUpdate.
targetGearCommand – [inout] specifies the desired target gear for the gearbox. If set to PxVehicleEngineDriveTransmissionCommandState::eAUTOMATIC_GEAR, the value will get overwritten with a target gear chosen by the autobox.
autoboxState – [out] specifies the time that has lapsed since the last automated gear change and contains a record of any ongoing automated gear change.
throttle – [out] A throttle command value in [0, 1] that will be set to 0 if a gear change is initiated or is ongoing.
