GetOutputDriveshaftTorque()

double chrono::vehicle::ChAutomaticTransmissionShafts::GetOutputDriveshaftTorque ( ) const

overridevirtual

Return the transmission output torque on the driveshaft.

This is the torque that is passed to the driveline subsystem, thus providing the interface between the powertrain and vehicle systems.

Implements chrono::vehicle::ChTransmission.

GetOutputMotorshaftSpeed()

double chrono::vehicle::ChAutomaticTransmissionShafts::GetOutputMotorshaftSpeed ( ) const

overridevirtual

Return the transmission output speed of the motorshaft.

This represents the output from the transmision subsystem that is passed to the engine subsystem.

Implements chrono::vehicle::ChTransmission.

HasTorqueConverter()

virtual bool chrono::vehicle::ChAutomaticTransmissionShafts::HasTorqueConverter ( ) const

inlineoverridevirtual

Return true if a torque converter model is included.

A ChAutomaticTransmissionShafts includes a torque converter model.

SetTorqeConverterTorqueRatioMap()

virtual void chrono::vehicle::ChAutomaticTransmissionShafts::SetTorqeConverterTorqueRatioMap ( std::shared_ptr< ChFunctionInterp > &  map )

protectedpure virtual

Set the torque ratio map.

Specify torque ratio as a function of the speed ratio.

Implemented in chrono::vehicle::jeep::Cherokee_AutomaticTransmissionShafts, chrono::vehicle::duro::Duro_AutomaticTransmissionShafts, chrono::vehicle::generic::Generic_AutomaticTransmissionShafts, chrono::vehicle::hmmwv::HMMWV_AutomaticTransmissionShafts, chrono::vehicle::m113::M113_AutomaticTransmissionShafts, chrono::vehicle::marder::Marder_AutomaticTransmissionShafts, chrono::vehicle::mrole::mrole_AutomaticTransmissionShafts, chrono::vehicle::fmtv::FMTV_AutomaticTransmissionShafts, and chrono::vehicle::AutomaticTransmissionShafts.

SetTorqueConverterCapacityFactorMap()

virtual void chrono::vehicle::ChAutomaticTransmissionShafts::SetTorqueConverterCapacityFactorMap ( std::shared_ptr< ChFunctionInterp > &  map )

protectedpure virtual

Set the capacity factor map.

Specify the capacity factor as a function of the speed ratio.

Implemented in chrono::vehicle::jeep::Cherokee_AutomaticTransmissionShafts, chrono::vehicle::duro::Duro_AutomaticTransmissionShafts, chrono::vehicle::generic::Generic_AutomaticTransmissionShafts, chrono::vehicle::hmmwv::HMMWV_AutomaticTransmissionShafts, chrono::vehicle::m113::M113_AutomaticTransmissionShafts, chrono::vehicle::marder::Marder_AutomaticTransmissionShafts, chrono::vehicle::mrole::mrole_AutomaticTransmissionShafts, chrono::vehicle::fmtv::FMTV_AutomaticTransmissionShafts, and chrono::vehicle::AutomaticTransmissionShafts.
