Member Function Documentation

◆ 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()

◆ SetTorqueConverterCapacityFactorMap()
