chrono::vehicle::ChAutomaticTransmissionSimpleMap Class Referenceabstract

Description

Template for an automatic transmission model based on a simple gear-shifting model.

This transmission has no torque converter. It accepts a single reverse gear and any number of forward gears. In automatic mode, gear shifting is done based on specified ideal shift points.

Member Function Documentation

◆ GetOutputDriveshaftTorque()

virtual double chrono::vehicle::ChAutomaticTransmissionSimpleMap::GetOutputDriveshaftTorque ( ) const
inlineoverridevirtual

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()

virtual double chrono::vehicle::ChAutomaticTransmissionSimpleMap::GetOutputMotorshaftSpeed ( ) const
inlineoverridevirtual

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.

◆ GetTorqueConverterInputTorque()

virtual double chrono::vehicle::ChAutomaticTransmissionSimpleMap::GetTorqueConverterInputTorque ( ) const
inlineoverridevirtual

Return the input torque to the torque converter.

This simplified model does not have a torque converter.

◆ GetTorqueConverterOutputSpeed()

virtual double chrono::vehicle::ChAutomaticTransmissionSimpleMap::GetTorqueConverterOutputSpeed ( ) const
inlineoverridevirtual

Return the torque converter output shaft speed.

This simplified model does not have a torque converter.

◆ GetTorqueConverterOutputTorque()

virtual double chrono::vehicle::ChAutomaticTransmissionSimpleMap::GetTorqueConverterOutputTorque ( ) const
inlineoverridevirtual

Return the output torque from the torque converter.

This simplified model does not have a torque converter.

◆ GetTorqueConverterSlippage()

virtual double chrono::vehicle::ChAutomaticTransmissionSimpleMap::GetTorqueConverterSlippage ( ) const
inlineoverridevirtual

Return the value of slippage in the torque converter.

This simplified model does not have a torque converter.

◆ HasTorqueConverter()

virtual bool chrono::vehicle::ChAutomaticTransmissionSimpleMap::HasTorqueConverter ( ) const
inlineoverridevirtual

Return true if a torque converter model is included.

A ChAutomaticTransmissionSimpleMap does not model the torque converter.

◆ SetShiftPoints()

virtual void chrono::vehicle::ChAutomaticTransmissionSimpleMap::SetShiftPoints ( std::vector< std::pair< double, double >> &  shift_bands)
protectedpure virtual

Set the ideal shift points for automatic gear shifting.

For each forward gear, specify the min and max engine speed for shifting (down and up, respectively).
