Member Function Documentation
◆ SetGearRatios()
|
overridevirtual |
Set up the gears, i.e.
the transmission ratios of the various gears. A derived class must populate the vector gear_ratios, using the 0 index for reverse and 1,2,3,etc. for the forward gears.
Implements chrono::vehicle::ChShaftsPowertrain.
◆ SetTorqeConverterTorqueRatioMap()
|
overridevirtual |
Set the torque ratio map.
Specify torque ratio as a function of the speed ratio.
Implements chrono::vehicle::ChShaftsPowertrain.
◆ SetTorqueConverterCapacityFactorMap()
|
overridevirtual |
Set the capacity factor map.
Specify the capacity factor as a function of the speed ratio.
Implements chrono::vehicle::ChShaftsPowertrain.
