Member Function Documentation

◆ SetEngineTorqueMaps()

void chrono::vehicle::man::MAN_7t_SimpleMapPowertrain::SetEngineTorqueMaps ( ChFunction_Recorder map0,
ChFunction_Recorder mapF 
)
overridevirtual

Set the engine speed-torque maps.

A concrete class must add the speed-torque points to the provided maps, using the ChFunction_Recorder::AddPoint() function.

Parameters
[out]map0engine map at zero throttle
[out]mapFengine map at full throttle

Implements chrono::vehicle::ChSimpleMapPowertrain.

◆ SetShiftPoints()

void chrono::vehicle::man::MAN_7t_SimpleMapPowertrain::SetShiftPoints ( std::vector< std::pair< double, double >> &  shift_bands)
overridevirtual

Set the ideal shift points for automatic gear shifting.

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

Parameters
[out]shift_bandsdown-shift/up-shift points

Implements chrono::vehicle::ChSimpleMapPowertrain.
