Member Function Documentation
◆ SetEngineTorqueMaps()
|
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] map0 engine map at zero throttle [out] mapF engine map at full throttle
Implements chrono::vehicle::ChSimpleMapPowertrain.
◆ SetGearRatios()
|
overridevirtual |
Set the gears, i.e.
the transmission ratios of the various gears. A concrete class must populate the vector of forward gear ratios, ordered as 1st, 2nd, etc. and provide a value for the single reverse gear ratio.
- Parameters
-
[out] fwd_gear_ratios list of forward gear ratios [out] reverse_gear_ratio single reverse gear ratio
Implements chrono::vehicle::ChSimpleMapPowertrain.
◆ SetShiftPoints()
|
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_bands down-shift/up-shift points
Implements chrono::vehicle::ChSimpleMapPowertrain.
