Defines the gear box loss model.

Parameters:
  • gear_box_efficiency_parameters_cold_hot (dict) –

    Parameters of gear box efficiency model for cold/hot phases:

    • ’hot’: gbp00, gbp10, gbp01
    • ’cold’: gbp00, gbp10, gbp01
  • equivalent_gear_box_heat_capacity (float) – Equivalent gear box heat capacity [kg*J/K].
  • gear_box_temperature_references ((float, float)) – Reference temperature [°C].
  • initial_gear_box_temperature (float) – Initial gear box temperature [°C].
  • min_engine_on_speed (float) – Minimum engine speed to consider the engine to be on [RPM].
  • gear_box_ratios (dict[int, float | int], optional) – Gear box ratios [-].
Returns:

Gear box loss model.
Return type:

GearBoxLosses

Note

Torque entering the gearbox can be from engine side (power mode or from wheels in motoring mode).
