Calculates gear box efficiency [-].

Parameters:
  • gear_box_powers_out (numpy.array) – Power at wheels vector [kW].
  • gear_box_speeds_in (numpy.array) – Engine speed vector [RPM].
  • gear_box_torques (numpy.array) – Torque gear_box vector [N*m].
  • gear_box_torques_in (numpy.array) – Torque required vector [N*m].
  • min_engine_on_speed (float) – Minimum engine speed to consider the engine to be on [RPM].
Returns:

Gear box efficiency vector [-].
Return type:

numpy.array
