define_tc_speed_model(normalized_VDI253_model, m1000_curve_factor, idle_engine_speed)[source]

Define torque converter speed model.

Parameters:
  • normalized_VDI253_model (scipy.interpolate.LinearNDInterpolator) – Normalized VDI253 model function.
  • m1000_curve_factor (float) – Rescaling factor of m1000 curve [N*m/1e6].
  • idle_engine_speed ((float, float)) – Idle engine speed and its standard deviation [RPM].
Returns:

Torque converter speed model.
Return type:
