define_k_factor_curve

define_k_factor_curve(stand_still_torque_ratio=1.0, lockup_speed_ratio=0.0)

Defines k factor curve.

Parameters:

• stand_still_torque_ratio (float) –

  Torque ratio when speed ratio==0.

  Note

  The ratios are defined as follows:

  • Torque ratio = gear box torque / engine torque.
  • Speed ratio = gear box speed / engine speed.
• lockup_speed_ratio (float) –

  Minimum speed ratio where torque ratio==1.

  ..note::

  torque ratio==1 for speed ratio > lockup_speed_ratio.

Returns:

k factor curve.

Return type:
