6.1.1.5.7. define_k_factor_curve

define_k_factor_curve(stand_still_torque_ratio=1.0, lockup_speed_ratio=0.0)[source]

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:
