Method of adjustment of clutch characteristic curve

A method for adjusting a clutch characteristic curve, comprising:

• obtaining a torque-stroke learning value for adjusting the clutch characteristic curve;
• calculating a convergence value for each control point of the clutch characteristic curve;
• calculating a difference value between the convergence value and a characteristic curve value for each control point;
• and
• determining a new characteristic curve value of each control point according to whether a maximum value of the calculated difference values exceeds a preset reference value,
• wherein the determining the new characteristic curve for each control point comprises calculating the new characteristic curve value for each control point based on a preset step size when the maximum value of the calculated difference values exceeds the preset reference value, and
• wherein the calculating the new characteristic curve value for each control point comprises calculating a new characteristic curve value based on a value obtained by multiplying the step size by a ratio of the change value of the corresponding control point to the change value of the control point at which the difference value is the maximum value, for each control point.
