Abstract

A method and a system for calibrating an estimated clutch characteristic curve of a dual-clutch vehicle transmission are provided. The method includes

mechanically interconnecting a first input shaft with a second input shaft, whereby a transmission output shaft is disengaged;controlling, according to a first alternative, a regulating parameter of a first clutch regulator such that a first friction clutch is engaged with a first torque transmission capability, that a second friction clutch (initially is disengaged, and subsequently engaged; oraccording to a second alternative, that the second friction clutch is initially engaged, a regulating parameter of the first clutch regulator such that the first friction clutch is engaged with a first torque transmission capability, and that the second friction clutch subsequently disengaged; calculating a torque transmission capability of the second friction clutch; and adjusting an estimated clutch characteristic curve of the second friction clutch.
