Method for adaptation of torque transferred by separation clutch of motor car during operating motor car in e.g. engine starting situations, involves carrying out adaptation of torque according to torque or angular momentum balance

摘要

The method involves adjusting a rotational speed of an electric motor (3), and a preset transferrable torque of a separation clutch (7). The rotational speed of the electric motor is determined. A clutch characteristic curve is corrected based on a difference between expected and actual rotation speeds of the electric motor. The clutch characteristic curve is adapted to an actual transferrable torque by additive and/or multiplicative contributions. Adaptation of the torque transferred by the separation clutch is carried out according to torque or angular momentum balance.
