Method for calculating the touch point of an automatic clutch

摘要

Method for controlling an automated clutch in the power train of a hybrid vehicle with a combustion engine and an electric drive comprises determining the measuring point of the clutch at which a negligible torque is transferred to the clutch and evaluating a signal reply assigned to a theoretical clutch torque obtained from the electric drive. Preferred Features: A theoretical clutch torque applied to the clutch increases until a signal reply is determined in the electric drive. The theoretical clutch torque is modulated. A change in rotation of the electric drive is evaluated as a signal reply.
