Verfahren zur Verminderung von Rupfschwingungen einer Reibungskupplung in einem Antriebsstrang eines Kraffahrzeugs |
摘要 |
A method for reducing chatter vibrations of a friction clutch controlled automatically by a clutch actuator on the basis of a target clutch torque assigned to a clutch torque which is to be transmitted. The clutch has a present actual clutch torque which is marked by vibrations as a result of chatter vibrations which occur occasionally. In order to achieve a reduction of the chatter vibrations, from an input signal that is representative of the clutch torque that is marked by vibrations, on the basis of a vibration-selective guidance variable derived in a torque pattern between internal combustion engine and friction clutch, an absolute amplitude and a phase of the input signal are ascertained on the basis of a transfer function which maps the guidance variable on a vibration-selective clutch torque; from that a correction clutch torque is determined; and using that the target clutch torque is corrected. |
