Title:
METHOD FOR PARAMETERIZING A SOFTWARE-BASED VIBRATION ABSORBER FOR DAMPING VIBRATIONS CAUSED BY A GRABBING CLUTCH
Document Type and Number:
WIPO Patent Application WO/2015/158341
Kind Code:
A3
Abstract:
The invention relates to a method for parameterizing a software-based vibration absorber that is connected to a clutch controller in order to dampen grabbing-induced vibrations in a coupling moment to be transmitted via an automated friction clutch which is arranged between an internal combustion engine and a transmission in a motor vehicle powertrain and which is controlled by the clutch controller using a desired coupling moment. In said method, the desired coupling moment affected by grabbing-induced vibrations in predefined operating states is corrected by the software-based vibration absorber, wherein a transmission behavior of a coupling moment that is transmitted via the friction clutch on the basis of the desired coupling moment is ascertained when the desired coupling moment is modulated, and the software-based vibration absorber is parameterized on the basis of the ascertained transmission behavior. In order to be able to quickly and comprehensively parameterize the software-based vibration absorber, the desired coupling moment is modulated using wide-band excitation in a frequency range of the grabbing-induced vibrations, and the transmission behavior is ascertained in accordance with operating parameters of the powertrain.
