Method and device for avoiding or reducing chatter vibrations

摘要

Method for avoiding or reducing chatter vibrations in a drive train of a motor vehicle, which has an automated friction clutch and a controller for regulating the degree of opening of the friction clutch and an automated transmission, the controller being given a slip change rate Δnslip / Δt as a controller setpoint specification, if at the beginning or there is slip in the friction clutch during a creeping process of the vehicle and as long as the slip speed nslip is in a critical resonance range, characterized in that the slip rate of change Δnslip / Δt is a function of the operating conditions
