Abstract

The present invention relates to a method for avoiding or reducing chatter vibrations in a drivetrain of a motor vehicle having an automated transmission with which two transmission stages are engageable simultaneously, wherein in particular when driving in a first transmission stage a different transmission stage is specifically engaged, synchronized and/or disengaged, in order to deliberately select the natural frequency of the drive train as a function of the operating point in order to reduce or avoid chatter vibrations.
