the drivetrain without a gear engaged at 8 hz and before the natural frequency has been reached with second gear engaged at 6 5 hz the second gear is disengaged in the transmission so that as the clutch is further engaged and the slip speed is further reduced curve 4 runs along curve 2 below point 6 and up to point 5 in an example embodiment a shifting of the other transmission stage e g an engaged second gear or no second gear is selected for a driving off process in first gear in order to deliberately select the natural frequency of the drivetrain and in order to avoid the formation of a resonance rise at least insofar as possible fig2 shows in another diagram an example embodiment of a procedure for avoiding or reducing chatter vibrations in the right hand sub diagram the speeds of rotation are plotted as a function of the time t while in the left hand sub diagram the depiction according to fig1 is plotted but is turned on its side at t 0 the engagement process begins the engine speed neng is 1400 revolutions per minute and transmission input shaft speed nips1 of the first transmission input shaft is zero at the same time transmission input shaft speed nips2 of the second transmission input shaft is zero since starting from t 0 the clutch is successively engaged for the first gear both transmission input shaft speed nips1 and transmission.
