A method of operating a drive-train which comprises a drive aggregate, a transmission and a starting clutch connected between the drive aggregate and the transmission such that during rolling and coasting, in a thrust operation, the drive-train is operated in such manner that a target value for the position of the clutch is determined as a function of a transmission input speed. The target value for the position of the clutch is compared with a corresponding actual value and, on the basis of the deviation between the target and actual values, a control parameter is generated for adjusting the clutch. The target value for the position of the clutch, during rolling and coasting, is determined in such manner that for a defined value of the transmission input speed, a target value is determined for the position of the clutch when rolling which is different from that determined when coasting.
