Bei einem Verfahren zur Reduzierung des Abtriebsmoments bei Durchdrehneigung der angetriebenen Räder in Kraftfahrzeugen mittels eines elektronisch gesteuerten Automatikgetriebes, durch dessen Steuergerät die Gangwechsel bei Durchdrehneigung der angetriebenen Räder entsprechend abtriebsmomentreduzierender Schaltkennlinien gesteuert werden, wird die Gangwechselsteuerung entsprechend der abtriebsmomentreduzierenden Schaltkennlinien beendet, wenn nach Ende der Durchdrehneigung der angetriebenen Räder innerhalb einer vorgegebenen Wegstrecke keine erneute Durchdrehneigung auftritt. In a method for reducing the driving torque when the driven wheels of motor vehicles show a tendency to spin using an electronically controlled automatic transmission, the control unit of which controls the gear changes in accordance with gear change characteristics which reduce the driving torque when the driven wheels show a tendency to spin, gear change control in accordance with the said gear change characteristics is ended if, after the driven wheels cease to exhibit a tendency to spin, they do not show a renewed tendency to spin within a predetermined distance travelled.
