摘要:
A method for operating a motor vehicle drivetrain with at least an automatic transmission and a drive motor. The automatic transmission includes at least five shifting elements to transmit torque and/or power. In each forward and reverse gear a maximum of two shifting elements are disengaged while the remaining shifting elements are engaged. Two consecutive gearshifts are carried out through selection of the five shifting elements. During a first gearshift, implemented as a multiple gearshift, a subsequent second gearshift, implemented as either a single or multiple gearshift, is prepared. During the first gearshift, a first shifting element is disengaged, a second shifting element is engaged, a third shifting element is prepared for disengagement in a subsequent second gearshift and a fourth shifting element is prepared for engagement. Further, during the first gearshift and the subsequent second gearshift, a fifth shifting element is retained in at least a substantially engaged state.
