摘要： A method for operating a motor vehicle drivetrain comprising at least an automatic transmission and a drive assembly. The automatic transmission includes at least five shifting elements to transmit torque and/or power. In each forward and reverse gear, three shifting elements are engaged and the remaining two shifting elements are disengaged. 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.

摘要： A method for operating a multi-speed automatic transmission of a motor vehicle. The automatic transmission has multiple shift elements for transmitting torque and/or power. When in forward and reverse gears, a first number of shift elements are engaged, and a second number of shift elements are disengaged. To improve the shift speed of successive upshifts and/or successive downshifts which are implemented in an overlapped manner, during a first upshift and/or downshift, at least one shift element, necessary for a successive second upshift and/or downshift, is prepared during the first upshift and/or downshift such that when the first upshift and/or downshift reaches a synchronous point, immediate implementation of the successive second upshift and/or downshift is possible. Depending on a gear change to be implemented, the first upshift and/or downshift from a current gear to a desired gear is preferably implemented as a multiple shift rather than a single shift.

摘要： A method of controlling an upshift in a transmission having a main box and a compounder that has at least one gearset and at least one friction element separate from the main box includes initiating an upshift in the main box including application of at least one friction element (e.g. a clutch) in the main box, and releasing a friction element (e.g. a clutch) in the compounder providing a swap shift.

摘要： A method of controlling a downshift in a transmission having a main box and a compounder that has at least one gearset and at least one friction element separate from the main box includes initiating an upshift in the compounder including application of at least one friction element (e.g. a clutch) in the compounder, and releasing a friction element (e.g. a clutch) in the main box providing a swap shift. The speed phase in the compounder may trigger the speed phase in the main box, and vice versa. Target fluid volumes in one or both of a clutch being released in the main box and a clutch being applied in the compounder may be controlled and adjusted, if necessary, as a function of specific event timing in prior shifts.
