摘要： A method of controlling a multiple step downshift is disclosed. Two offgoing shift elements are released and two oncoming shift elements are engaged to complete the downshift. During a first phase of the downshift, one of the offgoing shift elements controls the rate of increase of input shaft speed. During a second phase of the downshift, one of the oncoming shift elements controls the rate of increase of the input shaft speed. The method computes target torque capacities such that output torque and input shaft acceleration are continuous during the transition between phases. Furthermore, the method computes target torque capacities such that both oncoming clutches reach zero relative speed simultaneously as the input shaft reaches the final speed ratio.

摘要： A method for the operation of a drivetrain comprising an automatic transmission, a motor and at least five shift elements in which two shift elements are engaged and three shift elements are disengaged. When carrying out an upshift or downshift, a first shift element is either disengaged or engaged, and a second shift element is engaged or disengaged. While the first upshift or downshift is being carried out, a second shift element is prepared for disengaging or engaging and a third shift element is prepared for engaging or disengaging. Actuation of the second shift element occurs by virtue of a minimum selection of a first alternative or a maximum selection a second alternative. While the first upshift or downshift is being carried out and while the second upshift or downshift is being carried out, at least one fourth shift element is kept engaged or nearly engaged.

摘要： An automatic transmission for a vehicle includes a main box controlled using a series of clutches, and an underdrive assembly controlled using a series of clutches and at least one overrunning clutch. In achieving a double-swap downshift from a first transmission “gear” employing a first main box clutch and a first underdrive assembly clutch, to a second transmission “gear” employing a second main box clutch and a second underdrive assembly clutch, a controller delays release of the first main box clutch until after the second underdrive assembly clutch has been prefilled, and fully applies the second underdrive assembly clutch only after slip has been detected in both the main box and the underdrive assembly. Additionally, the controller fully applies the second main box clutch only after the second underdrive assembly clutch has itself been fully applied.

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.

摘要： An automatic transmission achieves a desired shift through an initial stage shift in which a first engagement element is released and a third engagement element is engaged, and a final stage shift in which a second engagement element is released and a fourth engagement element is engaged. A control apparatus sets an estimated rotation acceleration for a transmission input shaft in accordance with an input torque and an input torque rotation acceleration speed, and controls the release of the second engagement element for moving to the final stage shift according to the estimated rotation acceleration. As a result, it is possible to prevent a shifting delay and/or degradation that occurs between the initial stage and the latter stage by continuous transmission of the input rotation (engine rotation) change when moving from the initial stage to the later stage.
