#CMT# #/CMT# The method involves five shifting elements, three of which are closed for the moment and power transmission in a forward gear and in a reverse gear and two shifting elements are opened. Two successive upshift and two successive downshifts can be executed by control of the five shifting elements. #CMT# : #/CMT# Two successive upshift and two successive downshifts can be executed by control of the five shifting elements in such a manner that a first upshift and downshift is implemented as multiple shift, whereby during the current first upshift and downshift, a single shift or a multiple shift is prepared as following second upshift and downshift. A first shifting element of the automatic transmission is opened during the execution of first upshift and downshift as multiple shifting and thereby switched off as well as a second shifting element of the automatic transmission is closed and thereby switched off. The execution of first upshift and downshift as multiple shift for following second upshift and downshift a third control element of the automatic transmission is provided for opening and thereby switching off as well as a fourth switching element of the automatic transmission is provided for closing and thus switching on. The execution of first upshift and downshift and during the execution of second upshift and downshift, a fifth switching element is held closed or approximately closed. #CMT#USE : #/CMT# For operation of automatic transmission and power supply unit of drive strand of motor vehicle. #CMT#ADVANTAGE : #/CMT# Enables to provide an automatic transmission with a drive strand in which during execution of a first upshift and downshift and subsequent upshift and downshift a moment of the drive device increases and decreases in comparison to a moment that is deviated from a drive input, in order to support the interconnected execution of subsequent upshifts and downshifts. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows the schematic view of the drive strand of the motor vehicle. 1 : Drive unit 2 : Automatic transmission 3 : Wheel 4,5 : Arrow. |
