Method for operating a drive train

摘要

#CMT# #/CMT# The method involves implementing shifting up and/or shifting-in as multi-switching, where a switching unit of an automatic transmission (2) is opened and is switched and another switching unit is closed and is switched-on during the execution of the shifting-up and/or shifting-in. Third switching unit is opened and is switched-off and the fourth switching unit is closed and is switched-on during the execution of shifting up and/or shifting-in for another shifting up and/or shifting-in. The fifth switching unit is closed during the execution of two shifting up and/or shifting-in. #CMT#USE : #/CMT# Used for operating a drive-train of a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The method can be applied to the automatic transmission having five switching units in an improved manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a drive train of a motor vehicle. 1 : Drive unit 2 : Automatic transmission 3 : Wheel.
