Method for operating drive chain of motor vehicle, involves operating lock-up clutch with controlled reference slip value between initial speeds of lock-up clutch that is equivalent to speed of drive device

摘要

#CMT# #/CMT# The method involves operating a lock-up clutch with a controlled reference slip value between initial speeds of the lock-up clutch that is equivalent to a speed of a drive device. An ending speed (3a) of the lock-up clutch is equivalent to a turbine of a torque converter. A formed actual slip value of the lock-up clutch varies from the reference slip value of the lock-up clutch around a pre-determined limit value. The initial speed of the lock-up clutch is influenced by the drive unit contact, such that the actual slip value takes the reference slip value. #CMT#USE : #/CMT# Method for operating a drive chain of a motor vehicle. #CMT#ADVANTAGE : #/CMT# The initial speed of the lock-up clutch is influenced by the drive unit contact, such that the actual slip value takes the reference slip value, and thus ensures to reduce the overshooting and undershooting of the initial speed of the lock-up clutch in simple and reliable manner with a load tolerance in the drive chain. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a method for operating a drive chain of a motor vehicle. 1a,1a',2a : Curves crosses 3a : Ending speed 4a : Dotted line.
