发明名称 METHOD FOR CARRYING OUT A GEAR SHIFTING OPERATION IN AUTOMATED TRANSMISSIONS
摘要 A method of performing a shift operation in an automatic transmission with at least one form-locking shifting transmission part of a vehicle, with which, during a shift to a target gear (GZIEL), a rotational speed synchronization, between the transmission input rotational speed and the output side rotational speed, is performed. When a different rotational direction is detected between the transmission input and the transmission output, the rotational speed of the transmission input is reduced to a minimum and the target gear (GZIEL) is only shifted when the remaining rotational speed difference, between the rotational speed of the transmission input and the rotational speed of the transmission output can be at least substantially synchronized by the form-locking shift element.
