发明名称 METHOD FOR OPERATING AN AUTOMATIC TRANSMISSION
摘要 The invention relates to a method for operating an automatic transmission (1), comprising a plurality of frictional switching elements (B, C, D, E) and at least one positively engaged switching element (A, F), wherein for the representation of a transmission gear and thus of a flux of force through the automatic transmission (1) at least three switching elements are closed, wherein during a switching operation between two specific transmission gears ("7" and "3") at least two switching elements (D, E) are opened and at least two more switching elements (B, F), including at least one positively engaged switching element (F) and at least one frictional switching element (B), are closed, in the chronological sequence of the switching operation the closing of the positively engaged switching element (F) takes place only after all frictional switching elements (B) are closed.
