SCHALTSTEUERUNG IN EINEM AUTOMATISCHEN GETRIEBE

摘要

A clutch-to-clutch shifting in an automatic transmission is disclosed. According to the present invention, a timing at which an off-going element is to be released after engagement process of an on-coming element has been initiated is determined in response to a derivative, with respect to time, of a revolution speed of a rotary element, i.e., an input shaft.
