  • Adaptation method for controlling shifting elements
    Patent number: 6856881
    Abstract: A system and method for correcting a control of relevant parameters of operation of an automatic transmission having shift elements of a hydraulically-shifted automotive automatic transmission. The influences of an alteration of the internal adaptation parameters on stored external adaptation parameters are taken into account, thus creating a quick-acting and robust adaptation system. The control algorithm is sensitive to a level of the stored external adaptation parameters, to compensate for internal parameter interactivity without requiring comprehensive evaluation of the interaction under all circumstances.
