Verfahren zum Betreiben eines Automatgetriebes

摘要

A method of operating an automatic transmission of a motor vehicle having a hydraulic system, an electronic control unit connected with the hydraulic system and at least one engageable shifting element which is controlled according to a predetermined time-pressure profile. The method comprising the steps storing an associated profile representative of the operating point of the shifting element with regard to at least one of a filling ratio and a position of one piston of the shifting element. Thereafter, calculating an actual operating point of the shifting element via an algorithm stored in the electronic control unit. Finally, controlling the shifting element by the electronic control unit, via the hydraulic system, based on the calculated actual operating point of the shifting element.
