  • Patent number: 10400890
    Abstract: A method for operating a motor vehicle having a transmission (1), the method including closing a first number of shift elements and opening a second number of shift elements in each selected, force locking gear ratio of the transmission (1); closing one shift element less, and therefore opening one shift element more than in a selected, force locking gear ratio when a transmission (1) is not force locking in the sailing mode; adjusting the respectively closed and opened shift elements as a function of at least one operating condition of the motor vehicle in the sailing mode; and checking, at least on the basis of the rotational speed of the transmission input shaft (2), whether a previously closed, positively locking shift element (A, F) to be opened is actually opened in the sailing mode during adjusting of the respectively closed and opened shift elements.
