Abstract

A selecting device facilitates selecting operating positions of an automatic transmission of a motor vehicle by the deflection of a selector lever which moves back automatically from all deflecting directions for selecting the individual operating positions. The automatic transmission can be controlled by this selector lever in a first operating mode--selecting individual driving positions in the automatic operation--or, in a second operating mode--step-by-step shifting of the gears in the manual operation. For each operating mode, one operating position of the automatic transmission respectively is assigned to each deflecting direction of the selector lever. The selector lever is movable, in two shifting channels which are essentially disposed perpendicularly with respect to one another such that maximally four operating positions can be selected in each of the two operating modes. In a third operating mode, cruise control functions can be controlled by means of the selector lever.
