Abstract:
In an arrangement for controlling an automatically shifting transmission, as a result of a corresponding programming of an electric control device, when actuating a second selecting device, starting from the automatic mode, first an immediate upshifting or downshifting can be prompted and is permitted unless prevented by a specified condition. In the case of a brief actuation, a first or further immediate upshifting and/or downshifting can be prompted and the current or thereby reached gear will be maintained until, first, the duration of the actuation has reached the specific minimum duration and, second, the actuation of the selecting device was terminated. When the second selecting device has a first operating element for the manual triggering of an upshift command and a second operating element for the manual triggering of a downshift command, the event controlling the return to the automatic mode may be the recognition of the simultaneously present commands downshifting and upshifting. After a first actuation of the second selecting device for the purpose of a manually prompted immediate up- or downshifting, a transition may immediately take place to the automatic gear change control according to the automatic mode, if subsequently thereto, an actuation of the second selecting device for the purpose of a gear change in a direction opposite thereto takes place within a comparatively brief time window.
