ABSTRACT:
A device for controlling an automatically shifting transmission of a motor vehicle is provided. A first selection device which sets gear speeds adjustable in an automatic mode, a second selection device which manually sets the gears of the transmission in a manual mode provide inputs to an electronic control device. When the second selection device is actuated, the control device commands a gear change in manual mode directly from the automatic mode. After actuation of the second selection device, a verification process is started to check whether a positive longitudinal acceleration process has begun within a predetermined time window. If no positive acceleration process has occurred within the time window, a switch is made back to automatic mode. If a positive acceleration process has occurred, returning to automatic mode is based on factors such as the end of the acceleration mode and repeated acceleration operations in a short time.
