The invention relates to a transmission system with a shift mechanism for controlling the transmission system, a control device for controlling a transmission system with a shift mechanism, a method for controlling such a transmission system or shift mechanism, as well as an application for the transmission system. In order to shift various gears in a transmission system, particularly an automated shift transmission, shift mechanisms are used. The shift mechanisms include a shift motor and a selection motor, wherein the motors control a selector finger, which is moved in an arrangement including a selection passageway and various shift passageways. The shift passageways are thereby assigned to predetermined gears, so that within the shift passageway there exists one position in which a predetermined gear of the transmission is fully engaged. Through an appropriate mechanism with shift forks, the movement of the selector finger is transmitted to gearshift rings. A selector shaft that is coupled with the selector finger is controlled by the motors in such a way that it can execute swiveling movements around its axis as well as axial movements. The swiveling or linear movements are changed into shift movements or movements of the gearshift rings. Those movements, or especially the movements of the motors, are tracked by passageway and/or angle sensors. They are designed specifically as incremental passageway sensors, hence as sensor devices that detect a position by adding up individual increments along a passageway or an angle. Such shift mechanisms have proven useful, particularly for controlling automated shift transmissions. The use of incremental displacement detection devices has frequently led to cost savings compared with the use of absolute displacement detection devices. Nevertheless, it would be desirable to further improve those known transmission systems with shift mechanisms, particularly with regard to their reliability and shifting accuracy.
