Abstract: A method is proposed for blocking inadmissible gearshift processes in a transmission with a plurality of shifting devices which, to carry out a shift process, are moved by actuating devices when a shift command is sent by a control unit (TCU) to the relevant actuating device. The actuating devices are connected for data exchange with one another and with the control unit (TCU) in such manner that the actuating device of the shifting device to be shifted is activated provided that clearance has been given by at least one other actuating device.

Abstract: A device for detecting at least the zero-point position of at least one moving component. The device comprises at least one detection device that is fixedly supported relative to the zero-point position of the component. The component has at least one recess in the area of the zero-point position to be detected. The detection device has at least first and second sensors which form a sensor pair. The sensor pair is associated with the recess, in the area of the zero-point position, in order to detect a change of state so that the zero-point position can be detected without moving the component.
