    • The invention relates to a method for the emergency control of an automatic transmission, wherein the selection and switching operations can be initiated via an actuating shaft that can be pivoted about the longitudinal axis thereof and is supported in an axially displaceable manner, which can be adjusted by means of a selection drive having a selection actuator configured as a direct current electric motor in a selection movement direction and by means of a switching drive having a switching actuator configured as a direct current electric motor in a switching movement direction, and the current selection and switching positions of which can be determined during normal operation by means of a selection sensor unit operatively connected to the selection drive and by means of a switching sensor unit being in operative connection to the switching drive, wherein, in the case of a failure of one of the sensor units, an adjustment position of the respective actuating drive is determined by means of an analysis of at least one electric variable of one of the electric motors as a replacement. In order to increase the operational security, the method according to the invention proposes that the transmission actuator of the actuating drive affected by the failure of the sensor unit be controlled within a selection or switching operation in an actuating time- and/or actuating travel-dependant manner, wherein the determination of a predefined target actuating time tSoll and the calculation of an actuating travel position s each occurs by the analysis of at least one electric variable of one of the electric motors.

    • Limp-home techniques for situations when an electronic shifter of a vehicle malfunctions include detecting, at a controller of the vehicle, a malfunction of the electronic shifter of the vehicle, the electronic shifter being configured to control shifting of a transmission of the vehicle in response to a gear control input provided by operation of the electronic shifter. The techniques include, in response to detecting the malfunction of the electronic shifter, receiving, at the controller, the gear control input from actuation of the one or more actuators of a steering wheel of the vehicle. The techniques also include controlling, by the controller, shifting of the transmission in response to the gear control input received from the one or more actuators of the steering wheel.
