A gearshift device comprises an input unit for receiving input data which is connected via at least one data line to a first controller via which an actuator unit can be controlled for setting a gearbox, especially an automatic gearbox of a motor vehicle, and comprising at least one second controller which is independent of the first controller. The second controller is separate from the first controller and is connected to the input unit via at least one data line. In the case of a fault in the first controller, the actuator unit can be controlled by the second controller at least partially correspondingly to the first controller.

The invention relates to an actuating device for an automatic transmission of a motor vehicle. To allow the motor vehicle to be operated safely and managed conveniently, the invention makes provision for the actuating device to have not only a first device, by which a parking interlock can be engaged and released in normal operation of the actuating device, but also a second device, by which the parking interlock can be engaged in the event of a malfunction.
