Abstract
A method and device for actuating a shifting arrangement with electric actuators of a transmission control of a motor vehicle. The method includes determining a total current of the shifting arrangement available at a point in time, detecting shift requests of shift elements and compared these with the total available current. Shift requests are then tested according to preset priorities and the sequentially performed according to the priority test. The method avoids exceeding a preset allowed current load, when the requested shifts would exceed the total available current. If the total available current would not be exceeded by the requested shifts, the requests are carried out. A device is also provided in the shifting arrangement which has control and detection mechanisms that monitor current and control the current flow.
