1. A method for operating an automated vehicle, the method comprising:
detecting surroundings data values that represent surroundings of the automated vehicle;
determining positions and predicted movements of objects in the surroundings of the automated vehicle as a function of the surroundings data values;
carrying out a first comparison of the surroundings data values and of the positions and of the predicted movements using an external server, the external server including comparable surroundings data values and comparable positions and comparable predicted movements of the same objects;
determining a driving strategy for the automated vehicle as a function of the positions and the predicted movements of the objects and as a function of the first comparison;
carrying out a second comparison of the driving strategy using the external server, the external server encompassing a comparable driving strategy; and
operating the automated vehicle as a function of the driving strategy and as a function of the second comparison;
wherein, for carrying out the first and second comparison, the surroundings data values and the positions and the predicted movements and the driving strategy, in each case together with information concerning measuring errors and accuracy values and trust values and probability values, are transmitted to the external server,
wherein determining a driving strategy for the automated vehicle as a function of the positions and/or predicted movements of the objects and as a function of the first comparison provides that the driving strategy is determined as a function of the positions and/or predicted movements of the objects when the first comparison leads to the result that first limiting values are not exceeded, and wherein when the first limiting values are exceeded, the driving strategy is replaced by an emergency driving strategy, the emergency driving strategy, including safely parking the automated vehicle in a roadside or a parking area, and
wherein operating the automated vehicle as a function of the driving strategy and as a function of the second comparison provides that the automated vehicle is operated as a function of the driving strategy when the second comparison leads to the result that second limiting values are not exceeded, and wherein when the second limiting values are exceeded, the automated vehicle is operated as a function of the emergency driving strategy, and wherein the external server transmits the emergency driving strategy to the automated vehicle when the second limiting values are exceeded.
