DETAILED DESCRIPTION

[0073] FIG. 1 shows an embodiment of the method for preventing a potential safety-critical traffic situation between a first vehicle and a second vehicle according to the invention in the form of a flow chart. Here, the method steps in accordance with an embodiment of the method for execution by a communication apparatus of a first vehicle according to the invention are depicted on the left side A of FIG. 1, and the method steps in accordance with an embodiment of the method for execution by a processing apparatus according to the invention are depicted on the right side B of FIG. 1. A separate representation of the method steps relative to the method for execution by a communication apparatus of a second vehicle has been dispensed with, since this would correspond to the method for execution by the communication device of the first vehicle relative to the exemplary embodiment shown here.

[0074] In accordance with a step A.1 of the method for execution by a communication apparatus of the first vehicle, a planned trajectory of the first vehicle is output by means of a mobile radio interface of the first vehicle and the planned trajectory is output in parallel by means of a communication interface designed for direct vehicle-to-X communication of the first vehicle.

[0075] In a step B.1 of the method for execution by the processing apparatus, the processing apparatus receives the planned trajectory of the first vehicle. Moreover, according to method steps which are not depicted separately, a planned trajectory of a second vehicle is output by means of a mobile radio interface of the second vehicle and the planned trajectory of the second vehicle is output by means of a communication interface designed for direct vehicle-to-X communication of the second vehicle, and the planned trajectory of the second vehicle is received by the processing apparatus. In a step B.2, the planned trajectory of the first vehicle relative to the planned trajectory of the second vehicle with respect to potential safety-critical situations is evaluated by means of a computing device of the processing apparatus. If, in a step B.3, a potential safety-critical situation is detected, which is depicted by means of Y in FIG. 1, the planned trajectory of the second vehicle is output, to be received by the first vehicle, in a step B.4 by means of an outputting device suitable for communicating via a mobile radio network. If no safety-critical situation is detected in step B.4, the trajectories can be checked or rejected, for example relative to a potential safety-critical situation of possible further received trajectories of further vehicles. Here, a message can also be provided to the first and/or the second vehicle to provide information that no potential safety-critical situation has been detected.

[0076] In a step A.2, the first vehicle receives the planned trajectory of the second vehicle by means of the mobile radio interface and, in a step A.3, the planned trajectory of the second vehicle is transmitted to a maneuver planning device of the first vehicle in order to determine and initiate measures for overcoming the potential safety-critical traffic situation.
