- the second vehicle 12 is determined as not belonging to the set of detected objects.
- neither the first item of information, nor the second item of information correspond respectively to a third item of information and a fourth item of information from the table, then the second vehicle 12 is determined as not belonging to the set of objects detected.
- the object detection system of the first vehicle 11 detects only a single object at the rear of the first vehicle 11 and this detection coincides with the time of reception of the request, the comparison described above between the distance information on the one hand and the azimuth on the other hand is not implemented, the probability that the detected object corresponds to the second vehicle 12 being high.
- the first vehicle 11 automatically deduces that the second vehicle 12 is not part of the set of objects detected upon receipt of the request.
- connection request is validated or rejected by the first vehicle 11, depending on the result of the third operation relating to the determination of the correspondence between the second vehicle 12 and an object from the set of detected objects. .
