  • Patent number: 9514642
    Abstract: A method for queue recognition by wireless vehicle to vehicle communication includes: checking a relevance for surrounding vehicles from which an ego vehicle receives messages by a comparison with relevance criteria and establishing a relevance if the relevance criteria are satisfied; selecting the speed and position values that are associated with relevant surrounding vehicles and have the speed values indicating a same direction of travel as the ego vehicle; defining a first virtual vehicle to which mean values of selected speed and position values are allocated as values for the at least one first virtual vehicle; recording a time profile of the speed and position values of the at least one first virtual vehicle; recording, as a change value, the time profile of changes in the speed and position values of the first virtual vehicle; and comparing the change value with a queue criterion.
