Abstract

L'invention concerne un procédé et un dispositif pour trouver une file d'attente de véhicules. L'invention est utilisée pour résoudre le problème lié, dans l'état de la technique, au manque de solution pour trouver une file d'attente de véhicules dans un scénario d'application eV2X. Dans les modes de réalisation de la présente invention, un premier dispositif de communication placé dans une file d'attente de véhicules détermine que la file d'attente de véhicules doit être trouvée par d'autres véhicules ; le premier dispositif de communication envoie des informations de découverte de la file d'attente de véhicules, et un second dispositif de communication placé sur un véhicule reçoit les informations de découverte de la file d'attente de véhicules, envoyées par le premier dispositif de communication placé dans la file d'attente de véhicules ; et le second dispositif de communication détermine que la file d'attente de véhicules est trouvée, d'après les informations de découverte de la file d'attente de véhicules. Dans la présente invention, comme les informations de découverte de la file d'attente de véhicules sont envoyées par le premier dispositif de communication placé dans la file d'attente de véhicules, tous les seconds dispositifs de communication aptes à recevoir les informations de découverte de la file d'attente de véhicules peuvent trouver la file d'attente de véhicules, ce qui fournit une solution simple et efficace de découverte d'une file d'attente de véhicules.
