Abstract

Des modes de réalisation illustratifs de l'invention concernent des dispositifs, des procédés et des programmes d'ordinateur pour fournir des informations d'embouteillage par une interface de véhicule à véhicule. L'invention concerne notamment un dispositif (10) destiné à un véhicule (100), lequel dispositif comprend un système (12) pour obtenir des indicateurs d'embouteillage. Ces indicateurs d'embouteillage comprennent au moins un élément du groupe comprenant la vitesse du véhicule (100) ou de véhicules dans un environnement du véhicule (100) et une signalisation d'embouteillage. Le dispositif (10) comprend en outre un système (14) pour déterminer des informations d'embouteillage d'après les indicateurs d'embouteillage. Les informations d'embouteillage indiquent si le véhicule (100) se trouve dans un embouteillage. Le dispositif (10) comprend par ailleurs une interface de véhicule à véhicule (16) conçue pour fournir des informations d'embouteillage à un ou plusieurs autres véhicules (200) par l'intermédiaire d'une liaison de communication de véhicule à véhicule.
