Abstract
(EN)
A vehicle early warning method, which is used for preventing false determinations from occurring due to factors such as map accuracy, vehicles crossing over lane lines, and so on, which thereby improves the accuracy of early warning. The present method comprises: an Internet of Vehicles V2X device receiving a V2X message corresponding to a first vehicle; according to the V2X message, the V2X device determining that the first vehicle is a hazardous vehicle in an early warning region, the early warning region being determined according to vehicle information of a second vehicle, and the vehicle information at least comprising: location information of the second vehicle and vehicle dimensions corresponding to the second vehicle; the V2X device outputting early warning information corresponding to the second vehicle. Further disclosed are a vehicle-mounted device and a server, which are used for improving recognition accuracy.
(FR)
La présente invention concerne un procédé d'alerte précoce de véhicule, qui est utilisé pour empêcher des déterminations erronées de se produire en raison de facteurs tels que la précision de carte, des véhicules se croisant sur des lignes de marquage au sol, etc., ce qui améliore ainsi la précision d'alerte précoce. Le présent procédé comprend les étapes suivantes : un dispositif V2X de véhicules reçoit un message V2X correspondant à un premier véhicule ; selon le message V2X, le dispositif V2X détermine que le premier véhicule est un véhicule dangereux dans une région d'alerte précoce, la région d'alerte précoce étant déterminée en fonction d'informations de véhicule d'un second véhicule, et les informations de véhicule comprenant au moins : des informations d'emplacement du second véhicule et des dimensions de véhicule correspondant au second véhicule ; le dispositif V2X délivre des informations d'alerte précoce correspondant au second véhicule. L'invention concerne en outre un dispositif embarqué et un serveur, qui sont utilisés pour améliorer la précision de reconnaissance.
