Abstract

L'invention concerne un système et un procédé de génération de chemin de navigation de stationnement pouvant sélectionner automatiquement une place de stationnement, le procédé consistant : à identifier le type de véhicule d'un véhicule dans lequel est situé un terminal sans fil (401) et à identifier un type de place de stationnement convenant au type de véhicule (102) ; à rechercher toutes les places vides de stationnement dont la taille correspond au type de véhicule dans une portée d'administration, et à envoyer des identifiants de position de toutes les places vides de stationnement trouvées au terminal sans fil (401), et à faire sélectionner par un conducteur l'une quelconque de toutes les places vides de stationnement trouvées en tant que place cible de stationnement (103) ; à demander des informations météorologiques correspondant à la place cible de stationnement pendant une période prédéfinie de temps et à les transmettre au terminal sans fil (401) (104) ; et lorsque les informations d'indication déclarées par le terminal sans fil (401) indiquent qu'un chemin de navigation de stationnement doit être généré, à générer un chemin de navigation de stationnement entre la place cible de stationnement et la position actuelle de véhicule, et à l'envoyer au terminal sans fil (401) pour la navigation de stationnement (105). Grâce à la présente invention, une place de stationnement convenant à un type de véhicule peut être trouvée rapidement afin de garer le véhicule, et un conducteur peut ainsi obtenir des informations météorologiques correspondant à la place de stationnement durant la période prédéfinie de temps à l'avance afin de procéder à des préparations destinées à la protection du véhicule pendant le stationnement.
